Probing the Full Distribution of Many-Body Observables by Single-Qubit Interferometry
Zhenyu Xu, Adolfo del Campo
We present an experimental scheme to measure the full distribution of many-body observables in spin systems, both in and out of equilibrium, using an auxiliary qubit as a probe. We…

Experimentally accessible lower bounds for genuine multipartite entanglement and coherence measures
Yue Dai, Yuli Dong, Zhenyu Xu +3
Experimentally quantifying entanglement and coherence are extremely important for quantum resource theory. However, because the quantum state tomography requires exponentially grow…

Extreme Decoherence and Quantum Chaos
Zhenyu Xu, Luis Pedro García-Pintos, Aurélia Chenu +1
We study the ultimate limits to the decoherence rate associated with dephasing processes. Fluctuating chaotic quantum systems are shown to exhibit extreme decoherence, with a rate…
