Phase information beyond entanglement sudden death in coherence-to-entanglement conversion under post-gate noise
Asad Ali, Hashir Kuniyil, M. T Rahim +1
An ideal CNOT maps the phase of a coherent qubit onto the coherence between and of a two-qubit state, producing an output that carries both entanglement and e…
Analytic Benchmarks for Coherence-to-Entanglement Conversion under Post-Gate Noise in CNOT-Based Protocols
Asad Ali, H. Kuniyil, M. I. Hussain +3
Coherence-to-entanglement conversion transforms single-qubit superposition into a practical two-qubit resource, but noise limits this process in near-term quantum hardware. We deri…
Reservoir-independent lossless charging and protected storage of an open quantum battery
Asad Ali, H. Kuniyil, M. I Hussain +3
A quantum battery charged through a lossy intermediate state faces a structural trade-off between charging speed and dissipation. We show that an exact algebraic cancellation remov…
Counterdiabatic Raman Atom Optics for Compact High-Sensitivity Gravimetry
Asad Ali, Hamid Arian Zad, Saif Al-Kuwari +6
Large-momentum-transfer (LMT) atom interferometry provides a route toward enhanced inertial sensitivity in compact quantum sensors, but its scalability is limited by the accumulati…
High-dimensional coherence to entanglement transduction under canonical noise
Asad Ali, Aiham M. Rostom, Saif Al-Kuwari +3
We develop an analytical framework for coherence-to-entanglement conversion in bipartite high-dimensional quantum systems, so-called qunits. An arbitrary coherent input qunit is co…
Recovery-Induced Erasure Attack on QKD Systems
Hashir Kuniyil, Asad Ali, Syed M. Arslan +3
Detector dead time is typically treated as a fixed parameter in quantum key distribution (QKD) security analyses. In practice, however, the effective recovery time of single-photon…
One-Sided Device-Independent Quantum Key Distribution over Noisy Metropolitan Links: Noise Thresholds and Purification-Assisted Recovery
Syed M Arslan, Muhammad T Rahim, Asad Ali +2
One-sided device-independent quantum key distribution (1SDI-QKD) offers a practical middle ground between fully device-independent protocols and standard QKD, achieving security wi…
Quantum Repeater Chains via Cavity Magnon for Scalable Quantum Networks
Mughees Ahmed Khan, Syed Shahmir, Muhammad Talha Rahim +2
Scalable quantum networks require quantum repeaters to overcome major challenges such as photon loss and decoherence in long-distance quantum communication. In this paper, we prese…
Device-Independent Quantum Key Distribution: Protocols, Quantum Games, and Security
Syed M. Arslan, Saif Al-Kuwari, M. T. Rahim +1
Quantum Key Distribution (QKD) is based on the laws of quantum mechanics to enable provably secure communication. Despite its theoretical security promise, practical QKD systems ar…
Controlled quantum secure remote sensing
Muhammad Talha Rahim, Saif Al-Kuwari, Mahmood Irtiza Hussain +1
Quantum resources enable secure quantum sensing (SQS) of remote systems, offering significant advantages in precision and security. However, decoherence in the quantum communicatio…
