Operator relaxation and the optimal depth of classical shadows
Matteo Ippoliti, Yaodong Li, Tibor Rakovszky +1
Classical shadows are a powerful method for learning many properties of quantum states in a sample-efficient manner, by making use of randomized measurements. Here we study the sam…
Slow thermalization and subdiffusion in conserving Floquet random circuits
Cheryne Jonay, Joaquin F. Rodriguez-Nieva, Vedika Khemani
Random quantum circuits are paradigmatic models of minimally structured and analytically tractable chaotic dynamics. We study a family of Floquet unitary circuits with Haar random…
Random Quantum Circuits
Matthew P. A. Fisher, Vedika Khemani, Adam Nahum +1
Quantum circuits -- built from local unitary gates and local measurements -- are a new playground for quantum many-body physics and a tractable setting to explore universal collect…
Topology, criticality, and dynamically generated qubits in a stochastic measurement-only Kitaev model
Adithya Sriram, Tibor Rakovszky, Vedika Khemani +1
We consider a paradigmatic solvable model of topological order in two dimensions, Kitaev's honeycomb Hamiltonian, and turn it into a measurement-only dynamics consisting of stochas…
