Quantum Codes Whop On a quest for fault tolerant quantum error correction? explore how quantum product codes (qpcs) revolutionize data integrity and scalability in quantum computing. Product code described in section 1. for this code, the objects we care about are.
Quantum Product Codes Quantumexplainer In this manuscript we explain how to construct families of quantum codes with exceptional asymptotic properties in an explicit and highly symmetrical way. to this end, we mimic the well known balanced product x y of two topological h spaces x and y which admit the action of a group h [11]. Ldpc css codes is a class of quantum error correcting codes, and a long standing open problem was to construct such codes with distance as close to the number of qubits, n, as possible. The generalized hypergraph product is defined in "degenerate quantum ldpc codes with good finite length performance". the bias tailored lifted product is defined in "bias tailored quantum ldpc codes". Examples of quantum ldpc codes. lecture 2: slides, p roblem set, video. content: lecture 3: slides, problem set, video. content: lecture 4: slides, problem set, video. content: main page.

Two bipartite expander graphs can be used to construct a quantum css code (the quantum expander code) by using the parity check matrix of one as x checks, and the parity check matrix of the other as z checks. We study a three fold variant of the hypergraph product code construction, differing from the standard homological product of three classical codes. when instantiated with 3 classical ldpc codes, this "xyz product" yields a non css quantum ldpc code which might display a large minimum distance. The qbp unifies diverse code families, including hypergraph product codes of any dimension and fracton codes like the x cube model, revealing deeper connections between topological quantum codes and foliated fracton order theories. In this paper we introduce a new product code construction which is a natural generalization of classical product codes to quantum codes: starting from a set of component.
