O-Sensing: Operator Sensing for Interaction Geometry and Symmetries
Meng Ye-Ming, Shi Zhe-Yu
We ask whether the Hamiltonian, interaction geometry, and symmetries of a quantum many-body system can be inferred from a few low-lying eigenstates without knowing which sites inte…

Enhanced measurements on quantum computers via the simultaneous probing of non-commuting Pauli operators
Rick P. A. Simon, Zheng Shi, Charlie Nation +2
Measuring the state of quantum computers is a highly non-trivial task, with implications for virtually all quantum algorithms. We propose a novel scheme where identical copies of a…
