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…

Fault-Tolerant Quantum LDPC Encoders
Abhi Kumar Sharma, Shayan Srinivasa Garani
We propose fault-tolerant encoders for quantum low-density parity check (LDPC) codes. By grouping qubits within a quantum code over contiguous blocks and applying preshared entangl…
