ホロノミーへの粒子のペアリング

Holonomies are of great interest to quantum computation and simulation. The geometrical nature of holonomies offers increased stability to quantum gates. Furthermore, symmetries of particle physics are naturally reflected in holonomies, making them ideally suited for quantum simulation of quantum chromodynamics and grand unified theories. Yet, practically designing quantum holonomies with the required properties and scale is challenging. Here, we construct a new class of holonomies by increasing the particle number. We show that multiparticle holonomies can even exist in systems devoid of any single-particle holonomies. We present a comprehensive framework for multiparticle quantum holonomies and experimentally realize various two-particle holonomies in integrated photonics. Our results enable the number of particles to be harnessed as a design parameter, offering increased freedom in constructing holonomic systems.
