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…
Hybrid Quantum Error Correction and Mitigation by Purification
Jonathan Raghoonanan, Tim Byrnes
Quantum error correction physically removes errors from a quantum state, while quantum error mitigation improves observable estimates by processing noisy measurement data. We intro…
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…
Exponential convergence dynamics in Grover's search algorithm
Samuel Cogan, Jonathan Raghoonanan, Tim Byrnes
Grover's search algorithm is the cornerstone of many applications of quantum computing, providing a quadratic speed-up over classical methods. One limitation of the algorithm is th…
