Finite Key Underwater Quantum Key Distribution: Performance Analysis and Improvements
Trevor Thomas, Michael Warnock, Sarah Previte +2
Quantum key distribution (QKD) allows for the establishment of a secret key between two parties, secure against computationally unbounded adversaries. Most experimental and theoret…
S-CAD: Selective Classical Advantage Distillation for Quantum Conference Key Agreement
Trevor Thomas, Walter O. Krawec, Bing Wang
Quantum conference key agreement (QCKA) protocols utilize GHZ states to establish shared group keys between multiple parties. While previous work has shown that standard Classical…
Finite Key Security of the Extended B92 Protocol
Walter O. Krawec
In this paper, we derive a new proof of security for the Extended B92 QKD protocol. We derive a general entropic uncertainty relation for QKD protocols with data filtering and reje…
Further Improving the Decoy State Quantum Key Distribution Protocol with Advantage Distillation
Walter O. Krawec
In this paper, we revisit the application of classical advantage distillation (CAD) to the decoy-state BB84 protocol. Prior work has shown that CAD can greatly improve maximal dist…
Opportunistic Scheduling for Single-downlink Satellite-based Quantum Key Distribution
Md Zakir Hossain, Nitish K. Panigrahy, Walter O. Krawec +2
Satellite-based quantum key distribution (QKD), leveraging low photon loss in free-space quantum communication, is widely regarded as one of the most promising directions to achiev…
Quantum Public Key Encryption for NISQ Devices
Nishant Rodrigues, Walter O. Krawec, Brad Lackey +2
Quantum public-key encryption (PKE), where public-keys and/or ciphertexts can be quantum states, is an important primitive in quantum cryptography. Unlike classical PKE (e.g., RSA…
