A new quantum network dialogue protocol is designed by using the entanglement property
of the continuous-variable single-mode squeezed states. To verify the security of the …

Quantum properties are the prerequisite for quantum states to be applied in quantum state
engineering. Here, we first propose a theoretical scheme of generating a novel kind of non …

Based on the conditional measurement and beam splitters, multi-photon catalysis is
introduced to each mode of even entangled coherent states (EECSs). The resulted states …

Photon subtraction (PS) is an important operation for optic quantum information processing.
Conventional PS is implemented using a single linear beam splitter (BS) and photon …

The entanglement improvement is theoretically investigated when applying a single-side
quantum scissors (SSQS) with a local squeezing operation and two-asymmetrical beam …

A new kind of non-Gaussian quantum state is introduced by applying nonlocal coherent
superposition (τa+ sb) m of photon subtraction to two single-mode squeezed vacuum states …

In a previous paper Zhan et al.(2022) proposed the coherent state representation for linear
operator, which shows a beautiful theoretical value. Inspired by the work, we further extend it …

We theoretically investigate the nonclassicality and entanglement properties of non-
Gaussian entangled states generated by using a number-conserving generalized …

In this paper, We investigate three-mode photon-added Greenberger-Horne-Zeilinger (GHZ)
entangled coherent states by repeatedly operating the photon-added operator on the GHZ …

The non-Gaussian operation, which can be easily implemented by current techniques, is an
effective way for the improvement of the continuous-variable entanglement. Here, we …
