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…

Scalable, high-fidelity all-electronic control of trapped-ion qubits
C. M. Löschnauer, J. Mosca Toba, A. C. Hughes +10
The central challenge of quantum computing is implementing high-fidelity quantum gates at scale. However, many existing approaches to qubit control suffer from a scale-performance…
