Fully Quantum Computational Entropies
Noam Avidan, Thomas A. Hahn, Joseph M. Renes +1
Quantum information theory, particularly its entropic formulations, has made remarkable strides in characterizing quantum systems and tasks. However, a critical dimension remains u…
Efficient and optimal quantum state discrimination via quantum belief propagation
Christophe Piveteau, Joseph M. Renes
We present an efficient quantum algorithm for a structured state discrimination problem we call the subspace decoding task. Building on this, we show that the algorithm enables eff…
Computation with quantum Reed-Muller codes and their mapping onto 2D atom arrays
Anqi Gong, Joseph M. Renes
We give a fault tolerant construction for error correction and computation using two punctured quantum Reed-Muller (PQRM) codes. In particular, we consider the self-…
Tensor Network Decoding Beyond 2D
Christophe Piveteau, Christopher T. Chubb, Joseph M. Renes
Decoding algorithms based on approximate tensor network contraction have proven tremendously successful in decoding 2D local quantum codes such as surface/toric codes and color cod…
