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 ...

Quantum Information Scrambling on a Superconducting Qutrit Processor [PDF]
, 2020 The theory of quantum information provides a common language which links disciplines ranging from cosmology to condensed-matter physics. For example, the delocalization of quantum information in strongly-interacting many-body systems, known as quantum ...

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 ...

Quantum Information Scrambling in a Trapped-Ion Quantum Simulator with Tunable Range Interactions. [PDF]
Physical Review Letters, 2020 In ergodic many-body quantum systems, locally encoded quantum information becomes, in the course of time evolution, inaccessible to local measurements. This concept of "scrambling" is currently of intense research interest, entailing a deep understanding

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 ...

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.

Observation of a quantum phase transition in the quantum Rabi model with a single trapped ion
Nature Communications, 2021 Quantum phase transition occurs in many-body systems with abrupt changes in the ground state around zero temperature. Here the authors report signatures of quantum phase transition in single trapped ion that can be described using quantum Rabi model.
