Error Correcting Codes with Machine Learning


Error correction codes (ECC) protect information from the noisy environment. ECC is essential part of the digital communications and used in countless real world applications. CoCoA studies theoretical aspect of the advanced ECC like low density parity check and polar codes. We also develop machine learning based ECC for almost zero error applications like NAND flash memory.

Quantum Error Correction Codes with Machine Learning

The main obstacle to construction of a quantum computer is the unavoidable presence of errors which disturb quantum information. Quantum error correction codes (QECC) are one of the ways to protect the state of the qubit. QECC will, therefore, be essential to perform meaningful quantum computation. CoCoA studies topological QECC considering actual implementation.
