Gate Parameter Lee-Yang Zeros and Dynamical Phases in Quantum Circuits
Chang Liu, Yu Wu, Yunfeng Jiang +1
We propose gate-parameter Lee-Yang zeros of Loschmidt amplitudes as probes of dynamical phases in finite quantum circuits. We illustrate this approach using a brickwork model, wher…

All Giant Graviton Two-Point Functions at Two-Loops
Yu Wu, Yunfeng Jiang, Chang Liu +1
We present a comprehensive two-loop computation of correlation functions involving two maximal giant gravitons and two arbitrary -charge single-trace half-BPS operators in $\mat…

Exact Spin Correlators of Integrable Quantum Circuits from Algebraic Geometry
Arthur Hutsalyuk, Yunfeng Jiang, Balazs Pozsgay +2
We calculate the correlation functions of strings of spin operators for integrable quantum circuits exactly. These observables can be used for calibration of quantum simulation pla…
