Maximally Extendable Product Codes are Good Coboundary Expanders

Gleb Kalachev, Pavel Panteleev

We investigate the coboundary expansion property of tensor product codes, known as product expansion, which plays an important role in recent constructions of good quantum LDPC cod…

Maximally Extendable Sheaf Codes

Pavel Panteleev, Gleb Kalachev

We study sheaf codes, a type of linear codes with a fixed hierarchical collection of local codes, viewed as a sheaf of vector spaces on a finite topological space we call coded spa…

Two-sided Robustly Testable Codes

Gleb Kalachev, Pavel Panteleev

We show that the tensor product of two random linear codes is robustly testable with high probability. This implies that one can obtain pairs of linear codes such that their produc…

Classical Sampling of Random Quantum Circuits with Bounded Fidelity

Gleb Kalachev, Pavel Panteleev, PengFei Zhou +1

Random circuit sampling has become a popular means for demonstrating the superiority of quantum computers over classical supercomputers. While quantum chips are evolving rapidly, c…

Asymptotically Good Quantum and Locally Testable Classical LDPC Codes

Pavel Panteleev, Gleb Kalachev

We study classical and quantum LDPC codes of constant rate obtained by the lifted product construction over non-abelian groups. We show that the obtained families of quantum LDPC c…

Multi-Tensor Contraction for XEB Verification of Quantum Circuits

Gleb Kalachev, Pavel Panteleev, Man-Hong Yung

The computational advantage of noisy quantum computers has been demonstrated by sampling the bitstrings of quantum random circuits. An important issue is how the performance of qua…

Degenerate Quantum LDPC Codes With Good Finite Length Performance

Pavel Panteleev, Gleb Kalachev

We study the performance of medium-length quantum LDPC (QLDPC) codes in the depolarizing channel. Only degenerate codes with the maximal stabilizer weight much smaller than their m…
