QuEra’s Libra Fault-Tolerant Quantum System Heading To Amazon Braket Service The rapidly evolving quantum computing industry has quickly spun through two critical stages and now has solidly moved into a third one, according to Yuval Boger, chief commercial officer at QuEra. The first stage was showing that a quantum system – even one with as few as five qubits – could be built. Once that was proven, the next question facing system makers was whether they could correct errors, a crucial test because a quantum system that produces a lot of errors isn’t useful. As we’ve written, there have been significant advances in error correction, such that companies ranging from Microsoft and Google to QuEra and others now say they can. “The third and exciting phase is, 'Can you scale it up? Can you get to a large enough number of qubits that can run useful problems?’” Boger told The Next Platform. “For an end customer, the question has always been, ‘How far is it away from something really useful? What's the gap between where I am and where I need to be?’ That gap has been very, very rapidly narrowed in terms of the time to true use.” Quantum systems continue to evolve with more logical and physical qubits and roadmaps being laid out that stretch into the next decade and preview the coming era of fault-tolerant, scalable commercial computers. QuEra this week is making its next step public, announcing a new quantum system – Libra – that will be hosted on the Braket service at Amazon Web Services, a fully managed cloud service that serves as a unified platform that developers and researchers can use to build and run quantum algorithms across multiple modalities, from superconducting and trapped ions to neutral atoms. Libra, a neutral-atom system, will be
