Quantum Communications Based on Quantum Hashing [PDF]

open access: yes, 2015
In this paper we consider an application of the recently proposed quantum hashing technique for computing Boolean functions in the quantum communication model. The combination of binary functions on non-binary quantum hash function is done via polynomial

Experimental Satellite Quantum Communications [PDF]

open access: yesPhysical Review Letters, 2014
Quantum Communications on planetary scale require complementary channels including ground and satellite links. The former have progressed up to commercial stage using fiber-cables, while for satellite links, the absence of terminals in orbit has impaired

How Quantum is Quantum Counterfactual Communication? [PDF]

open access: yesFoundations of Physics, 2021
AbstractQuantum Counterfactual Communication is the recently-proposed idea of using quantum physics to send messages between two parties, without any matter/energy transfer associated with the bits sent. While this has excited massive interest, both for potential ‘unhackable’ communication, and insight into the foundations of quantum mechanics, it has ...

Supersonic Quantum Communication [PDF]

open access: yesPhysical Review Letters, 2009
When locally exciting a quantum lattice model, the excitation will propagate through the lattice. The effect is responsible for a wealth of non-equilibrium phenomena, and has been exploited to transmit quantum information through spin chains. It is a commonly expressed belief that for local Hamiltonians, any such propagation happens at a finite "speed ...

Reliable Quantum Communication

open access: yes2023 23rd International Conference on Transparent Optical Networks (ICTON), 2023
The quantum internet, which will be a hybrid of quantum and classical networks, is expected to provide information-theoretic security for data transmission. Classical networks have well-established protocols for reliable end-to-end transmission that use duplicating the classical bits implicitly.

Communicating quantum processes [PDF]

open access: yesProceedings of the 32nd ACM SIGPLAN-SIGACT symposium on Principles of programming languages, 2005
We define a language CQP (Communicating Quantum Processes) for modelling systems which combine quantum and classical communication and computation. CQP combines the communication primitives of the pi-calculus with primitives for measurement and transformation of quantum state; in particular, quantum bits (qubits) can be transmitted from process to ...

Covert Quantum Communication [PDF]

open access: yesPhysical Review Letters, 2016
We extend covert communication to the quantum regime by showing that covert quantum communication is possible over optical channels with noise arising either from the environment or from the sender's lab. In particular, we show that sequences of qubits can be transmitted covertly by using both a single photon and a coherent state encoding. We study the

Reversible quantum communication & systems

open access: yesIET Quantum Communication, 2022
Abstract Quantum Computing has emerged as one of the important dimensions of global research lately, on both the prospects, hardware as well as algorithms. With enhanced processing powers, several architectures based on adiabatic concepts resulting in reversibility have been proposed to date.

Surface Code Quantum Communication [PDF]

open access: yesPhysical Review Letters, 2010
4 pages, 7 figures, 35% loss and 5% error sufficiently low to permit quantum data to be efficiently transmitted arbitrarily far and reliably at a rate limited only by the local gate ...
