Nonadiabatic Geometric Quantum Computation with Parametrically Tunable Coupling
Tao Chen, Zheng-Yuan Xue · Physical Review Applied · 2018
Nonadiabatic geometric phases have important applications in quantum computation, as they depend only on the global properties of the evolution paths, and thus are robust against certain types of local noise. Experimental implementation is challenging, though, due to the need for complex control of multilevel or multiple quantum systems. This study proposes a delicate gate implementation to solve the problem, based on parametrically tunable resonant coupling between two superconducting transmon qubits, without introducing any auxiliary state. This approach is promising for high-fidelity geometric manipulation and robust solid-state quantum computing.
