Exploring experimental limit of deep quantum signal processing using a trapped-ion simulator
J. -T. Bu, Lei Zhang, Zhan Yu +12
Quantum signal processing (QSP), which enables systematic polynomial transformations on quantum data through sequences of qubit rotations, has emerged as a fundamental building blo…
Experimental Verification of Demon-Involved Fluctuation Theorems
L. -L. Yan, J. -T. Bu, Q. Zeng +8
The limit of energy saving in the control of small systems has recently attracted much interest due to the concept refinement of the Maxwell demon. Inspired by a newly proposed set…
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…
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…
