Energy-conversion device using a quantum engine with the work medium of two-atom entanglement

J. -W. Zhang, B. Wang, W. -F. Yuan +7

Although entanglement is considered as an essential resource for quantum information processing, whether entanglement helps for energy conversion or output in the quantum regime is…

Single-Atom Verification of the Optimal Trade-Off between Speed and Cost in Shortcuts to Adiabaticity

J. -W. Zhang, J. -T. Bu, J. C. Li +11

The approach of shortcuts to adiabaticity enables the effective execution of adiabatic dynamics in quantum information processing with enhanced speed. Owing to the inherent trade-o…

Spin Fluctuations in SrLaRuO

Zheng He, Qisi Wang, Yu Feng +12

We use inelastic neutron scattering to study spin fluctuations in SrLaRuO, where Lanthanum doping triggers a Lifshitz transition by pushing the van Hove singula…

Enhancement of quantum heat engine by encircling a Liouvillian exceptional point

J. -T. Bu, J. -Q. Zhang, G. -Y. Ding +10

Quantum heat engines are expected to outperform the classical counterparts due to quantum coherences involved. Here we experimentally execute a single-ion quantum heat engine and d…

Dynamical Control of Quantum Heat Engines Using Exceptional Points

J. -W. Zhang, J. -Q. Zhang, G. -Y. Ding +11

A quantum thermal machine is an open quantum system coupled to hot and cold thermal baths. Thus, its dynamics can be well understood using the concepts and tools from non-Hermitian…

Single-atom verification of the noise-resilient and fast characteristics of universal nonadiabatic noncyclic geometric quantum gates

J. W. Zhang, L. -L. Yan, J. C. Li +6

Quantum gates induced by geometric phases are intrinsically robust against noise due to their global properties of the evolution paths. Compared to conventional nonadiabatic geomet…
