Building Bulk Geometry from the Tensor Radon Transform
ChunJun Cao, Xiao-Liang Qi, Brian Swingle +1
Using the tensor Radon transform and related numerical methods, we study how bulk geometries can be explicitly reconstructed from boundary entanglement entropies in the specific ca…
An efficient decoder for a linear distance quantum LDPC code
Shouzhen Gu, Christopher A. Pattison, Eugene Tang
Recent developments have shown the existence of quantum low-density parity check (qLDPC) codes with constant rate and linear distance. A natural question concerns the efficient dec…
The QAOA gets stuck starting from a good classical string
Madelyn Cain, Edward Farhi, Sam Gutmann +2
The Quantum Approximate Optimization Algorithm (QAOA) is designed to maximize a cost function over bit strings. While the initial state is traditionally a uniform superposition ove…
Efficient Soft-Output Guessing for Enhanced Quantum Tanner Code Decoding
Lukas Rapp, Muriel Médard, Eugene Tang +1
We introduce a generalized low-density parity-check decoding framework for quantum Tanner codes utilizing soft-output guessing random additive noise decoding (SOGRAND). By soft-out…
Layer codes as partially self-correcting quantum memories
Shouzhen Gu, Libor Caha, Shin Ho Choe +3
We investigate layer codes, a family of three-dimensional stabilizer codes that can achieve optimal scaling of code parameters and a polynomial energy barrier, as candidates for se…
Integration by differentiation: new proofs, methods and examples
Ding Jia, Eugene Tang, Achim Kempf
Recently, new methods were introduced which allow one to solve ordinary integrals by performing only derivatives. These studies were originally motivated by the difficulties of the…
