We investigate a new approach for achieving hyperdistillation and hyperentanglement
purification operations simultaneously on two-photon systems, whose state is described by …

Photon loss is one of the main obstacles in long-distance quantum communication. In this
letter, we put forward a highly efficient recyclable amplification protocol for protecting the …

Hybrid quantum gates hold great promise for quantum information processing since they
preserve the advantages of different quantum systems. Here we present compact quantum …

Avian magnetoreception is the capacity for avians to sense the direction of the Earth's
magnetic field. Discovered more than forty years ago, it has attracted intensive studies over …

In this paper, we study an optomechanical device consisting of a Fabry-Pérot cavity with two
dielectric nanospheres trapped near the cavity mirrors by an external driving laser. In the …

In this paper, we propose a scheme to generate an entangled state between two spatially
separated movable mirrors by injecting the two-mode squeezed optical reservoir to the …

Waveguide-coupled optical resonators have played an important role in a wide range of
applications including optical communication, sensing, nonlinear optics, slow/fast light, and …

Entanglement concentration serves as an essential tool to obtain the maximally entangled
states from the less‐entangled states in quantum information processing tasks. An efficient …

In the regime of weak nonlinearity we present two general, feasible schemes for
manipulating photon states. One is an entangler for generating any one of the n-photon …

Both photons and semiconductor quantum-dot (QD) spins are promising candidates for
quantum information science and technology. It is of critical significance to realize high …
