Two-dimensional Entanglement-assisted Quantum Quasi-cyclic Low-density Parity-check Codes

Pavan Kumar, Shayan Srinivasa Garani

For any positive integer $g \geq 2$ , we derive general condition for the existence of a $2 g$ -cycle in the Tanner graph of two-dimensional ( $2$ -D) classical quasi-cyclic (QC) low-den…

Entanglement-assisted Quasi-cyclic Quantum Low-density Parity-check Codes over Qubits

Pavan Kumar, Abhi Kumar Sharma, Karthik Bharadwaj +1

We construct several families of entanglement-assisted quasi-cyclic quantum LDPC (EA-QC-QLDPC) codes via structured tilings of permutation matrices. The entanglement-unassisted por…
