Quantum Message Passing Convergence and Vanishing Block-Error Probability for Random LDPC Codes

Avijit Mandal, Christophe Piveteau, Joseph M. Renes +1

Belief propagation with quantum messages (BPQM) is a quantum algorithm that decodes classical codes transmitted over classical--quantum channels. It realizes optimal decoding on tr…

Affine Filtering Measurements and Their Applications to Quantum Decoding

Avijit Mandal, Noah Shutty, Henry D. Pfister +1

Unambiguous state discrimination (USD) measurements are attractive because outcomes are either marked as conclusive (i.e., error free) or inconclusive (i.e., erased). We study affi…

Quantum Message Passing for Factor Graphs over Finite Abelian Groups

Avijit Mandal, Henry D. Pfister

We develop a quantum message-passing framework for factor graphs over finite abelian groups. Our starting point is the task of discriminating between a collection of quantum states…

Optimization Using Locally-Quantum Decoders

Noah Shutty, Avijit Mandal, Seyoon Ragavan +8

It was pointed out in [JSW+25] that widely-studied optimization problems such as D-regular max-k-XORSAT can be reduced to decoding of LDPC codes, using quantum algorithms related t…

Quantum State Compression with Polar Codes

Jack Weinberg, Avijit Mandal, Henry D. Pfister

In the quantum compression scheme proposed by Schumacher, Alice compresses a message that Bob decompresses. In that approach, there is some probability of failure and, even when su…
