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…
Observation of ballistic plasma and memory in high-energy gauge theory dynamics
Daniel K. Mark, Federica M. Surace, Thomas Schuster +4
Gauge theories describe the fundamental forces of nature. However, high-energy dynamics, such as the formation of quark-gluon plasmas, is notoriously difficult to model with classi…
How much can we learn from quantum random circuit sampling?
Tudor Manole, Daniel K. Mark, Wenjie Gong +3
Benchmarking quantum devices is a foundational task for the sustained development of quantum technologies. However, accurate in situ characterization of large-scale quantum devices…
Robust and Parallel Control of Many Qubits
Wenjie Gong, Soonwon Choi
The rapid growth in size of quantum devices demands efficient ways to control them, which is challenging for systems with thousands of qubits or more. Here, we present a simple yet…
