Experimental Implementation of Universal Holonomic Quantum Computation on Solid-State Spins with Optimal Control

Experimental realization of a universal set quantum logic gates with high-fidelity is critical to information processing, which always challenging by inevitable interaction between the system and environment. Geometric computation noise immune, thus offers robust way enhance control fidelity. Here, we experimentally implement recently proposed extensible nonadiabatic holonomic solid spins in diamond at room-temperature, maintains both flexibility resilience against decoherence errors. Compared previous geometric method, fidelities single-qubit two-qubit are improved experiment. Therefore, this work makes an important step towards fault-tolerant scalable realistic systems.
