Efficient High-dimensional Quantum Key Distribution with Hybrid Encoding
We propose a schematic setup of quantum key distribution (QKD) with an
improved secret key rate based on high-dimensional quantum states. Two
degrees-of-freedom of a single photon, orbital angular momentum modes, and
multi-path modes, are used to encode secret key information. Its practical
implementation consists of optical elements that are within the reach of
current technologies such as a multiport interferometer. We show that the
proposed feasible protocol has improved the secret key rate with much
sophistication compared to the previous 2-dimensional protocol known as the
detector-device-independent QKD.Comment: 10 pages, 6 figure
