of Tokyo, NTT, the RIKEN Institute, Kyushu University, and the Japan Science and Technology Agency (JST) proposed a new quantum computer architecture that separates memory and processors. This design is highly versatile and portable, and is said to be able to reduce the scale of required hardware by about 40% while limiting the increase in calculation time to about 3% in practical quantum computing. In this study, by proposing a new quantum memory method, it was shown that a memory efficiency of about 90% can be achieved even in practical cases. In addition, the increase in calculation time was suppressed by introducing a cache
