该银行表示，它正在使用受“量子启发”的计算能力，以传统计算机速度的300倍执行任务 - 这意味着该机构使用的时量子算法，但不使用量子比特。
去年，澳大利亚联邦银行（Commonwealth Bank of Australia）、联邦政府、新南威尔士州政府和新南威尔士大学（UNSW）共同参与了澳大利亚第一家量子计算公司Telstra总额8300万美元的风险投资。
NatWest has begun testing with quantum computing power to solve the efficiency demand of some of the issues the bank faces.
The bank says it is using “quantum-inspired” computing power, to execute tasks at 300 times the speed of a traditional computer – this meaning that quantum algorithms are used, but not qubits.
The quantum-inspired computing power can be used to help portfolio managers decide on the right composition for the bank’s ￡120 billion “high quality” liquid assets (HQLAs) portfolio.
HQLAs are assets such as cash and bonds that every UK bank must hold as a buffer in case it runs into financial trouble.
The hardware used in testing has been Fujitsu’s quantum-inspired Digital Annealer, whilst the quantum software is provided by 1QBit – of which NatWest is an investor and board observer.
“For the first time, we have the hardware and software necessary to apply our work to industry scale problems, and we look forward to seeing the far-reaching implications of the advancements enabled by these early collaborations,” says Andrew Fursman, CEO of 1Qbit.
The bank hopes to make some processes more efficient, like allowing portfolio managers to adjust the allocation of assets following a surprise movement in the market in a much shorter space of time than normal.
Quantum technology could also be applied to optimise the bank’s other portfolios and areas, like anomaly detection, AI, and software verification.
There are other quantum leaps.
Last year, Commonwealth Bank of Australia joined telco Telstra, the Federal Government, the New South Wales Government and the University of New South Wales (UNSW) in an $83 million venture to found Australia’s first quantum computing company.
