Communication security has to evolve to a higher plane in the face of the threat from the
massive computing power of the emerging quantum computers. Quantum secure direct …

Security at the physical layer (PHY) is a salient research topic in wireless systems, and
machine learning (ML) is emerging as a powerful tool for providing new data-driven security …

Quantum secure direct communication (QSDC) is an important branch of quantum
communication that is capable of directly transmitting secret messages over a quantum …

This paper takes advantage of the quantum mechanics to present two efficient circular
controlled quantum communication schemes. The proposed protocols utilize ten qubits for …

Combining with the idea of quantum multi-cast, in this paper, a novel theoretical scheme is
presented to fulfil four-party quantum double-direction cyclic controlled communication by …

The secure multi-party quantum multiplication is one of the primitive operations in quantum
cryptography that plays an important role to design complex quantum protocols like …

In this letter, we systematically analyze the parity properties about Bell states, Pauli
operators and Bell measurements, which are described as four interesting and flexible …

The introduction of quantum walk into quantum teleportation offers a new formation of
entanglement between the position space and the coin space using a conditional shift …

In this paper, a controlled bidirectional quantum secure direct communication (CBQSDC)
protocol is proposed by using six-qubit entangled states. It can successfully avoid the …

Higher channel capacity and noise elimination are the key requirements for the
implementation of long-distance quantum communication. As the additional degrees of …
