Abstract
3-pulse DPS-QKD offers enhanced security compared to conventional DPS-QKD by decreasing the learning rate of an eavesdropper and unmasking her presence with an increased error rate upon application of intercept and resend attack. The probability of getting one bit of sifted key information using beamsplitter attack also reduces by 25% in our implentation compared to normal DPS.
