Photon Demultiplexing Using Spatial Routing
Hashir Kuniyil, Asad Ali, Saif Al-Kuwari
Spatial sectioning of the far-field noncollinear field from spontaneous parametric down-conversion (SPDC) is a promising approach for multiparty quantum communication. Although dem…
Spectral filtering and crystal length as control parameters for conditional correlations in quantum imaging
Hashir Kuniyil, Asad Ali, Mohammadreza Rezaee +1
We establish spectral filtering as a control parameter for the conditional momentum and position correlations of SPDC biphotons used in quantum imaging. The conditional momentum un…
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…
Bright-state source cancellation in dissipative shortcut Raman atom optics
Asad Ali, Saif Al-Kuwari, M. I. Hussain +3
Spontaneous Raman scattering limits shortcut-assisted atom optics, but its microscopic origin is obscured once the lossy excited state is adiabatically eliminated. We organize the…
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…
