Rigetti Computing, Inc., a leader in commercial quantum computing systems, has announced the next generation of its cloud-based quantum experience service. The company has upgraded its 40Q and 80Q systems to deliver more qubits and at a higher operating speed than in past generations. By introducing the world’s first commercial multi-chip quantum processor – “Aspen M,” the improvement demonstrates the speed with which Rigetti is advancing its technology, as well as its commitment to providing the public with a transparent view into the progress of quantum computing.
The new systems come just after the launch of Rigetti’s first quantum computer on the cloud and represent another major milestone in the company’s mission to build practical quantum computers for business and science. The new system has twice the number of qubits – the basic processing unit in quantum computers.
In addition to doubling the number of qubits, the new system delivers a 2.5x speedup in quantum processing times and reduces readout errors by up to 50 per cent. This will help to improve the reliability of quantum program results.
Rigetti also announced its partnership with Deloitte and Strangeworks to explore quantum computing applications. The partnership will use Rigetti’s platform and the company’s quantum processor to explore how to solve problems that require the enormous computational power of a quantum computer.
In particular, the collaborators are interested in using the new scalable processor to explore quantum applications in material simulation, optimization, and machine learning. Deloitte’s team will focus on how to identify use cases for which quantum computing holds promise; Strangeworks will provide expertise on operating systems and applications where these devices offer an advantage over conventional computers.
In a test example, The company used the same set of data from the New York Stock Exchange in a task where its algorithms were asked to predict whether a stock would close higher or lower at the end of the day. In this case, however, the system was asked to make a prediction about tomorrow’s closing price. The results on both systems showed Rigetti’s scale advantage, which demonstrates that quantum computers could compete with industry-standard classical computers previously used for these tasks.
An optimization problem with 65 variables was also targeted using the Rigetti “Aspen M” processor. The result showed that the optimization problem which classical computers would ordinarily find difficult to run was able to run in the Aspen M system in under 5 minutes. This application can be used in industries for supply chain, logistics, and network optimization.
Deloitte is a multinational professional services company. It is one of the big four accounting organizations and the largest professional services network in the world by revenue and number of professionals.
Strangeworks is a leading quantum service provider that makes the power of quantum computing accessible to everyone all in one place.
