Chiral switching of many-body steady states in a dissipative Rydberg gas
Chongwu Xie, Konghao Sun, Kang-Da Wu +4
Dissipative Rydberg gases are an outstanding platform for the investigation of many-body quantum open systems. Despite the wealth of existing studies, the non-equilibrium dynamics…
Nonlinearity-Enhanced Continuous Microwave Detection Based on Stochastic Resonance
Kang-Da Wu, Chongwu Xie, Chuan-Feng Li +3
In practical sensing tasks, noise is usually regarded as an obstruction to better performance and will degrade the sensitivity. Fortunately, \textit{stochastic resonance} (SR), a c…
Resource Theory of Imaginarity: New Distributed Scenarios
Kang-Da Wu, Tulja Varun Kondra, Carlo Maria Scandolo +5
The resource theory of imaginarity studies the operational value of imaginary parts in quantum states, operations, and measurements. Here we introduce and study the distillation an…
Implementing quantum dimensionality reduction for non-Markovian stochastic simulation
Kang-Da Wu, Chengran Yang, Ren-Dong He +5
Complex systems are embedded in our everyday experience. Stochastic modelling enables us to understand and predict the behaviour of such systems, cementing its utility across the q…
Preserving quantum correlations and coherence with non-Markovianity
Marek Miller, Kang-Da Wu, Manfredi Scalici +5
Open quantum systems exhibit a rich phenomenology, in comparison to closed quantum systems that evolve unitarily according to the Schrödinger equation. The dynamics of an open quan…
Experimental study of quantum uncertainty from lack of information
Yuan-Yuan Zhao, Filip Rozpędek, Zhibo Hou +4
Quantum uncertainty is a well-known property of quantum mechanics that states the impossibility of predicting measurement outcomes of multiple incompatible observables simultaneous…
Experimental progress on quantum coherence: detection, quantification, and manipulation
Kang-Da Wu, Alexander Streltsov, Bartosz Regula +3
Quantum coherence is a fundamental property of quantum systems, separating quantum from classical physics. Recently, there has been significant interest in the characterization of…
Resource theory of imaginarity: Quantification and state conversion
Kang-Da Wu, Tulja Varun Kondra, Swapan Rana +5
Complex numbers are widely used in both classical and quantum physics, and are indispensable components for describing quantum systems and their dynamical behavior. Recently, the r…
Minimizing back-action through entangled measurements
Kang-Da Wu, Elisa Bäumer, Jun-Feng Tang +5
When an observable is measured on an evolving coherent quantum system twice, the first measurement generally alters the statistics of the second one, which is known as measurement…
Nonlocality, steering and quantum state tomography in a single experiment
Chang-Jiang Huang, Guo-Yong Xiang, Yu Guo +5
We investigate whether paradigmatic measurements for quantum state tomography, namely mutually unbiased bases and symmetric informationally complete measurements, can be employed t…
Operational Resource Theory of Imaginarity
Kang-Da Wu, Tulja Varun Kondra, Swapan Rana +5
Wave-particle duality is one of the basic features of quantum mechanics, giving rise to the use of complex numbers in describing states of quantum systems, their dynamics, and inte…
Detecting Non-Markovianity via Quantified Coherence: Theory and Experiments
Kang-Da Wu, Zhibo Hou, Guo-Yong Xiang +4
The dynamics of open quantum systems and manipulation of quantum resources are both of fundamental interest in quantum physics. Here, we investigate the relation between quantum Ma…
Experimentally reducing the quantum measurement back-action in work distributions by a collective measurement
