Speaker : Dr. Tushar Bag

Title of the Talk : From Bits to Qubits: A Journey into Quantum Error Correction with Algebraic Codes

Date, Time and venue : 13 March 2025, 3:30 PM - 4:30 PM at Seminar Hall, Dept of Mathematics.

Abstract : Reliable error correction is crucial for the development of quantum computing. This talk will provide an overview of both classical and quantum coding theory, laying the foundation for quantum error correction. We will explore how techniques from classical coding—particularly linear codes—can be adapted to protect fragile quantum states. Additionally, I will discuss the construction of quantum codes using various families of linear codes, including cyclic, skew-cyclic, quasi-cyclic, and group ring codes. Special emphasis will be placed on the advantages of skew-cyclic codes over traditional cyclic codes, along with some of my newly constructed binary and non-binary quantum codes.
