A non-classical light source is essential for implementing a wide range of quantum
information processing protocols, including quantum computing, networking, communication …

Transfer of quantum states between distant nodes is one of the most important preconditions
for realizing large-scale quantum information processing. We here propose two ways to …

Non-Gaussian quantum states are crucial to fault-tolerant quantum computation with
continuous-variable systems. Usually, generation of such states involves trade-offs between …

We propose an efficient yet simple protocol to generate arbitrary symmetric entangled states
with only global single-qubit rotations in a torn Hilbert space. The system is based on spin …

Cat states, as an important resource in the study of macroscopic quantum superposition and
quantum information applications, have garnered widespread attention. To date, preparing …

A deterministic preparation method for large-amplitude optical Schr\" odinger-cat state is
proposed. The key ingredient is to entangle an atom buried in a single-side cavity with a …

A theoretical scheme to enhance the sensitivity of a quantum fiber‐optical gyroscope
(QFOG) via a non‐Gaussian‐state probe based on quadrature measurements of the optical …

A cascade of two-level superconducting artificial atoms--a source and a probe--strongly
coupled to a semi-infinite waveguide is a promising tool for observing nontrivial phenomena …

We here study a hybrid quantum system of one solid-state electronic spin coupled to a
mechanical resonator (MR) using the crystal strain, with the purpose of engineering the …
