Quantum sensors that compute: quantum computational magnetic-field sensing using a superconducting qubit
Purnendu Sen, Mathieu Ouellet, Saeed A. Khan +6
A measurement of a single-qubit quantum sensor reveals at most 1 bit of information about the signal that was sensed. To perform a classification task on the signal, the convention…

Single-gate, multipartite entanglement on a room-temperature quantum register
Joseph D. Minnella, Mathieu Ouellet, Amelia R. Klein +1
Multipartite entanglement is an essential aspect of quantum systems, needed to execute quantum algorithms, implement error correction, and achieve quantum-enhanced sensing. In soli…
