• Abstract: We present a quantum multi-factor authentication mechanism based on the hidden-matching quantum communication complexity problem. It offers step-up graded authentication for users via a quantum token. In this paper, we outline the protocol, demonstrate that it can be used in a largely classical setting, explain how it can be implemented in SASL, and discuss arising security features. We also offer a comparison between our mechanism and current state-of-the-art multi-factor authentication mechanisms.

  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.

  The No-Free-Lunch (NFL) theorem quantifies problem- and data-independent generalization errors regardless of the optimization process. We categorize a diverse array of quantum learning algorithms into three learning protocols designed for learning quantum dynamics under a specified observable. Our derived NFL theorems demonstrate quadratic reductions in sample complexity across CLC-LPs, ReQu-LPs, and Qu-LPs. We attribute this performance discrepancy to the unique capacity of quantum-related learning protocols to indirectly utilize information concerning the global phases of non-orthogonal quantum states.

We demonstrate a general method to guarantee that certain correlations cannot be generated in a given quantum network.

• Experimental quantum key distribution certified by Bell's theorem [0.0]
  cryptographic key exchange protocols traditionally rely on computational conjectures to provide security against eavesdropping attacks. quantum key distribution protocols provide information-theoretic security against such attacks. However, quantum protocols are subject to a new class of attacks exploiting implementation defects in the physical devices involved. We present here the experimental realisation of a complete quantum key distribution protocol immune to these vulnerabilities.
