Measurement-and Feedback-Driven Non-Equilibrium Phase Transitions on a Quantum Processor
Zhiyi Wu, Xuandong Sun, Songlei Wang +8
Mid-circuit measurements and feedback operations conditioned on the measurement outcomes are essential for implementing quantum error-correction on quantum hardware. When integrate…
Magic transition in monitored free fermion dynamics
Cheng Wang, Zhi-Cheng Yang, Tianci Zhou +1
We investigate magic and its connection to entanglement in 1+1 dimensional random free fermion circuits, with a focus on hybrid free fermion dynamics that can exhibit an entangleme…
Exponentially slow thermalization in 1D fragmented dynamics
Cheng Wang, Shankar Balasubramanian, Yiqiu Han +3
We investigate the thermalization dynamics of 1D systems with local constraints coupled to an infinite temperature bath at one boundary. The coupling to the bath eventually erases…
Freezing transition in particle-conserving East model
Cheng Wang, Zhi-Cheng Yang
Quantum kinetically constrained models can exhibit a wealth of dynamical phenomena ranging from anomalous transport to Hilbert-space fragmentation (HSF). We study a class of one-di…
Free fermions under adaptive quantum dynamics
Vikram Ravindranath, Zhi-Cheng Yang, Xiao Chen
We study free fermion systems under adaptive quantum dynamics consisting of unitary gates and projective measurements followed by corrective unitary operations. We further introduc…
Entanglement Steering in Adaptive Circuits with Feedback
Vikram Ravindranath, Yiqiu Han, Zhi-Cheng Yang +1
The intensely studied measurement-induced entanglement phase transition has become a hallmark of non-unitary quantum many-body dynamics. Usually, such a transition only shows up at…
Entanglement phase transitions in random stabilizer tensor networks
Zhi-Cheng Yang, Yaodong Li, Matthew P. A. Fisher +1
We explore a class of random tensor network models with "stabilizer" local tensors which we name Random Stabilizer Tensor Networks (RSTNs). For RSTNs defined on a two-dimensional s…
Yang-Lee edge singularity triggered entanglement transition
Shao-Kai Jian, Zhi-Cheng Yang, Zhen Bi +1
We show that a class of symmetric non-Hermitian Hamiltonians realizing the Yang-Lee edge singularity exhibits an entanglement transition in the long-time steady stat…
