NetSquid, a NETwork Simulator for QUantum Information using Discrete events [PDF]
Communications Physics, 2020 In order to bring quantum networks into the real world, we would like to determine the requirements of quantum network protocols including the underlying quantum hardware. Because detailed architecture proposals are generally too complex for mathematical

Experimental demonstration of coherence flow in PT- and anti-PT-symmetric systems
Communications Physics, 2021 The gain and loss inherent in non-Hermitian quantum systems can modify the flow of coherence between subsystems, which may be lost or recovered from the environment.

Practical distributed quantum information processing with LOCCNet [PDF]
npj Quantum Information, 2021 Distributed quantum information processing is essential for building quantum networks and enabling more extensive quantum computations. In this regime, several spatially separated parties share a multipartite quantum system, and the most natural set of ...

Optically addressable molecular spins for quantum information processing [PDF]
Science, 2020 Molecular qubits that respond to light Spins in solid-state systems such as quantum dots and defect centers in diamond can easily be controlled by light for use in quantum information processing.

What is quantum information? [PDF]
Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics, 2016 Abstract In the present article we address the question 'What is quantum information?' from a conceptual viewpoint. In particular, we argue that there seems to be no sufficiently good reasons to accept that quantum information is qualitatively different from classical information.

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.

Superconducting nanowire single-photon detectors for quantum information [PDF]
Nanophotonics, 2020 The superconducting nanowire single-photon detector (SNSPD) is a quantum-limit superconducting optical detector based on the Cooper-pair breaking effect by a single photon, which exhibits a higher detection efficiency, lower dark count rate, higher ...

Poisson Quantum Information [PDF]
Quantum, 2021 By taking a Poisson limit for a sequence of rare quantum objects, I derive simple formulas for the Uhlmann fidelity, the quantum Chernoff quantity, the relative entropy, and the Helstrom information. I also present analogous formulas in classical information theory for a Poisson model.

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 ...
