Distillation of supersinglet states
Saeed Ahmad, Shuang Li, Jonathan Raghoonanan +3
We introduce an entanglement distillation (purification) protocol for supersinglet states composed of N qubits. The supersinglet state we target is a total spin zero state with zer…

Macroscopic entanglement distribution with atomic ensembles
Shuang Li, Jin Hu, Ilia D. Lazarev +4
The distribution of entanglement is a crucial task for quantum communication towards realizing a globe-spanning quantum internet. Recently a protocol for deterministic long-distanc…

Macroscopic quantum teleportation with ensembles of qubits
Manish Chaudhary, Zhiyuan Lin, Shuang Li +4
We develop methods for performing quantum teleportation of the total spin variables of an unknown state, using quantum nondemolition measurements, spin projection measurements, and…
