Simple determination of dark states in a general multi-level system
Kaixuan Zhou, June Wu, Junheng Shi +1
In a multi-level energy system with energy transitions, dark states are eigenstates of a Hamiltonian that consist entirely of ground states, with zero amplitude in the excited stat…

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…
