Observation of hierarchy of Hilbert space ergodicities in the quantum dynamics of a single spin
Wenquan Liu, Zouwei Pan, Yue Fu +4
Ergodicity, the property that all allowed configurations are explored over time, plays a pivotal role in explaining the equilibrium behavior of classical dynamical systems. Yet, su…
Experimental test of the Crooks fluctuation theorem in a single nuclear spin
Wei Cheng, Wenquan Liu, Zhibo Niu +3
We experimentally test the Crooks fluctuation theorem in a quantum spin system. Our results show that the Crooks fluctuation theorem is valid for different speeds of the nonequilib…
Experimental test of the Jarzynski equality in a single spin-1 system using high-fidelity single-shot readouts
Wenquan Liu, Zhibo Niu, Wei Cheng +5
The Jarzynski equality (JE), which connects the equilibrium free energy with non-equilibrium work statistics, plays a crucial role in quantum thermodynamics. Although practical qua…
Experimental study on the principle of minimal work fluctuations
Wei Cheng, Wenquan Liu, Yang Wu +5
The central quantity in the celebrated quantum Jarzynski equality is , where is work and is the inverse temperature. The impact of quantum randomness on the fluctu…
