Quantum Control and Quantum Information Technology [PDF]
The Scientific World Journal, 2013 Quantum information technology has been recognized as one of the most promising future technologies (e.g., see [1]). The development of quantum control theory is a key task for practical quantum information technology (e.g., see [2–4]. Recent advances in quantum information technologies and robust quantum information processing require the dynamics of ...

Information-theoretic interpretation of quantum error-correcting codes [PDF]
, 1997 Quantum error-correcting codes are analyzed from an information-theoretic perspective centered on quantum conditional and mutual entropies. This approach parallels the description of classical error correction in Shannon theory, while clarifying the ...

Quantum Coherence, Coherent Information and Information Gain in Quantum Measurement
, 2019 A measurement is deemed successful, if one can maximize the information gain by the measurement apparatus. Here, we ask if quantum coherence of the system imposes a limitation on the information gain during quantum measurement.

npj Quantum Information, 2023 Entanglement distribution is at the heart of most quantum communication protocols. Inevitable loss of photons along quantum channels is a major obstacle for distributing entangled photons over long distances, as the no-cloning theorem forbids the ...

Quantum information processing with space-division multiplexing optical fibres [PDF]
Communications Physics, 2019 The optical fibre is an essential tool for our communication infrastructure since it is the main transmission channel for optical communications. The latest major advance in optical fibre technology is space-division multiplexing, where new fibre designs

One-way Unlocalizable Information Deficit
, 2013 We introduce one-way unlocalizable information deficit with respect to the one-way information deficit, similar to the definition of one-way unlocalizable quantum discord with respect to one-way quantum discord.

Benchmarking universal quantum gates via channel spectrum
Nature Communications, 2023 Noise remains the major obstacle to scalable quantum computation. Quantum benchmarking provides key information on noise properties and is an important step for developing more advanced quantum processors. However, current benchmarking methods are either

Quantum Information Hidden in Quantum Fields [PDF]
Quantum Reports, 2020 We investigate a possible reduction mechanism from (bosonic) Quantum Field Theory (QFT) to Quantum Mechanics (QM), in a manner that could explain the apparent loss of degrees of freedom of the original theory in terms of quantum information in the reduced one. This reduction mechanism consists mainly of performing an ansatz on the boson field operator,

Negative entropy and information in quantum mechanics [PDF]
, 1997 A framework for a quantum mechanical information theory is introduced that is based entirely on density operators, and gives rise to a unified description of classical correlation and quantum entanglement. Unlike in classical (Shannon) information theory,
