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

Quantum teleportation constitutes a fundamental tool for various applications in quantum
communication and computation. However, state-of-the-art continuous-variable quantum …

The no-cloning theorem states that an unknown quantum state cannot be cloned exactly and
deterministically due to the linearity of quantum mechanics. Associated with this theorem is …

Gaussian noise induced by loss on Gaussian states may be corrected by distributing
Einstein-Podolsky-Rosen entanglement through the loss channel, purifying the …

A noiseless linear amplifier (NLA) adds no noise to the signals it processes, which works
only in a probabilistic way. It can be realized approximately with either a physical …

Amplification of signals is an elemental function for many information processing systems
and communication networks. However, optical quantum amplification has always been a …

The turbulence channel, as a potential medium for communications, plays a major role in
establishing global quantum networks. However, the weather-tunable channel parameters …

Continuous-variable quantum teleportation enables deterministic teleportation of quantum
states of optical modes. However, the state transfer is imperfect and limited by the amount of …

A partially disembodied quantum state transfer (PDQST) machine is crucial for Gaussian
quantum information processing. It integrates Gaussian quantum teleportation and Gaussian …

Satellite-based quantum key distribution (QKD) has lately received considerable attention
due to its potential to establish a secure global network. Associated with its application is a …
