Random insights into the complexity of two-dimensional tensor network calculations
Sofia Gonzalez-Garcia, Shengqi Sang, Timothy H. Hsieh +4
Projected entangled pair states (PEPS) offer memory-efficient representations of some quantum many-body states that obey an entanglement area law, and are the basis for classical s…
Measurement-induced phase transitions in the toric code
Amir-Reza Negari, Subhayan Sahu, Timothy H. Hsieh
We show how distinct phases of matter can be generated by performing random single-qubit measurements on a subsystem of toric code. Using a parton construction, such measurements m…
Mixed-state long-range order and criticality from measurement and feedback
Tsung-Cheng Lu, Zhehao Zhang, Sagar Vijay +1
We propose a general framework for using local measurements, local unitaries, and non-local classical communication to construct quantum channels which can efficiently prepare mixe…
Experimental demonstration of the advantage of adaptive quantum circuits
Michael Foss-Feig, Arkin Tikku, Tsung-Cheng Lu +16
Adaptive quantum circuits employ unitary gates assisted by mid-circuit measurement, classical computation on the measurement outcome, and the conditional application of future unit…
Channeling quantum criticality
Yijian Zou, Shengqi Sang, Timothy H. Hsieh
We analyze the effect of decoherence, modelled by local quantum channels, on quantum critical states and we find universal properties of the resulting mixed state's entanglement, b…
Ultrafast Entanglement Dynamics in Monitored Quantum Circuits
Shengqi Sang, Zhi Li, Timothy H. Hsieh +1
Projective measurement, a basic operation in quantum mechanics, can induce seemingly nonlocal effects. In this work, we analyze such effects in many-body systems by studying the no…
