Gaussian quantum information [PDF]
Reviews of Modern Physics, 2012 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 computers, quantum cryptography and quantum teleportation are among the most celebrated ideas that have emerged from this new field.

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.

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.

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.

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 ...

Quantum simulation for topological Euler insulators
Communications Physics, 2022 A new class of topological systems has been recently discovered, it has been dubbed the Euler insulator and can manifest in two-dimensional systems. The authors present an experimental implementation for realizing the Euler insulator with 171Yb+ ion ...

Experimental investigation of wave-particle duality relations in asymmetric beam interference
npj Quantum Information, 2022 Wave-particle duality relations are fundamental for quantum physics. Previous experimental studies of duality relations mainly focus on the quadratic relation D 2 + V 2 ≤ 1, based on symmetric beam interference, while a linear form of the duality ...
