- Abstract: In this paper, we utilize the potential offered by multidimensional separable
states (MSS) for secure and simultaneous distributions of keys in a layered
network. We present protocols for both quantum and semi-quantum key
distribution and discuss their robustness against various eavesdropping
strategies. We provide a procedure to identify the requisite resource states to
generalise these protocols for arbitrary layered networks. Finally, we study
the interrelation between the local dimensionalities of states and achievable
key rates in a given layer. These proposals are realisable with current
technology, thanks to employment of MSS and many advances in generation,
manipulation and measurement of higher-dimensional orbital angular momentum
states of light.

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.

In particular, we illustrate a possible photonic implementation where the information is encoded in the orbital angular momentum and polarization degrees of freedom of single photons.
