Bosonic quantum codes redundantly encode quantum information in the states of a quantum
harmonic oscillator, making it possible to detect and correct errors. Schrödinger cat codes …

Unidirectional photon emission is crucial for constructing quantum networks and realizing
scalable quantum information processing. In the present work an efficient scheme is …

The interaction strength of an oscillator to a qubit grows with the oscillator's vacuum field
fluctuations. The well-known degenerate parametric oscillator has revived interest in the …

We investigate steady-state thermal transport and photon statistics in a nonequilibrium
hybrid quantum system, in which a qubit shows longitudinal and quadratic coupling with an …

Nonclassical two-photon statistics and photon squeezing are considered as representative
features of the nonclassicality of light. In this work we investigate two-photon correlation …

In this paper, by making use of the nonlinear coherent states approach, the generalized
photon added and subtracted f‐deformed displaced Fock states are introduced. In other …

We propose a scheme to dissipatively stabilize superpositions of squeezed coherent states
for single-and two-resonator modes in superconducting circuits, where a superconducting …

A measurable quadrature of a squeezed quantum state manifests a small uncertainty below
the Heisenberg limit. This phenomenon has the potential to enable several extraordinary …

Coherent long-range interactions between atoms are a prerequisite for numerous
applications in the field of quantum information science. Here we present an appealing …

In this thesis, we study networks of entangled quantum optical systems at different degrees
of complexity, with a special regard to their application to quantum communication …
