In this paper, we propose a robust and high-fidelity scheme to construct a nondestructive
Rydberg parity meter by optimized inverse engineering, after which we can know the parity …

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

Parity meter is the core step of many quantum information works. In this paper, a robust and
accurate protocol to construct a parity meter of two artificial atoms coupled to a cavity is …

We present a scheme for teleporting a generic two-photon polarization state by using two
EPR states as quantum channel based on weak cross-Kerr nonlinearities. As the core …

We present a scheme of two-photon quantum Fourier transform at first, where the controlled
π/2 phase gate and the Hadamard gates are applied. The indirect interaction between two …

We present two error-tolerance transmission protocols of a single-photon polarization state
when bit-flip error is taken into account. For achieving the transmission target of the single …

In this paper, a robust and accurate protocol is proposed to realize nondestructive parity
measurement of artificial atoms using a superconducting resonator and homodyne …

We propose an arbitrary controlled-unitary (CU) gate and a bidirectional transfer scheme of
quantum information (BTQI) for unknown photons. The proposed CU gate utilizes quantum …

In this paper, a protocol for nondestructive parity meter (NPM) of two cat‐state qubits is
proposed. The physical model contains two cavities and an auxiliary qubit. For each cavity …

A quantum entanglement distribution protocol of a four-photon χ-type polarization-entangled
state is presented by exploiting spatial degree of freedom, which is immune to an arbitrary …
