Quantum computer-aided design of quantum optics hardware

Abstract The parameters of a quantum system grow exponentially with the number involved particles. Hence, associated memory requirement to store or manipulate underlying wavefunction goes well beyond limit best classical computers for systems composed few dozen particles, leading serious challenges in their numerical simulation. This implies that verification and design new devices experiments are fundamentally limited small size. It is not clear how full potential large can be exploited. Here, we present concept computer designed hardware apply it field optics. Specifically, map complex experimental high-dimensional, many-body entangled photons into gate-based circuit. We show explicitly digital simulation Boson sampling realized. then illustrate quantum-optical setups photonic systems, such as high-dimensional Greenberger–Horne–Zeilinger states derivatives. Since already on edge supremacy development rapidly advancing, our approach promises useful tool future device design.
