Stability of classical shadows under gate-dependent noise
Raphael Brieger, Markus Heinrich, Ingo Roth +1
Expectation values of observables are routinely estimated using so-called classical shadows$\unicode{x2014}$the outcomes of randomized bases measurements on a repeatedly prepared q…
Time-optimal multi-qubit gates: Complexity, efficient heuristic and gate-time bounds
Pascal Baßler, Markus Heinrich, Martin Kliesch
Multi-qubit entangling interactions arise naturally in several quantum computing platforms and promise advantages over traditional two-qubit gates. In particular, a fixed multi-qub…
Guaranteed efficient energy estimation of quantum many-body Hamiltonians using ShadowGrouping
Alexander Gresch, Martin Kliesch
Estimation of the energy of quantum many-body systems is a paradigmatic task in various research fields. In particular, efficient energy estimation may be crucial in achieving a qu…
