Robust Hamiltonian engineering with subensemble control
Wenjie Gong, Matteo Votto, Soonwon Choi
We present a robust protocol to reshape interactions in a spin ensemble based on global control pulse sequences applied to multiple subensembles in parallel. This setting arises na…

Robust multiparameter estimation using quantum scrambling
Wenjie Gong, Bingtian Ye, Daniel Mark +1
We propose and analyze a versatile and efficient multiparameter quantum sensing protocol, which simultaneously estimates many non-commuting and time-dependent signals that are cohe…

Rare-Event Quantum Sensing using Logical Qubits
Robert Ott, Torsten V. Zache, Soonwon Choi +2
We present a novel protocol to detect rare signals in a noisy environment using quantum error correction (QEC). The key feature of our protocol is the discrimination between signal…
