Submicrosecond high-fidelity dispersive readout of a spin qubit with squeezed photons

Submicrosecond high-fidelity dispersive readout of a spin qubit with squeezed photons

This work focuses on enhancing the dispersive readout of a single electron spin qubit by utilizing displaced squeezed vacuum states for the probe photons. The built-in quantum correlations of squeezed photons lead to significant improvements in qubit readout fidelity and speed.
