Symmetry-Accelerated Classical Simulation of Clifford-Dominated Circuits
Giulio Camillo, Filipa C. R. Peres, Markus Heinrich +1
Classical simulation of quantum circuits plays a crucial role in validating quantum hardware and delineating the boundaries of quantum advantage. Among the most effective simulatio…

Anti-concentration is (almost) all you need
Markus Heinrich, Jonas Haferkamp, Ingo Roth +1
Until very recently, it was generally believed that the (approximate) 2-design property is strictly stronger than anticoncentration of random quantum circuits, mainly because it wa…

Will it glue? On short-depth designs beyond the unitary group
Lorenzo Grevink, Jonas Haferkamp, Markus Heinrich +4
We study the formation of short-depth designs beyond the unitary group. We provide a range of results on several groups of broad interest in quantum information science: the Cliffo…
