Gaussian Quantum Information [PDF]
Reviews of Modern Physics, 2011 The science of quantum information has arisen over the last two decades centered on the manipulation of individual quanta of information, known as quantum bits or qubits.

Quantum Coherence, Coherent Information and Information Gain in Quantum Measurement [PDF]
EPL (Europhysics Letters), 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.

Quantum information effects [PDF]
Proceedings of the ACM on Programming Languages, 2022 We study the two dual quantum information effects to manipulate the amount of information in quantum computation: hiding and allocation. The resulting type-and-effect system is fully expressive for irreversible quantum computing, including measurement.

Infrared Quantum Information [PDF]
Physical Review Letters, 2017 We discuss information-theoretic properties of low-energy photons and gravitons in the S-matrix. Given an incoming n-particle momentum eigenstate, we demonstrate that unobserved soft photons decohere nearly all outgoing momentum superpositions of charged particles, while the universality of gravity implies that soft gravitons decohere nearly all ...

Quantum information transmission [PDF]
Quantum Information Processing, 2012 We present a scheme of quantum information transmission, which transmits the quantum information contained in a single qubit via the quantum correlation shared by two parties (a two-qubit channel), whose quantum discord is non-zero. We demonstrate that the quantum correlation, which may have no entanglement, is sufficient to transmit the information of

An ultra-high gain single-photon transistor in the microwave regime
Nature Communications, 2022 Successfully controlling an optical signal by a single gate photon would have great applicability for quantum networks and all-optical computing. Here, the authors realise a single-photon transistor in the microwave regime based on superconducting ...
