Multiphoton quantum metrology without pre- And post-selected measurements
We demonstrate the first protocol for quantum-enhanced phase estimation without pre- and post-selected measurements. Our experiment, with an overall efficiency of 82%, utilizes two-mode squeezed vacuum states and photon-number-resolving detection to surpass the standard quantum limit.
