Strict Verification of Multiple Indefinite Causal Orders on a Programmable Silicon-Photonic Quantum Chip
Yahohao Deng, Jianwei Wang · 2024
We report strict verification of multiple types of indefinite causal orders and demonstrate distillation of indefinite causal order utilizing a programmable silicon-photonic quantum chip. This experimental implementation contributes to the development of a resource theory for indefinite causal order.
