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 …

Major research interests on quantum key distribution (QKD) are primarily focused on
increasing 1. Point-to-point transmission distance (1000 km). 2. Secure key rate (Mbps). 3 …

In quantum cryptography, secret communications are delivered through a quantum channel.
One of the most important breakthroughs in quantum cryptography has been the quantum …

By designing two-step transmissions, this paper presents two quantum dialogue (QD)
protocols that can resist different types of collective noise in the quantum channel. The …

Secret sharing has become a important cryptographic primitive and been widely used. And
quantum secret sharing is a quantum approach to achieve secret sharing. The (t, n) …

We attempt to propose the first orthogonal-state-based protocols of measurement-device-
independent quantum secure direct communication and quantum dialogue employing …

Quantum secure direct communication (QSDC) enables the direct transmission of secret
messages without prior sharing of keys among the communicating parties. However, in …

A quantum switch is a superoperator that, in general, creates a superposition of various
causal orders of two or more quantum dynamics that are all divisible in the complete …

In a controlled quantum secure direct communication (Controlled QSDC) protocol between
three parties, the sender sends the encoded secured message to one of the two receivers …

Quantum networks rely on quantum teleportation, a process where an unknown quantum
state is transmitted between sender and receiver via entangled states and classical …
