Quantum cryptography is arguably the fastest growing area in quantum information science.
Novel theoretical protocols are designed on a regular basis, security proofs are constantly …

Quantum-enhanced measurements exploit quantum mechanical effects for increasing the
sensitivity of measurements of certain physical parameters and have great potential for both …

We derive a computable analytical formula for the quantum fidelity between two arbitrary
multimode Gaussian states which is simply expressed in terms of their first-and second …

Quantum optical Gaussian states are a type of important robust quantum states which are
manipulatable by the existing technologies. So far, most of the important quantum …

We derive Markovian master equations for single and interacting harmonic systems in
different scenarios, including strong internal coupling. By comparing the dynamics resulting …

We review the physical phenomena that arise when quantum mechanical energy levels are
modulated in time. The dynamics resulting from changes in the transition frequency is a …

The entanglement properties of non-Gaussian states are investigated, which are obtained
by performing the photon addition, photon subtraction, photon-addition-then-subtraction …

We analyze the Uhlmann fidelity of a pair of n-mode Gaussian states of the quantum
radiation field. This quantity is shown to be the product of an exponential function depending …

We establish several upper bounds on the energy-constrained quantum and private
capacities of all single-mode phase-insensitive bosonic Gaussian channels. The first upper …

We propose a reliable entanglement measure for a two-mode squeezed thermal state of the
quantum electromagnetic field in terms of its Bures distance to the set of all separable states …
