Quantum Key Distribution Based on Orthogonal State Encoding

Quantum key distribution(QKD) is one of the most significant areas in quantum information theory. For nearly four decades, substantial QKD schemes are developed. In early years, security protocols depend on switching different bases, namely based non-orthogonal state encoding. The famous example BB84 protocol. Later, other techniques were developed for orthogonal Examples such include GV protocol and order-rearrangement protocols. this paper, we present two One them does not need to employ while needs to. We provide analyses them, demonstrating that they highly efficient when considering consumptions both qubits classical bits. Furthermore, employment maximally entangled states could be less than previous ones so measurement efficiency increased. also modify implementing noisy channels by applying testing method.
