Sensitivity of quantum gate fidelity to laser phase and intensity noise
X. Jiang, J. Scott, Mark Friesen, M. Saffman
Abstract
The authors analyze gate errors for neutral-atom qubits, quantifying how sensitive gate fidelities are to laser noise for both single- and two-photon gate operation. They consider relevant experimental issues like the noise induced by the finite bandwidth of feedback circuits.
