We review some current ideas of tripartite entanglement. In particular, we consider the case
representing the next level of complexity beyond the simplest (though far from trivial) one …

One of the most fascinating aspects of quantum networks is their capability to distribute
entanglement as a nonlocal communication resource. In a first step, this requires network …

A scheme for distributed quantum measurement that allows nondestructive or indirect Bell
measurement was proposed by Gupta et al [1]. In the present work, Gupta et al.'s scheme is …

Measurement-based quantum computation (MQC) is a leading paradigm for building a
quantum computer. Cluster states being used in this context act as one-way quantum …

We propose a generation scheme of χ-type entangled states based on weak cross-Kerr
nonlinearities. After Homodyne measurement, the individual photons can be entangled …

Employing a polarization-entangled χ χ state, which is a four-photon genuine entangled
state, we propose a protocol teleporting a general two-photon polarization state. Firstly, the …

A Fredkin gate is an indispensable logic gate for the applications of the scalable quantum
network. Weak cross-Kerr nonlinearities serve as the intermediary between photons and …

Based on the circuit including linear optical elements, a fault-tolerant distribution of GHZ
states against collective noise among three parties is proposed. Additionally, two controlled …

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 propose a construction scheme of a two-photon polarization controlled arbitrary phase
gate based on weak cross-phase modulation. Assisted with weak cross-phase modulation …
