At high temperature, thermal decoherence dominates so that the entanglement of quantum
states is difficult to preserve. Realizing high-temperature entanglement is, therefore, a …

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 present an optical scheme for a SWAP test (controlled swap operation) that can
determine whether the difference between two unknown states (photons) using cross-Kerr …

We represent an optical scheme using cross-Kerr nonlinearities (XKNLs) and quantum dot

A Toffoli gate plays a critical role in many quantum algorithms due to its function as a
building block, which is a fundamental element for feasible large-scale quantum …

With the assistance of weak cross-Kerr nonlinearities, we present a preparation scheme of
four-photon polarization-entangled decoherence-free states, which can be used to construct …

Abstract Concatenated Greenberger–Horne–Zeilinger (C-GHZ) state, which encodes
physical qubits in a logic qubit, has great application in the future quantum communication …

Herein, we present a scheme to prepare a hybrid-entangled W state that possesses the
polarization states of two photons and the time-bin using cross-Kerr nonlinearities (XKNLs) …

We demonstrate the advantages of an optical parity gate using weak cross-Kerr
nonlinearities (XKNLs), quantum bus (qubus) beams, and photon number resolving (PNR) …

Quantum phase estimation (QPE) is the key procedure in various quantum algorithms. The
main aim of the QPE scheme is to estimate the phase of an unknown eigenvalue …
