High-Efficiency Arbitrary Quantum Operation on a High-Dimensional Quantum System

The ability to manipulate quantum systems lies at the heart of development technology. ultimate goal control is realize arbitrary operations (AQuOs) for all possible open system dynamics. However, demanding extra physical resources impose great obstacles. Here, we experimentally demonstrate a universal approach AQuO on photonic qudit with minimum resource two-level ancilla and $\log_{2}d$-scale circuit depth $d$-dimensional system. then applied in trajectory simulation subspace stabilization Zeno dynamics, as well incoherent manipulation generalized measurements qudit. Therefore, demonstrated complete would play an indispensable role information science.
