Pound–Drever–Hall (PDH) laser frequency stabilization is a powerful technique widely used
for building narrow linewidth lasers. This technique is, however, ineffective in suppressing …

Inevitable interactions with the reservoir largely degrade the performance of entangling
gates, which hinders practical quantum computation from coming into existence. Here, we …

The fidelity of gate operations on neutral atom qubits is often limited by fluctuations of the
laser drive. Here, we quantify the sensitivity of quantum gate fidelities to laser phase and …
