  Project-1: Error Correction in Quantum Key Distribution using LDPC codes.1. Designed an algorithm to find the parity check matrix needed to generate syndrome.2. Designed a complete interface to handle error correction (encoding and decoding) in a binary symmetric channel with different error rates.3. Studied error correction using LDPC codes.Project-2: Privacy Amplification in Quantum Key Distribution.1. Designed a Toeplitz matrix as a universal hash function.2. Extracted a secret key from a weak secure key (key generated after error correction) using FFT technique. Show less

  Primary Project: Error Correction in Quantum Key Distribution using Polar Codes:1. Developed an algorithm to find the reliability sequence required to do encoding for arbitrarily long block length in a binary discrete memory-less channel.2. Implemented encoding of polar codes using the generated reliability sequence.3. Implemented decoding of polar codes using successive-cancellation decoding method.4. Calculated the entropy loss and extractable key length.5. Studied the working and design of polar codes.6. Worked with high-performance computer clusters.Project 2: Implementation of LDPC Error Correction over Experimental QKD Dataset1. Implemented LDPC encoding using IEEE standard parity check matrix.2. Implemented LDPC decoding using the Belief Propagation algorithm on the Quantum Key Distribution data set. Show less
