Detector-Frame Quantum Limits for Heterodyne Timing in Relativistic Optical Links
Salman Sajad Wani, Aatif Kaisar Khan, Saif Al-Kuwari +1
Long-baseline optical links for space interferometry and satellite quantum networks rely on heterodyne phase tracking under Doppler motion and gravitational frequency shifts. These…
Constructive realization of self-referential prediction limits in quantum control: Resource bounds and Gödel-safe architectures
Salman Sajad Wani, Álvaro Perales-Eceiza, Saif Al-Kuwari +1
Programmable quantum control systems increasingly rely on predictive modules for certification, real-time feedback, and autonomous decision-making. This development raises a fundam…
Quantum Speed Limit under Calibration Uncertainty
Salman Sajad Wani, Saif Al-Kuwari
Standard quantum speed limits presuppose exactly known parameters, overestimating operational speed under calibration uncertainty. We introduce a projected speed limit based on the…
Mechanical Squeezed-Fock Gravimeter
Rozhin Yousefjani, Saif Al-Kuwari
Levitated mechanical systems are promising candidates for quantum gravimetry, as gravity couples directly to their center-of-mass motion, enabling the large mass of a mesoscopic pa…
Asynchronous Routing for Multipartite Entanglement in Quantum Networks
Chenliang Tian, Zebo Yang, Raj Jain +6
In quantum networks, one way to communicate is to distribute entanglements through swapping at intermediate nodes. Most existing work primarily aims to create efficient two-party e…
Time uncertainty and fundamental sensitivity limits in quantum sensing: application to optomechanical gravimetry
Salman Sajad Wani, Saif Al-Kuwari, Arshid Shabir +3
High-sensitivity accelerometers and gravimeters, achieving the ultimate limits of measurement sensitivity are key tools for advancing both fundamental and applied physics. While nu…
