# Saturation and recurrence of quantum complexity in random quantum circuits

@inproceedings{Oszmaniec2022SaturationAR, title={Saturation and recurrence of quantum complexity in random quantum circuits}, author={Michał Oszmaniec and Michal Horodecki and Nicholas Hunter-Jones}, year={2022} }

Quantum complexity is a measure of the minimal number of elementary operations required to approximately prepare a given state or unitary channel. Recently, this concept has found applica-tions beyond quantum computing—in studying the dynamics of quantum many-body systems and the long-time properties of AdS black holes. In this context Brown and Susskind [1] conjectured that the complexity of a chaotic quantum system grows linearly in time up to times exponential in the system size, saturating…

Entangling Power and Quantum Circuit Complexity.

This work discusses a simple relationship when both the entanglement of a state and the cost of a unitary take small values, building on ideas on how values of entangling power of quantum gates add up, and proposes a continuous-variable small incremental entangling bound.

Improved spectral gaps for random quantum circuits: Large local dimensions and all-to-all interactions

The smallest non-trivial case exactly is solved exactly and numerics and Knabe bounds are combined to improve the constants involved in the spectral gap for small values of $t$ and a recursion relation for the spectral gaps involving an auxiliary random walk is proved.

Decoupling with Random Quantum Circuits

It is proved that random quantum circuits with O(n log2n) gates satisfy an essentially optimal decoupling theorem and can be implemented in depth O(log3n), which proves that decoupled can happen in a time that scales polylogarithmically in the number of particles in the system.

It is shown that for almost any sufficiently long quantum circuit one can construct a black-box problem which is solved by the circuit with a constant number of quantum queries, but which requires exponentially many classical queries, even if the classical machine has the ability to postselect.
