Photons have been a flagship system for studying quantum mechanics, advancing quantum
information science, and develo** quantum technologies. Quantum entanglement …

Research in quantum information processing has followed two different directions: the use of
discrete variables (qubits) and that of high-dimensional, continuous-variable Gaussian …

In principle, optical phase-sensitive amplifiers are known to be capable of realizing
noiseless amplification, as well as improving the signal-to-noise-ratio of optical links by 3 dB …

We investigate the resources needed for secure teleportation of coherent states. We extend
continuous variable teleportation to include quantum teleamplification protocols that allow …

Genuinely quantum states of a harmonic oscillator may be distinguished from their classical
counterparts by the Glauber-Sudarshan P representation—a state lacking a positive P …

This review covers recent theoretical and experimental efforts to extend the application of
the continuous-variable quantum technology of light beyond" Gaussian" quantum states …

Quantum amplification enables the enhancement of weak signals and is of great importance
for precision measurements, such as biomedical science and tests of fundamental …

Real photonic devices are subject to photon losses that can decohere quantum information
encoded in the system. In the absence of full fault tolerance, quantum error mitigation …

Photons are the best long-range carriers of quantum information, but the unavoidable
absorption and scattering in a transmission channel places a serious limitation on viable …

Detection of weak electromagnetic waves and hypothetical particles aided by quantum
amplification is important for fundamental physics and applications. However …
