Two-Particle Bosonic-Fermionic Quantum Walk via Integrated Photonics

摘要: Quantum walk represents one of the most promising resources for simulation physical quantum systems, and has also emerged as an alternative to standard circuit model computing. Here we investigate how particle statistics, either bosonic or fermionic, influences a two-particle discrete walk. Such experiment been realized by exploiting polarization entanglement simulate bunching-antibunching feature noninteracting bosons fermions. To this scope novel three-dimensional geometry waveguide is introduced, which allows accurate independent behavior, maintaining remarkable control on both phase balancement.
