Quantum Fisher Information and the Curvature of Entanglement
Zain H. Saleem, Anil Shaji, Anjala M Babu +4
We explore the relationship between quantum Fisher information (QFI) and the negative of the second derivative of concurrence with respect to the coupling between two qubits, refer…

Two-qubit charger-battery system subject to weak, continuous measurements with quantum point contacts
Banumathy Manickam, Anil Shaji
Quantum batteries modeled as two-qubit systems coupled to Markovian thermal reservoirs have been shown to benefit from measurement-assisted charging, where projective measurements…

Enhanced quantum sensing mediated by a cavity in open systems
Quinn Langfitt, Zain H. Saleem, Tian Zhong +2
We simulate the dynamics of systems with = 1-20 qubits coupled to a cavity in order to assess their potential for quantum metrology of a parameter in the open systems limit. Th…
