Researchers at PNSI lab led by Prof. Garani are actively involved in the broad areas of research within quantum error correction. In a recent breakthrough work, Nadkarni and Garani demonstrated how a useful quantum code can be constructed from zero-rate entanglement-assisted CSS codes .
Demonstration of coding analog of superadditivity :
Codes C1[3,1,3] and C2[3,1,3] are over Galois fields F2 and F4. These two codes yield zero-rate entanglement-assisted CSS codes since the number of logical qudits is zero. The tensor product of these codes yields a useful quantum code of rate 1/3, demonstrating coding analog of superadditivity.
Also, the authors in  have proposed a novel photonic architecture of such entanglement-assisted binary quantum tensor product codes within a quantum transceiver system .
