The leading turkey quantum computing companies and institutions in 2026 form a state-led ecosystem, organised around government research, defence-industry partners, universities, and a small but real commercial layer. Turkey is unusual among emerging quantum nations because it has already built a domestic quantum computer, the QuanT processor, through a partnership between a university and a defence company. Ten organisations define the turkey quantum computing companies landscape in this guide: Qubitrium, TOBB ETU, ASELSAN, TUBITAK BILGEM, TUBITAK, Bilkent University, Koc University, Turkcell, TRUBA, and QTurkey.
Why Turkey’s quantum ecosystem is state-led
Turkey’s quantum landscape is state-led, and it is important to be clear about that. The country does not have a deep field of venture-funded quantum startups. The turkey quantum computing companies landscape is built mostly from government research units, the defence industry, universities, and the national research agency, with a small commercial layer led by Qubitrium.
What makes Turkey distinctive is what this state-led model has already produced. Through a partnership between TOBB ETU and the defence-electronics company ASELSAN, Turkey has built QuanT, a domestically developed quantum computer, and the government has set up a dedicated quantum-research division inside TUBITAK BILGEM. The turkey quantum computing companies landscape is therefore an emerging ecosystem driven from the top, by the state and the defence industry, and it has reached real milestones that many larger commercial ecosystems have not.
QuanT and Turkey’s quantum computer
The headline achievement of the turkey quantum computing companies ecosystem is QuanT, described as the first domestically developed Turkish quantum computer. QuanT is a five-qubit superconducting processor, built through a partnership between TOBB University of Economics and Technology and the defence-electronics company ASELSAN, and unveiled in November 2024. The two partners set up a joint quantum-technologies laboratory in 2022 with support from Turkey’s Secretariat of Defence Industries, and TOBB ETU brought years of work on superconducting electronics to the effort.
A small quantum computer like QuanT is not going to outperform the large machines built by the major international companies, and it is best understood as a national capability rather than a commercial product. What it gives Turkey is the engineering experience of designing, fabricating, and operating a real quantum processor, which is exactly the experience a country needs if it wants to build quantum hardware. QuanT puts Turkey in a small group of countries that have built a quantum computer of their own, and it is the centrepiece of the turkey quantum computing companies landscape.
The top turkey quantum computing organisations
Ten organisations define the turkey quantum computing companies landscape covered in this guide. Because the ecosystem is state-led, most are government bodies, defence-industry partners, and universities. TOBB ETU and ASELSAN built the QuanT quantum computer, TUBITAK BILGEM runs the government quantum-research division, and TUBITAK is the national research funder. Bilkent University and Koc University are the main academic research centres, Qubitrium is the leading commercial quantum company, Turkcell is the telecom operator testing quantum communication, TRUBA is the national supercomputer, and QTurkey is the education network. The Qubitrium quantum-technology company anchors the commercial layer of the turkey quantum computing companies.
The profiles below cover the leading organisations in depth. Each entry sets out what the organisation does and why it matters to Turkey’s wider quantum effort.
What the landscape reveals
The first pattern is that Turkey’s quantum effort is driven by the state and the defence industry. QuanT was built by a university and a defence company, the dedicated quantum-research division sits inside a government centre, and the national funder shapes the field. The Turkey quantum companies landscape reflects a top-down model in which national capability, rather than commercial return, is the main goal.
Turkey has reached real milestones
The second pattern is that this model has delivered concrete results. Turkey has a domestically built quantum computer in QuanT, a government quantum-research division, and demonstrated quantum-secure communication links. The Turkey quantum companies landscape has produced more visible milestones than many ecosystems with larger commercial sectors, which is a genuine strength.
The commercial layer is small but real
The third pattern is that the commercial layer, though small, exists and is serious. Qubitrium is a real quantum company with hardware in space, and Turkcell is testing quantum communication on its own network. The Turkey quantum companies landscape is not purely academic, and the commercial side has room to grow as the state-built foundation matures.
The research base behind Turkish quantum
Turkey’s quantum research rests on a mix of universities and government research bodies. TOBB ETU in Ankara is the centre of quantum-hardware work, with its superconducting-electronics expertise and its role in building QuanT. Bilkent University, also in Ankara, carries real strength in quantum devices, nanophotonics, and quantum sensing, an area of quantum technology that is closer to practical use than quantum computing.
Koc University in Istanbul brings strong microphotonics research, working on the optical components that quantum communication depends on. The Quantum Technologies Division of TUBITAK BILGEM, near Istanbul, carries out government research into quantum cryptography, random number generation, and sensing. Together these institutions give the Turkey quantum companies a research base that spans quantum hardware, quantum sensing, photonics, and quantum security, supported by the TRUBA national supercomputer for classical and hybrid computing.
The Ankara and Istanbul map
The Turkey quantum companies landscape is concentrated in two cities. Ankara, the capital, is the centre of quantum hardware and government-linked research. It hosts TOBB ETU and ASELSAN, the partners behind the QuanT quantum computer, Bilkent University with its quantum-devices research, the national research agency TUBITAK, and the TRUBA national supercomputer. Ankara is where Turkey’s quantum-hardware and state-research activity is based.
Istanbul, the largest city, is the centre of the commercial and communication side. It hosts Qubitrium, the country’s leading quantum company, Koc University with its microphotonics research, and Turkcell, the telecom operator testing quantum communication. The Quantum Technologies Division of TUBITAK BILGEM is in Gebze, in Kocaeli province near Istanbul. Between Ankara’s hardware and research strength and Istanbul’s commercial and communication activity, Turkey has a compact two-city quantum landscape.
When Turkey matters for your quantum strategy
Quantum-secure communication
If your priority is quantum-secure communication, Turkey is genuinely relevant. Qubitrium develops quantum cryptography and has flown quantum-communication hardware to space, Turkcell has demonstrated quantum key distribution on its fibre network, and TUBITAK BILGEM works on quantum security for civil and defence use. Organisations interested in quantum-secure communication, particularly across the region where Europe and Asia meet, should account for the Turkey quantum companies.
Quantum sensing and devices
For quantum sensing and quantum devices, Turkey offers real research capability. Bilkent University works on quantum devices, nanophotonics, and quantum sensing, and TUBITAK BILGEM works on quantum imaging and sensing. Quantum sensing is one of the most mature branches of quantum technology, and organisations seeking research partners in precision quantum measurement should consider the Turkey quantum companies.
Quantum hardware collaboration
For quantum-hardware collaboration, Turkey has something few emerging quantum nations can offer, which is real experience of building a quantum computer. The QuanT effort, led by TOBB ETU and ASELSAN, has given Turkey hands-on experience with superconducting quantum hardware. Organisations interested in the engineering of quantum processors, or in working with a country building its own quantum-hardware capability, should consider the Turkey quantum companies.
Frequently asked questions
Who are the leading Turkey quantum companies in 2026?
Turkey’s quantum landscape is state-led rather than company-led. The central organisations are TOBB ETU and the defence-electronics company ASELSAN, which together built QuanT, Turkey’s first domestically developed quantum computer, and TUBITAK BILGEM, which runs the government quantum-research division. TUBITAK is the national research funder, Bilkent University and Koc University are the main academic research centres, and TRUBA is the national supercomputer. Qubitrium is the leading commercial quantum company, working on quantum cryptography and communication, and Turkcell is the telecom operator testing quantum key distribution. QTurkey is the education and community network. Together these ten organisations define the Turkey quantum companies landscape, a state-led ecosystem with a small but real commercial layer.
Does Turkey have a quantum computer?
Yes. Turkey has built QuanT, described as its first domestically developed quantum computer, through a partnership between TOBB University of Economics and Technology and the defence-electronics company ASELSAN.
QuanT is a five-qubit superconducting processor, unveiled in November 2024, and the two partners have run a joint quantum laboratory to develop it. A small machine like QuanT is best understood as a national capability rather than a commercial product, because it is not designed to compete with the large machines built by major international companies. What QuanT gives Turkey is real engineering experience in designing, fabricating, and operating a quantum processor, which puts the Turkey quantum companies in a small group of ecosystems that have built a quantum computer of their own.
What is Qubitrium?
Qubitrium is an Istanbul-based quantum-technology company, founded in 2020, and it is the clearest commercial quantum company in the Turkey quantum companies ecosystem. Qubitrium develops quantum cryptography, quantum communication, and quantum sensing, and its work includes quantum-key-distribution payloads designed for small satellites, one of which has flown to low Earth orbit. Quantum key distribution protects communications against the future threat that a powerful quantum computer could break today’s encryption, and carrying out quantum communication from space extends the reach of quantum-secure links beyond what ground fibre can cover. Qubitrium shows that the Turkey quantum companies are not purely academic, and it gives Turkey a genuine commercial presence in space-based quantum communication.
What is TUBITAK BILGEM’s role in Turkish quantum?
TUBITAK BILGEM is Turkey’s national informatics and information-security research centre, and in 2023 it established a dedicated Quantum Technologies Division. The division carries out government research into quantum cryptography, quantum random number generation, quantum key distribution, and quantum imaging and sensing, for both civil and defence applications. A dedicated government quantum-research unit gives a country a stable, well-resourced base for quantum technology that does not depend on the success of individual startups, and it lets the state build quantum capability directly. TUBITAK BILGEM gives the Turkey quantum companies a government research division focused on the security and sensing side of quantum technology, and it is one of the main reasons the Turkish ecosystem is described as state-led.
Where is quantum technology developed in Turkey?
The Turkey quantum companies landscape is concentrated in two cities. Ankara, the capital, is the centre of quantum hardware and government-linked research, hosting TOBB ETU and ASELSAN, the partners behind the QuanT quantum computer, Bilkent University with its quantum-devices research, the national research agency TUBITAK, and the TRUBA national supercomputer. Istanbul, the largest city, is the centre of the commercial and communication side, hosting Qubitrium, the leading quantum company, Koc University with its microphotonics research, and Turkcell, the telecom operator testing quantum communication. The Quantum Technologies Division of TUBITAK BILGEM is in Gebze, in Kocaeli province near Istanbul. Between Ankara and Istanbul, Turkey has a compact two-city quantum landscape.
Why is Turkey’s quantum sector described as state-led?
Turkey’s quantum sector is described as state-led because its main achievements have come from the government, the defence industry, and universities rather than from venture-funded startups. The QuanT quantum computer was built by a university, TOBB ETU, together with the defence-electronics company ASELSAN. The dedicated quantum-research division sits inside the government centre TUBITAK BILGEM, and the national research agency TUBITAK directs funding and policy across the field. This top-down model aims at building national capability rather than commercial return, and it has delivered concrete milestones. The commercial layer of the Turkey quantum companies does exist, led by Qubitrium, but it is small, which is why the ecosystem as a whole is best understood as state-led.
Does Turkey have commercial quantum companies?
Turkey has a small commercial quantum layer rather than a deep one. The clearest pure-play quantum company is Qubitrium, an Istanbul firm founded in 2020 that works on quantum cryptography, communication, and sensing, and has flown quantum-communication hardware to space. Beyond Qubitrium, large incumbents engage with quantum technology as an adjacent line: the defence-electronics company ASELSAN co-built the QuanT quantum computer, and the telecom operator Turkcell has tested quantum key distribution on its fibre network. Turkey does not yet have a wide field of venture-funded quantum startups, so the commercial side of the Turkey quantum companies is concentrated in one specialist company and a few large firms exploring quantum technology.
How does Turkey compare with other quantum nations?
Turkey is an emerging, state-led quantum nation with an unusual profile. It does not have the venture-funded company ecosystems of countries such as the Netherlands, Finland, or Germany, and its commercial quantum layer is small. But Turkey has done something many larger ecosystems have not, building a domestic quantum computer, QuanT, through a university and defence-industry partnership, and setting up a dedicated government quantum-research division. The Turkey quantum companies landscape competes through state capability, defence-industry scale, and real milestones in quantum hardware and quantum communication. As the state-built foundation matures and the commercial layer grows, Turkey’s position among quantum nations should strengthen.
