Preparing random states and benchmarking with many-body quantum chaos

2021 · arXiv (Cornell University)

Producing quantum states at random has become increasingly important in modern quantum science, with applications both theoretical and practical. In particular, ensembles of such randomly-distributed, but pure, quantum states underly our understanding of complexity in …

Derandomized shallow shadows: Efficient Pauli learning with bounded-depth circuits

2024 · arXiv (Cornell University)

Efficiently estimating large numbers of non-commuting observables is an important subroutine of many quantum science tasks. We present the derandomized shallow shadows (DSS) algorithm for efficiently learning a large set of non-commuting observables, using shallow …
