Extensive long-range magic in non-Abelian topological orders
Yuzhen Zhang, Isaac H. Kim, Yimu Bao +1
We show that the low-energy states of non-Abelian topological orders possess extensive magic which is long-ranged, and cannot be eliminated by a constant-depth local unitary circui…
Non-linear Sigma Model for the Surface Code with Coherent Errors
Stephen W. Yan, Yimu Bao, Sagar Vijay
The surface code is a promising platform for a quantum memory, but its threshold under coherent errors remains incompletely understood. We study maximum-likelihood decoding of the…
Information dynamics and symmetry breaking in generic monitored -symmetric open quantum systems
Jacob Hauser, Ali Lavasani, Sagar Vijay +1
We investigate the steady-state phases of generic -symmetric monitored, open quantum dynamics. We describe the phases systematically in terms of both information-theo…
Dissipative Dynamical Phase Transition as a Complex Ising Model
Stephen W. Yan, Diego Barberena, Matthew P. A. Fisher +1
We investigate a quantum dynamical phase transition induced by the competition between local unitary evolution and dissipation in a qubit chain with a strong, on-site $\mathbb{Z}_2…
Persistent Topological Negativity in a High-Temperature Mixed-State
Yonna Kim, Ali Lavasani, Sagar Vijay
We study the entanglement structure of the Greenberger-Horne-Zeilinger (GHZ) state as it thermalizes under a strongly-symmetric quantum channel describing the Metropolis-Hastings d…
The Stability of Gapped Quantum Matter and Error-Correction with Adiabatic Noise
Ali Lavasani, Sagar Vijay
The codespace of a quantum error-correcting code can often be identified with the degenerate ground-space within a gapped phase of quantum matter. We argue that the stability of su…
Spontaneous localization at a potential saddle point from edge state reconstruction in a quantum Hall point contact
Liam A. Cohen, Noah L. Samuelson, Taige Wang +7
Quantum point contacts (QPCs) are an essential component in mesoscopic devices. Here, we study the transmission of quantum Hall edge modes through a gate-defined QPC in monolayer g…
Geometric phases in generalized radical Floquet dynamics
Brenden Roberts, Sagar Vijay, Arpit Dua
The Pancharatnam phase is a generalization of the Berry phase that applies to discrete sequences of quantum states. Here, we show that the Pancharatnam phase is a natural invariant…
