Gravitational acceleration encoded in Jaynes Cummings exchange frequencies: Quantum Fisher information, readout, and validity conditions
Salman Sajad Wani, Mughees Ahmed Khan, Mohammad Haris Khan +3
We derive an effective trapped atom--cavity model in which a constant gravitational acceleration shifts the oscillator equilibrium and changes the local standing-wave coupling, the…

Chip-scale superconducting quantum gravimeter combining a SQUID, a transmon, and a nanomechanical resonator
Salman Sajad Wani, Mughees Ahmed Khan, Abrar Ahmed Naqash +1
Precise gravitational measurements are vital for geophysics and inertial navigation, but compact gravimeters with high measurement bandwidth remain difficult to realize. We propose…

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…
