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…
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…
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…
New Key Rate Bound for High-Dimensional BB84 with Multiple Basis Measurements
Trevor N. Thomas, Walter O. Krawec
In this paper we derive a new bound on the secret key-rate of the High Dimensional BB84 protocol operating with multiple mutually unbiased bases (MUBs). To our knowledge, our proof…
Quantum Conference Key Agreement with Classical Advantage Distillation
Walter O. Krawec
In this work, we prove security of a quantum conference key agreement (QCKA) protocol augmented with a classical advantage distillation (CAD) protocol. We derive a proof of securit…
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…
