Quantum computing could be useful faster than anyone expectedPrevious work carried out by Goldman Sachs together with IBM, for instance, estimated that to achieve quantum advantage would require a device supporting 7,500 logical qubits. Goldman Sachs has, for many years, been digging into the potential that quantum technologies have to disrupt the financial sector. Because of the vast spectrum of possibilities, this is one of the most compute-intensive tasks in finance, which requires making large numbers of predictions about different market movements. It’s not only a matter of counting qubits: for quantum computers to resolve calculations reliably, the devices will also have to be optimized to avoid errors. To achieve this objective, the team traded off some calculation speed in return for some hardware gains. To compare, IBM is currently working on releasing a 127-qubit processor this year.
