Heisenberg-Limited Qubit Read-Out with Two-Mode Squeezed Light

Heisenberg-Limited Qubit Read-Out with Two-Mode Squeezed Light

We show how to use two-mode squeezed light to exponentially enhance cavity-based dispersive qubit measurement. Our scheme enables true Heisenberg-limited scaling of the measurement, and crucially, it is not restricted to small dispersive couplings or unrealistically long measurement times. It involv...
