In a recent remarkable experiment [Sci. Adv. 2, e1501531 (2016)], a 3-qubit quantum
Fredkin (ie, controlled-SWAP) gate was demonstrated by using linear optics. Here we …

Para-particles are fascinating because they are neither bosons nor fermions. While unlikely
to be found in nature, they might represent accurate descriptions of physical phenomena like …

We propose an efficient method for generating two-mode squeezed states of the collective
excitation of two nitrogen-vacancy-center ensembles (NVEs), which are magnetically …

Optimal generation of entangled states is of critical significance for robust quantum
information processing. An effective scheme is presented for speeding up the generation of …

We analyze the stabilizability of entangled two-mode Gaussian states in three benchmark
dissipative models: local damping, dissipators engineered to preserve two-mode squeezed …

Quantum mechanics allows for a consistent formulation of particles that are neither bosons
nor fermions. These para-particles are rather indiscernible in nature. Recently, we showed …

We present an efficient approach for dissipative generation of quantum superposition states
in the microwave resonator, which is coupled to a superconducting qubit. We investigate the …

The generation of two-mode broadband squeezed light is investigated in cascading double-
cavity optomechanical systems. The cavities are driven by amplitude-modulated lasers with …

We propose a dissipative scheme to prepare maximally entangled steady states in cavity
QED setup, consisting of two two-level atoms interacting with the two counter-propagating …

It remains a great challenge to realize direct manipulation of a nitrogen-vacancy (NV) spin at
the single-quantum level with a microwave (MW) cavity. As an alternative, a hybrid system …
