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…
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…
Blockwise Post-processing in Satellite-based Quantum Key Distribution
Minu J. Bae, Nitish K. Panigrahy, Prajit Dhara +5
Free-space satellite communication has significantly lower photon loss than terrestrial communication via optical fibers. Satellite-based quantum key distribution (QKD) leverages t…
