Abstract
Quantum Key Distribution (QKD) is used for generating key between two legitimate user Alice and Bob. In the past decade, QKD using qubit has been investigated for different cryptographic strategies. Analysis of qutrit photon states in QKD is theoretically investigated and different eavesdropping strategies have been discussed in this paper. Modified two stage Positive Operator Value Measurement (POVM) is used to determine the qutrit states. An expression for error rate in data transmission has been formulated both in case of entangled and opaque eavesdropping. A protocol for encryption of data in qutrit states in one-time-pad scheme is initiated to improve on information reconciliation. © Springer Nature Singapore Pte Ltd. 2017.
