Field-Based Formalism for Calculating Multi-Qubit Exchange Coupling Rates for Transmon Qubits
Ghazi Khan, Thomas E. Roth
Superconducting qubits are one of the most mature platforms for quantum computing, but significant performance improvements are still needed. To improve the engineering of these sy…

Detection of weak magnetic fields using nitrogen-vacancy centers with maximum confidence
Ghazi Khan, Adam Zaman Chaudhry
The problem of detection of magnetic fields using NV centers, that is, to check whether a weak magnetic field is present or not, can be tackled using quantum state discrimination t…

The quantum Zeno and anti-Zeno effects in the strong coupling regime
Ghazi Khan, Hudaiba Soomro, Muhammad Usman Baig +2
It is well known that repeated projective measurements can either speed up (the Zeno effect) or slow down (the anti-Zeno effect) quantum evolution. Until now, however, studies of t…
