Characterizing a non-equilibrium phase transition on a quantum computer
Eli Chertkov, Zihan Cheng, Andrew C. Potter +13
At transitions between phases of matter, physical systems can exhibit universal behavior independent of their microscopic details. Probing such behavior in quantum many-body system…
Bulk-boundary correspondence for intrinsically-gapless SPTs from group cohomology
Rui Wen, Andrew C. Potter
Intrinsically gapless symmetry protected topological phases (igSPT) are gapless systems with SPT edge states with properties that could not arise in a gapped system with the same s…
Transitions in the learnability of global charges from local measurements
Fergus Barratt, Utkarsh Agrawal, Andrew C. Potter +2
We consider monitored quantum systems with a global conserved charge, and ask how efficiently an observer ("eavesdropper") can learn the global charge of such systems from local pr…
A matrix product operator approach to non-equilibrium Floquet steady states
Zihan Cheng, Andrew C. Potter
We present a numerical method to simulate non-equilibrium Floquet steady states of one-dimensional periodically-driven (Floquet) many-body systems coupled to a dissipative bath, ca…
Qubit-efficient simulation of thermal states with quantum tensor networks
Yuxuan Zhang, Shahin Jahanbani, Daoheng Niu +2
We present a holographic quantum simulation algorithm to variationally prepare thermal states of -dimensional interacting quantum many-body systems, using only enough hardware q…
Holographic quantum simulation of entanglement renormalization circuits
Sajant Anand, Johannes Hauschild, Yuxuan Zhang +2
While standard approaches to quantum simulation require a number of qubits proportional to the number of simulated particles, current noisy quantum computers are limited to tens of…
