Science friction: some tire of waiting for quantum’s leap

Use cases for new tech are piling up – from CVA to VAR. But so are the obstacles

If qubits – the building blocks of a quantum computer – were humans, no-one would employ them. They would be unreliable. They would forget everything they learned. Only trivial jobs could be entrusted to them, and then only after painstakingly marshalling them into teams. On top of all that, they would insist on meticulously prepared and maintained workspaces.
