PsiQuantum, a start-up based in Palo Alto, California, has developed a technique it claims to be 50X more efficient in the run-time efficiency of compiled applications in fault-tolerant quantum computers.
Pete Shadbolt, Chief Scientific Officer and Co-Founder of PsiQuantum, said: “This is a very significant achievement by our fault-tolerance team. A 50X improvement means that a quantum application which would have previously taken a month to execute on a future photonic quantum computer, would now run in less than a day.”
Naomi Nickerson, VP Quantum Architecture of PsiQuantum: “This development also has implications given the ability of photonic quantum computers to exploit trade-offs between computing resources and computing runtime. The active volume technique reduces the computational time required and this can be translated into reduced hardware resources using techniques like photonic interleaving. This is also likely to be of practical importance in allowing programs to run in the same time using less hardware. Though the advantages of this approach can be realized with any technology able to connect distant qubits, this is challenging for many of the current approaches, and active volume architectures are particularly suited to photonic qubits connected using optical fiber.”
