An overview of quantum phase transitions (QPTs) in metallic ferromagnets, discussing both
experimental and theoretical aspects, is given. These QPTs can be classified with respect to …

High-dimensional quantum systems expand the Hilbert space, enabling the processing of
more intricate information and the execution of wider quantum operations. The development …

In this paper, with the weak cross-Kerr nonlinearity, we first present a special experimental
scheme called controlled-path gate with which the realization of all possible bipartite …

Concurrence provides us an effective approach to quantify entanglement, which is quite
important in quantum information processing applications. In the paper, we mainly review …

The Gottesman-Kitaev-Preskill (GKP) qubit is a promising ingredient for fault-tolerant
quantum computation (FTQC) in optical continuous variables due to its advantage of noise …

Relying on weak cross-Kerr nonlinearities, we propose a nearly deterministic generation
scheme of the three-photon polarization-entangled perfect W state which can be applied to …

We propose a hybrid quantum computing scheme where qubit degrees of freedom for
computation are combined with quantum continuous variables for communication. In …

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 …

Magnetization, resistivity, and specific heat measurements were performed on solution-
grown single crystals of R Fe 2 Zn 20 and R Co 2 Zn 20 (R= Y, Nd, Sm, Gd-Lu). Whereas …

In this paper, we consider a method for implementing a quantum logic gate with photons
whose wave function propagates in a one-dimensional Kerr-nonlinear photonic crystal. The …
