Tri-unitary quantum circuits
Cheryne Jonay, Vedika Khemani, Matteo Ippoliti
We introduce a novel class of quantum circuits that are unitary along three distinct "arrows of time". These dynamics share some of the analytical tractability of "dual-unitary" ci…

Ultrafast Variational Simulation of Non-trivial Quantum States with Long Range Interactions
Wen Wei Ho, Cheryne Jonay, Timothy H. Hsieh
State preparation protocols ideally require as minimal operations as possible, in order to be implemented in near-term, potentially noisy quantum devices. Motivated by long range i…

Coarse-grained dynamics of operator and state entanglement
Cheryne Jonay, David A. Huse, Adam Nahum
We give a detailed theory for the leading coarse-grained dynamics of entanglement entropy of states and of operators in generic short-range interacting quantum many-body systems. T…
