**UK cyber spy chief says: quantum computing is closer but beware the risk**

That means we need to get ahead of the curve – we need to be designing quantum-resistant algorithms, we need to be designing quantum-proof cyber security approaches Quantum computing is coming closer – its still some way off…

**“This risks creating an arms race”: inside Europe’s battle over the future of quantum computing**

It is, after all, fiendishly difficult, and immensely expensive, to build a transistor that is smaller than an atom. John Morton, a nanoelectronics professor at UCL and a co-founder of Quantum Motion, compares the current race…

**Adding or subtracting single quanta of sound**

Indeed, quite counterintuitively, when you subtract a single phonon, the average number of phonons actually goes up to 2n. At first thought, you may expect this would simply change the average to n + 1 or n – 1, respectively, however the actual outcome…

**Quantum Computer Completed A 2.5-Billion-Year Task In 200 Seconds –**

The goal is to achieve quantum supremacy (aka quantum advantage) – when a quantum computer vastly outperforms a conventional machine on a given task. This year, a China team developed a photon-based quantum computer that demonstrated quantum supremacy – the second…

**$715,000,000 Bitcoin (BTC) Wallet Up For Grabs Among Crypto Sleuths**

Quantum volume measures a variety of different metrics, including the number quantum physics computing bits (qubits), efficiency, and the strength of the interconnection between the system’s qubits. Present-day quantum computers are not nearly powerful enough to actually crack cryptographic systems, though…

**Why coronavirus hit people from BAME communities so hard**

“There’s so many different elements to this, systemic, you know, structural racism,” says Abi. 🔊 Listen to The WIRED Podcast, the week in science, technology and culture, delivered every Friday 👉 Follow WIRED on Twitter, Instagram, Facebook and LinkedIn “It’s a very…

**Dublin researchers develop single photon emitter from quantum dots**

They say this approach could be key to practical quantum computers, quantum communications, and other quantum devices. For applications such as quantum computing, it is necessary to control emissions from these dots and to produce quantum entanglement of emission from pairs of…

**Trinity scientists create new device to light up the way for quantum technologies**

For applications such as quantum computing, it is necessary to control emissions from these dots and to produce quantum entanglement of emission from pairs of these dots. This strong field can also couple emission from pairs of quantum…
