• Abstract: We discuss protocols for quantum position verification schemes based on the standard quantum cryptographic assumption that a tagging device can keep classical data secure [Kent, 2011]. Our schemes use a classical key replenished by quantum key distribution. The position verification requires no quantum communication or quantum information processing. The security of classical data makes the schemes secure against non-local spoofing attacks that apply to schemes that do not use secure tags. The schemes are practical with current technology and allow for errors and losses. We describe how a proof-of-principle demonstration might be carried out.

• Classical-Quantum Dual Encoding for Laser Communications in Space [0.8972186395640676]
  In typical laser communications classical information is encoded by modulating the amplitude of the laser beam and measured via direct detection. We consider a simultaneous classical-quantum communication scheme where the classical information is encoded in the usual way and the quantum information is encoded as fluctuations of a sub-Poissonian noise-floor.

  We derive linear and nonlinear Bell-like inequalities for networks, whose violation certifies the absence of a minimum number of classical sources in them. We insert this assumption, which leads to results more amenable to certification in experiments.

  Quantum key distribution (QKD) offers theoretical security based on the laws of physics. We present a novel approach to eavesdropper location that can be employed in quantum as well as classical channels. We demonstrate that our approach outperforms conventional OTDR in the task of localizing an evanescent outcoupling of 1% with cm precision inside standard optical fibers.

  We introduce the idea of encrypting classical communication related to error-correction in order to decrease the amount of information available to the eavesdropper. We analyze the applicability of the method in the context of additional assumptions concerning the eavesdropper's quantum memory coherence time.

• 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.

  We consider the setting where the two parties (a classical Alice and a quantum Bob) can communicate only via a classical channel. We show that it is in general impossible to realize a two-party quantum functionality with black-box simulation in the case of malicious quantum adversaries. We provide a compiler that takes as input a classical proof of quantum knowledge (PoQK) protocol for a QMA relation R and outputs a zero-knowledge PoQK for R that can be verified by classical parties.

  Noise in quantum information processing is often viewed as a disruptive and difficult-to-avoid feature, especially in near-term quantum technologies. We show that by taking advantage of depolarisation noise in quantum circuits for classification, a robustness bound against adversaries can be derived. This is the first quantum protocol that can be used against the most general adversaries.
