Quantum supremacy with spin squeezed atomic ensembles
Yueheng Shi, Junheng Shi, Tim Byrnes
We propose a method to achieve quantum supremacy using ensembles of qubits, using only spin squeezing, basis rotations, and Fock state measurements. Each ensemble is assumed to be…

Fundamental Limits of the Dew-Harvesting Technology
Minghao Dong, Zheng Zhang, Yu Shi +3
Dew-harvesting technology radiatively cools a condenser below the dewpoint to achieve condensation of the water vapor from the atmosphere. Due to its passive nature, this technolog…

Direction-Dependent Parity-Time Phase Transition and Non-Reciprocal Directional Amplification with Dynamic Gain-Loss Modulation
Alex Y. Song, Yu Shi, Qian Lin +1
We show that a dynamic gain-loss modulation in an optical structure can lead to a direction-dependent parity-time (PT) phase transition. The phase transition can be made thresholdl…
