How Quantum is Quantum Counterfactual Communication? [PDF]
Foundations 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]
Physical 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
2023 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]
Proceedings 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]
Physical 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
IET 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]
Physical 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 ...

Sensors, 2021 In this study, we focus on the 3D surface measurement and reconstruction of translucent objects. The proposed approach of surface-shape determination of translucent objects is based on the combination of the projected laser-beam-based sinusoidal ...
