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…
