We revisit the problem of quantum state reconstruction of light beams from the photocurrent quantum noise. As is well-known, but often overlooked, two longitudinal field modes contribute to each spectral component of the photocurrent (sideband modes). We show that spectral homodyne detection is intrinsically incapable of providing all the information needed for the full reconstruction of the two-mode spectral quantum state. Such a limitation is overcome by the technique of resonator detection… 

Phase coherent resonator detection as a complete quantum measurement of the two-mode spectral quantum state of light

The introduction of phase coherence in the detection of quantum noise of light yields a pure quantum measurement of spectral modes. We theoretically show that such coherent quantum measurement

Exploring six modes of an optical parametric oscillator

We measure the complete quantum state for six modes of the electromagnetic field produced by an optical parametric oscillator. The modes we observe in the experiment regard the sideband modes of the

Hexapartite Entanglement in an above-Threshold Optical Parametric Oscillator.

It is shown that the OPO generates a rich structure of entanglement among sets of six optical sideband modes interacting through the nonlinear crystal, potentially bridging nodes of a multicolor quantum network.

Entanglement and squeezing of continuous-wave stationary light

Spectral components of continuous squeezed fields are entangled. In this article we review and clarify this phenomenon by analyzing systematically the relations between the correlations of modes

Spectral homodyne detection, resonator detection, and entanglement in the above-threshold OPO

In the spectral domain, the quantum state of the three beams emitted by an above-threshold optical parametric oscillator encompasses six modes. We use resonator detection to characterize hexapartite

Exploring entanglement in open cavity parametric oscillators: From triply to doubly resonant cavities

We use a versatile model to evaluate the multipartite entanglement and the nonclassical light generation in optical parametric oscillators, exploring the differences between doubly and triply

Entanglement of propagating optical modes via a mechanical interface

Continuous variable entanglement is described between two optical modes mediated by a mechanical oscillator, which paves the way for mechanical systems enabling long-distance quantum information networking over optical fiber networks.

Quantum noise revisited: complete measurement of spectral field modes

We show that quantum noise in the spectral domain usually corresponds to a mixed quantum measurement, and cannot attain complete information about the quantum state of spectral modes [PRL 111, 200402

The question is discussed whether the momentum of a photon has a quantum uncertainty or whether it is a classical quantity. The latter assumption is the main characteristic of reducible Quantum
