The Physics of (good) LDPC Codes I. Gauging and dualities
Tibor Rakovszky, Vedika Khemani
Low-depth parity check (LDPC) codes are a paradigm of error correction that allow for spatially non-local interactions between (qu)bits, while still enforcing that each (qu)bit int…
Learnability transitions in monitored quantum dynamics via eavesdropper's classical shadows
Matteo Ippoliti, Vedika Khemani
Monitored quantum dynamics -- unitary evolution interspersed with measurements -- has recently emerged as a rich domain for phase structure in quantum many-body systems away from e…
Prethermal stability of eigenstates under high frequency Floquet driving
Nicholas O'Dea, Fiona Burnell, Anushya Chandran +1
Systems subject to high-frequency driving exhibit Floquet prethermalization, that is, they heat exponentially slowly on a time scale that is large in the drive frequency, $τ_{\rm h…
Dynamics of magnetization at infinite temperature in a Heisenberg spin chain
Eliott Rosenberg, Trond Andersen, Rhine Samajdar +178
Understanding universal aspects of quantum dynamics is an unresolved problem in statistical mechanics. In particular, the spin dynamics of the 1D Heisenberg model were conjectured…
Quantum turnstiles for robust measurement of full counting statistics
Rhine Samajdar, Ewan McCulloch, Vedika Khemani +2
We present a scalable protocol for measuring full counting statistics (FCS) in experiments or tensor-network simulations. In this method, an ancilla in the middle of the system act…
Quantifying quantum chaos through microcanonical distributions of entanglement
Joaquin F. Rodriguez-Nieva, Cheryne Jonay, Vedika Khemani
A characteristic feature of "quantum chaotic" systems is that their eigenspectra and eigenstates display universal statistical properties described by random matrix theory (RMT). H…
Measurement-induced entanglement and teleportation on a noisy quantum processor
Jesse C. Hoke, Matteo Ippoliti, Eliott Rosenberg +160
Measurement has a special role in quantum theory: by collapsing the wavefunction it can enable phenomena such as teleportation and thereby alter the "arrow of time" that constrains…
