Programmable Two-Particle Bosonic-Fermionic Quantum Simulation System

Quantum computing promises to outperform its classical counterpart substantially. In the past decades, there has been tremendous progress. However, few previous researches have involved programmable systems. Quantum computing is mainly implemented in physics laboratories. This paper proposes a programmable structure. Using the entangled states of photon pairs, we have constructed the whole programmable system including a classical host, constructed with computer and circuits, and a quantum "coprocessor", used for two-particle quantum simulations. A quantum "program" with both classical statements and quantum statements is executed for a certain computation task. The experiment shows high similarity of 95.2% to theoretical result in boson simulation and 97.1% in fermion simulation, which demonstrates the feasibility of our programmable system.
