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…
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…
