Full Counting Statistics across the Entanglement Phase Transition of Non-Hermitian Hamiltonians with Charge Conservations
Tian-Gang Zhou, Yi-Neng Zhou, Pengfei Zhang
Performing quantum measurements produces not only the expectation value of a physical observable but also the probability distribution of all possible outcomes . The…
Temporal Entanglement in Chaotic Quantum Circuits
Alessandro Foligno, Tianci Zhou, Bruno Bertini
The concept of space-evolution (or space-time duality) has emerged as a promising approach for studying quantum dynamics. The basic idea involves exchanging the roles of space and…
Maximal entanglement velocity implies dual unitarity
Tianci Zhou, Aram W. Harrow
A global quantum quench can be modeled by a quantum circuit with local unitary gates. In general, entanglement grows linearly at a rate given by entanglement velocity, which is upp…
Measurement induced entanglement transition in two dimensional shallow circuit
Hanchen Liu, Tianci Zhou, Xiao Chen
We prepare two dimensional states generated by shallow circuits composed of (1) one layer of two-qubit CZ gate or (2) a few layers of two-qubit random Clifford gate. After measurin…
Operator Growth from Global Out-of-time-order Correlators
Tianci Zhou, Brian Swingle
In the context of chaotic quantum many-body systems, we show that operator growth, as diagnosed by out-of-time-order correlators of local operators, also leaves a sharp imprint in…
Non-unitary Entanglement Dynamics in Continuous Variable Systems
Tianci Zhou, Xiao Chen
We construct a random unitary Gaussian circuit for continuous-variable (CV) systems subject to Gaussian measurements. We show that when the measurement rate is nonzero, the steady…
