Quantum key distribution (QKD) promises information theoretic secure key as long as the
device performs as assumed in the theoretical model. One of the assumptions is an absence …

We present an efficient protocol to securely compute the summation and multiplication of the
multiparty secure numbers via quantum states in MUBs. In our protocols, we assume the …

In this work, we present optical schemes for secure direct quantum communication of digital
and analog signals using continuum coherent states and frequency-dependent phase …

In this paper, a quantum dialogue protocol is proposed based on four-qubit Cluster state,
which constructed a new quantum channel. By using Bell measurements and the …

We present a scheme for joint remote implementation of an arbitrary single-qubit operation
following some ideas in one-way quantum computation. All the senders share the …

We present a scheme for multiparty-controlled joint remote preparation of an arbitrary m-
qudit state by using d-dimensional Greenberger-Horne-Zeilinger (GHZ) states as the …

Quantum key distribution (QKD) is an innovative solution in the cryptography world to
prevent the information leakage that can sometimes be deliberate. Several QKD protocols …

In a recent paper, the quantum-chaotic key distribution (QCKD) in optical networks was
introduced. In the present work, we extend the QCKD theory in two ways: Firstly, we propose …

We propose two novel schemes for multicast-based remote preparation of two kinds of two-
qubit states with the aid of the eight-qubit entangled states as the quantum channels. In our …

We present a self-error-correction spatial-polarization hyperentanglement distribution
scheme for N-photon systems in a hyperentangled Greenberger–Horne–Zeilinger state over …
