Quantum computers require memories that are capable of storing quantum information reliably for long periods of time. The surface code is a two-dimensional quantum memory …
A bstract We initiate a study of subregion dualities, entropy, and redundant encoding of bulk points in holographic theories deformed by\(T\overline {T}\) and its generalizations. This …
A bstract We reconsider the black hole firewall puzzle, emphasizing that quantum error- correction, computational complexity, and pseudorandomness are crucial concepts for …
Some form of quantum error correction is necessary to produce large-scale fault-tolerant quantum computers and finds broad relevance in physics. Most studies customarily assume …

For quantum error-correcting codes to be realizable, it is important that the qubits subject to the code constraints exhibit some form of limited connectivity. The works of Bravyi and …

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 …
Almheiri, Dong, and Harlow [J. High Energy Phys. 04 (2015) 163. JHEPFG 1029-8479 10.1007/JHEP04 (2015) 163] proposed a highly illuminating connection between the …

We prove that any one-dimensional (1D) quantum state with small quantum conditional mutual information in all certain tripartite splits of the system, which we call a quantum …
We introduce a new quantity that we term recoverable information, defined for stabilizer Hamiltonians. For such models, the recoverable information provides a measure of the …
