Overcoming detection loss and noise in squeezing-based optical sensing
npj Quantum Information, 2021 Among the known resources of quantum metrology, one of the most practical and efficient is squeezing. Squeezed states of atoms and light improve the sensing of the phase, magnetic field, polarization, mechanical displacement. They promise to considerably

Optimal squeezing for quantum target detection
Physical Review Research, 2021 It is not clear if the performance of a quantum lidar or radar, without an idler and only using Gaussian resources, could exceed the performance of a semiclassical setup based on coherent states and homodyne detection.

Measurement of Stokes-operator squeezing for continuous-variable orbital angular momentum
Scientific Reports, 2017 We demonstrate experimentally a measurement scheme for the Stokes operators for the continuous-variable squeezed states of orbital angular momentum (OAM).

de Sitter space as a Glauber-Sudarshan state
Journal of High Energy Physics, 2021 Glauber-Sudarshan states, sometimes simply referred to as Glauber states, or alternatively as coherent and squeezed-coherent states, are interesting states in the configuration spaces of any quantum field theories, that closely resemble classical ...

Low-Noise Amplification of Coherent Single-Mode Squeezed States
PhotonicsQuantum noise fundamentally limits the performance of fiber-optic systems beyond the standard quantum limit (SQL), restricting long-distance quantum key distribution, quantum communication, and precision quantum sensing.

Thermal representations in group field theory: squeezed vacua and quantum gravity condensates
Journal of High Energy Physics, 2020 We apply the formalism of thermofield dynamics to group field theory quantum gravity and construct thermal representations associated with generalised equilibrium Gibbs states using Bogoliubov transformations. The newly constructed class of thermal vacua

Entropy, 2022 The Markovian time evolution of the entropy production rate is studied as a measure of irreversibility generated in a bipartite quantum system consisting of two coupled bosonic modes immersed in a common thermal environment. The dynamics of the system is

Non-Gaussian and Gottesman–Kitaev–Preskill state preparation by photon catalysis
New Journal of Physics, 2019 Continuous-variable quantum-computing is the most scalable implementation of QC to date but requires non-Gaussian resources to allow exponential speedup and quantum correction, using error encoding such as Gottesman–Kitaev–Preskill (GKP) states. However,

Transfer of squeezed coherent state using quantum teleportation of continuous variables
SICE Journal of Control, Measurement, and System IntegrationQuantum entanglement states in continuous-variable quantum teleportation can transfer any quantum state. However, errors occur in the quantum states before and after the transfer in scientific experiments because generating a perfect quantum entanglement
