Enhancement of frequency metrology with ultrafast squeezed states of multimode light

Jonathan Roslund, Yin Cai, Claude Fabre +1 more

Multimode squeezed states are used to enhance the measurement of optical frequency fluctuations beyond the standard quantum limit. A multichannel detector is employed, which enables simultaneous extraction of orthogonal parameters characterizing the light field.

Multimode squeezed light generation and characterization

Alexander Chudakov, Vladislav Severin, Anastasia Poshevkina +5 more

Nowadays, the realization of quantum computations and communications based on continuous variables has attracted a significant attention due to a substantial expansion of the system dimensionality. The main progress in this area is attributed to the implementation of multimode systems based on squeezed states of light. One of the simplest ways to generate such states relies upon their producing in a single-pass optical parametric amplifier (OPA) using ultrafast pumping. However, for homodyne detection of such multimode states, the profile of the local oscillator (LO) must perfectly match the profile of the measured mode. Usually, this is not the case; therefore a proper treatment of multimode squeezing is required. In this work, we study both theoretically and experimentally the multimode squeezed light generated in type-0 and type-II OPA. We characterize such sources and investigate the degree of squeezing in dependence on the LO spectral profile, employing a pulse shaping technique. The theoretical analysis is performed using the Schmidt-mode theory. This work might have a significant impact on the realization of multimode quantum protocolsNowadays, the realization of quantum computations and communications based on continuous variables has attracted a significant attention due to a substantial expansion of the system dimensionality.

Photon subtraction from a multimode squeezed vacuum state

Adrien Dufour, Clément Jacquard, Young-Sik Ra +2 more

We present the generation and characterization of a multimode non-gaussian state. We prepare squeezed vacua in multiple time-frequency modes, subtract a single photon, and then characterize the state by using mode-selective homodyne detection.
