CODES FOR KEY GENERATION IN QUANTUM CRYPTOGRAPHY [PDF]
International Journal of Quantum Information, 2005 As an alternative to the usual key generation by two-way communication in schemes for quantum cryptography, we consider codes for key generation by one-way communication. We study codes that could be applied to the raw key sequences that are ideally obtained in recently proposed scenarios for quantum key distribution, which can be regarded as ...

Simulation of Closed Timelike Curves in a Darwinian Approach to Quantum Mechanics
Universe, 2023 Closed timelike curves (CTCs) are non-intuitive theoretical solutions of general relativity field equations. The main paradox associated with the physical existence of CTCs, the so-called grandfather paradox, can be satisfactorily solved by a quantum ...

Advantage of the Key Relay Protocol Over Secure Network Coding
IEEE Transactions on Quantum Engineering, 2023 The key relay protocol (KRP) plays an important role in improving the performance and the security of quantum key distribution networks. On the other hand, there is also an existing research field called secure network coding (SNC), which has similar ...

Auditing the ‘Social’ of Quantum Technologies: A Scoping Review
Societies, 2022 Various phrases such as “social implications”, social impact” and “ethical, legal and social implications” are used to indicate the impact of a given scientific or technological advancements on the ‘social’.

Quantum Coding Theorem for Mixed States [PDF]
, 1995 We prove a theorem for coding mixed-state quantum signals. For a class of coding schemes, the von Neumann entropy $S$ of the density operator describing an ensemble of mixed quantum signal states is shown to be equal to the number of spin-$1/2$ systems ...

General formulas for capacity of classical-quantum channels [PDF]
, 2002 The capacity of a classical-quantum channel (or in other words the classical capacity of a quantum channel) is considered in the most general setting, where no structural assumptions such as the stationary memoryless property are made on a channel.

Generalized Perfect Codes for Symmetric Classical-Quantum Channels
IEEE Transactions on Information Theory, 2022 We define a new family of codes for symmetric classical-quantum channels and establish their optimality. To this end, we extend the classical notion of generalized perfect and quasi-perfect codes to channels defined over some finite dimensional complex Hilbert output space.
