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…
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…
Experimental signatures of Hilbert-space ergodicity: Universal bitstring distributions and applications in noise learning
Adam L. Shaw, Daniel K. Mark, Joonhee Choi +4
Systems reaching thermal equilibrium are ubiquitous. For classical systems, this phenomenon is typically understood statistically through ergodicity in phase space, but translating…
