Jacob Thomas - your partner Shane Costa and a crew by helicopter to the Monad Facility. They may not be in your cell phone, not in my lifetime, but that at least should be our target,” Sutor concluded."Fire Chief Sturgis answers the call and sends you - Capt. If we do this right, they’re gonna be in cell phone towers that can be all over the place. “We will not just have a few massive quantum computers and data centers. He recommended focusing on creating bigger quantum cores, driving more research and developments on quantum interconnects, distinguishing between intra-system homogeneous and inter-system heterogeneous quantum interconnects, considering the opportunities and threats that inter-system quantum interconnects bring, and aiming for quantum at the edge. “We may hit a point where we’re stuck with small cores for a few years until we get the interconnect problem sorted out.” Sutor expects the progress won’t be steady. We need to build a bigger quantum computer by being able to do quantum operations among smaller quantum cores, and this is how we will grow.” What Should the Industry do Now to Create Bigger Quantum Computers? “We have to entangle across these things. Moreover, those need to be connected using quantum interconnects. Plus, “big enough” quantum systems will need multiple cores, chips, qubit arrays, ion traps, and more, Sutor noted. “But there is a limit, and the limit is relatively small, relative to the hundreds of thousands or millions of qubits we’re going to need, so if I say I can fit 1,000 qubits in this device, but I need 500,000 of them, I got a problem.” “We’re only going to be able to make quantum devices that reach a certain size,” he said. There is a lot of talk about creating more qubits, but Sutor argues the industry should also pay attention to quantum cores. Those qubits must all function with a low error rate, maintain their value sufficiently long, and richly interconnected, while quantum computing providers need to be able to perform 1- and 2- qubit operations fast enough with a low error rate, have techniques to read the computational result accurately, and connect multiple quantum cores. “Moreover, you don’t make big quantum computers just by making more qubits,” Sutor added. “You can’t solve interesting problems with little quantum computers in the same way if your needs are of a modern jet aircraft, and someone’s trying to sell you a bicycle … and it’s even got quantum on the side of the bicycle.” He quoted a 2019 paper from Google indicating that breaking or factoring 2048-bit RSA integers in eight hours needs 20 million noisy qubits. He listed making at least tens of thousands of functional quantum bits (qubits) with low error rates, qubit interconnection, and multiple quantum cores connections as top problems for every provider.īreaking existing encryption systems in a relatively short time requires tens of thousands to millions of qubits, but today’s largest quantum computing systems only have low-hundreds qubits, Sutor pointed out in his talk. Building “big enough” quantum computers is a big engineering challenge with numerous constraints, ColdQuanta VP Bob Sutor noted during this week’s Inside Quantum Technology event.
