New Security Proof of a Restricted High-Dimensional QKD Protocol
Hasan Iqbal, Walter O. Krawec
High-dimensional (HD) states are known to have several interesting properties when applied to quantum cryptography. For quantum key distribution (QKD), these states have the potent…
Analysis of a High-Dimensional Extended B92 Protocol
Hasan Iqbal, Walter O. Krawec
Quantum key distribution (QKD) allows two parties to establish a shared secret key that is secure against all-powerful adversaries. One such protocol named B92 is quite appealing d…
Semi-Quantum Cryptography
Hasan Iqbal, Walter O. Krawec
Semi-quantum communication, a model introduced in 2007 by M. Boyer, D. Kenigsberg, and T. Mor (PRL 99 140501), involves the use of fully-quantum users and semi-quantum, or "classic…
High-Dimensional Semi-Quantum Cryptography
Hasan Iqbal, Walter O. Krawec
A semi-quantum key distribution (SQKD) protocol allows two users, one of whom is restricted in their quantum capabilities, to establish a shared secret key, secure against an all-p…
From Classical to Semi-Quantum Secure Communication
Allison Gagliano, Walter O. Krawec, Hasan Iqbal
In this work we introduce a novel QKD protocol capable of smoothly transitioning, via user-tuneable parameter, from classical to semi-quantum in order to help understand the effect…
