Near-limit quantum control beyond analytic tractability in many-body spin systems
Jixing Zhang, Bo Peng, Yang Wang +11
As quantum control approaches hardware-imposed performance limits, weak effects omitted by reduced models become consequential. Assumptions required for analytic tractability then…

Human Cardiac Measurements with Diamond Magnetometers
Muhib Omar, Magnus Benke, Shaowen Zhang +27
We demonstrate direct, non-invasive and non-contact detection of human cardiac magnetic signals using quantum sensors based on nitrogen-vacancy (NV) centers in diamond. Three confi…

Blueprint for Diamond Magnetometry: Unraveling Quantum Dephasing of Nitrogen-Vacancy Center Ensembles in Diamond
Jixing Zhang, Cheuk Kit Cheung, Michael Kuebler +15
Diamonds with nitrogen-vacancy (NV) center ensembles are one of the most promising solid-state quantum platforms for various sensing applications. The combination of a long spin de…
