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…
Continuous symmetry breaking in adaptive quantum dynamics
Jacob Hauser, Yaodong Li, Sagar Vijay +1
Adaptive quantum circuits, in which unitary operations, measurements, and feedback are used to steer quantum many-body systems, provide an exciting opportunity to generate new dyna…
Quantum Coding Transitions in the Presence of Boundary Dissipation
Izabella Lovas, Utkarsh Agrawal, Sagar Vijay
We investigate phase transitions in the encoding of quantum information in a quantum many-body system due to the competing effects of unitary scrambling and boundary dissipation. S…
Monitored Quantum Dynamics and the Kitaev Spin Liquid
Ali Lavasani, Zhu-Xi Luo, Sagar Vijay
Quantum circuit dynamics with local projective measurements can realize a rich spectrum of entangled states of quantum matter. Motivated by the physics of the Kitaev quantum spin l…
Isotropic Layer Construction and Phase Diagram for Fracton Topological Phases
Sagar Vijay
Starting from an isotropic configuration of intersecting, two-dimensional toric codes, we construct a fracton topological phase introduced in Ref. [26], which is characterized by i…
Braiding without Braiding: Teleportation-Based Quantum Information Processing with Majorana Zero Modes
Sagar Vijay, Liang Fu
We present a new measurement-based scheme for performing braiding operations on Majorana zero modes and for detecting their non-Abelian statistics without moving or hybridizing the…
