Thermooptic reconfigurable Mach Zehnder quantum interference device
Abstract
Integrated Mach-Zehnder (MZ) quantum optic circuit is one of most promising approaches for generation and reconfiguration of complex quantum interference. Here, multi photons quantum entanglement is formulated in terms of thermooptic phase change in MZ interferometer having 3 dB two mode interference couplers (MZ-TMI). The manipulation of quantum entanglement is demonstrated theoretically, opening a way to design silicon based quantum optic technology platform for quantum processing applications. Our results also provide multi-photon quantum interference with high fabrication tolerance and fidelity of 0.98 ± 0.01 within smaller dimension than previous implementation of MZ component.
