Strong broadband intensity noise squeezing from infrared to terahertz frequencies in lasers with nonlinear dissipation [PDF]

Nanophotonics
The generation and application of squeezed light have long been central goals of quantum optics. Intensity noise squeezing of bright (coherent) states (“bright squeezing”), in contrast to squeezed vacuum, is relatively underdeveloped.

Quadrature squeezing in a nanophotonic microresonator [PDF]

Nature Communications
Squeezed states of light are essential for emerging quantum technology in metrology and information processing. Chip-integrated photonics offers a route to scalable and efficient squeezed light generation, however, parasitic nonlinear processes and ...

Squeezing-enhanced communication without a phase reference [PDF]

Quantum, 2021
We study the problem of transmitting classical information using quantum Gaussian states on a family of phase-noise channels with a finite decoherence time, such that the phase-reference is lost after $m$ consecutive uses of the transmission line.

Scattering-lens based quantum imaging beyond shot noise

Scientific Reports, 2021
The scheme of optical imaging using scattering lens can provide a resolution beyond the classical optical diffraction limit with a coherent-state input.

On the Isomorphism between Dissipative Systems, Fractal Self-Similarity and Electrodynamics. Toward an Integrated Vision of Nature

Systems, 2014
In electrodynamics there is a mutual exchange of energy and momentum between the matter field and the electromagnetic field and the total energy and momentum are conserved.

Transcoherent States: Optical States for Maximal Generation of Atomic Coherence

PRX Quantum, 2020
Quantum technologies are built on the power of coherent superposition. Atomic coherence is typically generated from optical coherence, most often via Rabi oscillations.

Distillation of maximally correlated bosonic matter from many-body quantum coherence [PDF]

Quantum, 2020
We construct quantum coherence resource theories in symmetrized Fock space (QCRTF), thereby providing an information-theoretic framework that connects analyses of quantum coherence in discrete-variable (DV) and continuous variable (CV) bosonic systems ...

Generation and Measurement of Squeezed Vacuum States at Audio-Band Frequencies

Applied Sciences, 2019
Squeezed vacuum states at audio-band frequencies are important quantum resources for practical applications. We demonstrated the generation of squeezed vacuum states at the audio-band frequencies from a subthreshold optical parametric oscillator with a ...

Optimized Squeezing Operation for Phase-Shift Keying Quantum State Discrimination

IEEE Access, 2022
Many receiver designs have been studied in the past to discriminate Phase-Shift Keying (PSK) quantum states that are used to encode information before transmitting over the communication channel.
