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 ...

Partial quantum information [PDF]
Nature, 2005 Information--be it classical or quantum--is measured by the amount of communication needed to convey it. In the classical case, if the receiver has some prior information about the messages being conveyed, less communication is needed. Here we explore the concept of prior quantum information: given an unknown quantum state distributed over two systems,

Coherent memory for microwave photons based on long-lived mechanical excitations
npj Quantum Information, 2023 Mechanical resonators, due to their capability to host ultralong-lived phonon modes, are particularly attractive for quantum state storage and as memory elements in conjunction with quantum computing and communication networks.

Quantum information leakage [PDF]
Nature Reviews Chemistry, 2020 Decoherence in quantum systems compromises the quantum information processing. However, in molecular systems, coherence is not completely lost and residual coherence can provide important information to guide the design of efficient molecular qubits.

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 ...

Quantum Information Causality [PDF]
Physical Review Letters, 2013 How much information can a transmitted physical system fundamentally communicate? We introduce the principle of quantum information causality, which states the maximum amount of quantum information that a quantum system can communicate as a function of its dimension, independently of any previously shared quantum physical resources.

Concentrating Tripartite Quantum Information [PDF]
Physical Review Letters, 2015 We introduce the concentrated information of tripartite quantum states. For three parties Alice, Bob, and Charlie, it is defined as the maximal mutual information achievable between Alice and Charlie via local operations and classical communication performed by Charlie and Bob.
