- Abstract: In recent times, secure quantum communication in layered networks has emerged
as an important area of study. In this paper, we harness the potential offered
by multidimensional states in secure quantum communication with only one
quantum participant and all the other classical participants. We propose three
protocols for (i) entanglement-based layered semi--quantum key distribution,
(ii) layered semi-quantum secret sharing, and, (iii) integrated layered
semi-quantum key distribution and secret sharing to share secret information in
an arbitrarily layered network. These protocols integrate the features of semi
quantum communication in layered networks. All three protocols allow for the
simultaneous distribution of secure information in all the layers of a network,
thanks to the employment of multidimensional states. We present these protocols
for a small network of at most five participants and three layers and show the
robustness of the same against various eavesdropping strategies. Finally, we
provide a detailed procedure for the generalization of the proposed protocols
to distribute keys/secrets in any arbitrarily structured quantum network.

There are two primary approaches to achieving quantum-resistant security: quantum key distribution (QKD) and post-quantum cryptography (PQC)
We introduce the pros and cons of these protocols and explore how they can be combined to achieve a higher level of security and/or improved performance in key distribution.
We hope our discussion inspires further research into the design of hybrid cryptographic protocols for quantum-classical communication networks.
