Interlocked Time Crystal in Coupled Spin-1/2 Ensembles under Local Dissipation
Zhen-Huan Yang, Zhen-Tao Liang, Dan-Bo Zhang
The paper shows that coupling two spin‑½ ensembles with opposite pumping and decay can generate a synchronized, non‑equilibrium time‑crystalline phase, even though each ensemble al…
Probing Quantum Information Scrambling via Local Randomized Measurements
Yan-Ming Chen, Dan-Bo Zhang
In quantum many-body dynamics, locally encoded information typically scrambles across the entire system, becoming inaccessible to local probes. The upper bound of accessible inform…
Revealing quantum operator scrambling via measuring Holevo information on digital quantum simulators
Bin Sun, Geng-Bin Cao, Xi-Dan Hu +1
Quantum operator scrambling describes the spreading of local operators into the whole system in the picture of Heisenberg evolution, which is often quantified by the operator size…
Exact Correlation Functions for Dual-Unitary Quantum circuits with exceptional points
Xi-Dan Hu, Dan-Bo Zhang
Dual-unitary quantum circuits can provide analytic spatiotemporal correlation functions of local operators from transfer matrices, enriching our understanding of quantum dynamics w…
