"We’ve demonstrated for the first time that a quantum computer can be used to solve a simplified version of a securities settlement optimisation problem, including modelling credit and collateral pools. If we were to scale up to real-world volumes of tens of thousands of transactions in a batch, we’d need to first wait a few years for quantum hardware to evolve and mature. Every few months, the number of qubits goes up – but to run securities settlement netting, we’d need orders of magnitude more qubits than exist at present.”
