Critical metrology relies on the precise preparation of a system in its ground state near a
quantum phase transition point where quantum correlations get very strong. Typically, this …

Quantum coherence reflects the origin of quantumness and might be capable of extracting
the subtle nature of a system. We investigate the ground-state coherence and steered …

We propose what we believe is a novel proposal for realizing a quantum C-NOT logic gate,
through fabricating an interesting hybrid device with a chiral photon-pulse switch, a single …

Engineering strong single-photon optomechanical couplings is crucial for optomechanical
systems. Here, we propose a hybrid quantum system consisting of a nanobeam (phonons) …

An investigation to significantly enhance coupling to nitrogen− vacancy (NV) centers at a

We investigated the transmission of single and two photons in a one-dimensional
waveguide that is coupled with a Kerr micro-ring resonator and a polarized quantum emitter …
