Perturbative framework for engineering arbitrary Floquet Hamiltonian

Yingdan Xu, Lingzhen Guo·Oct 14, 2024

We develop a systematic perturbative framework to engineer an arbitrary target Hamiltonian in the Floquet phase space of a periodically driven oscillator based on Floquet–Magnus expansion. The high-order errors in the engineered Floquet Hamiltonian a...

How to Construct Random Unitaries

Fermi Ma, Hsin-Yuan Huang·Oct 14, 2024

The existence of pseudorandom unitaries (PRUs)—efficient quantum circuits that are computationally indistinguishable from Haar-random unitaries—has been a central open question, with significant implications for cryptography, complexity theory, and f...

Observable measurement-induced transitions

Aleksei Khindanov, I. Aleiner, L. Faoro +1 more·Oct 12, 2024

One of the main postulates of quantum mechanics is that measurements destroy quantum coherence (wave function collapse). Recently it was discovered that in a many-body system dilute local measurements still preserve some coherence across the entire s...

Disentangling magic states with classically simulable quantum circuits

Gerald E. Fux, Benjamin Béri, Rosario Fazio +1 more·Oct 11, 2024

We show that states obtained from deep random Clifford circuits doped with non-Clifford phase gates (including T-gates and $\sqrt{\mathrm{T}}$-gates) can be disentangled completely, provided the number of non-Clifford gates is smaller or approximatel...
