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 …

Unitary designs in nearly optimal depth
2025 · arXiv (Cornell University)
We construct $\varepsilon$-approximate unitary $k$-designs on $n$ qubits in circuit depth $O(\log k \log \log n k / \varepsilon)$. The depth is exponentially improved over all known results in all three parameters $n$, $k$, $\varepsilon$. …
