Trapped-ion two-qubit gates with >99.99% fidelity without ground-state cooling
A. C. Hughes, R. Srinivas, C. M. Löschnauer +6
We introduce the 'smooth gate', an entangling method for trapped-ion qubits where residual spin-motion entanglement errors are adiabatically eliminated by ramping the gate detuning…
Subspace Leakage Error Randomized Benchmarking of Mølmer-Sørensen Gates
R. T. Sutherland, A. C. Hughes, J. P. Marceaux +3
We demonstrate a new technique that adapts single-qubit randomized benchmarking to two-qubit Mølmer-Sørensen gates. We use the controllable gate phase to generate Cliffords that ac…
Comparison of trapped-ion entangling gate mechanisms for mixed species
V. M. Schäfer, A. C. Hughes, O. Bazavan +4
Entangling gates are an essential capability of quantum computers. There are different methods for implementing two-qubit gates, with respective advantages and disadvantages. We in…
