Quantum Fisher Information as the Speed Limit for Multipartite Entanglement
Zain H. Saleem, Da-Wei Luo, Anjala M. Babu +3
We derive a universal upper bound on the speed of multipartite entanglement generation. For arbitrary differentiable pure multipartite states undergoing parameter-dependent evoluti…
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…
Quantum Advantage in Distributed Sensing with Noisy Quantum Networks
Allen Zang, Alexander Kolar, Alvin Gonzales +5
We show that quantum advantage in distributed sensing can be achieved with noisy quantum networks which only distribute noisy entangled states. We derive a closed-form expression o…
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…
Achieving the Heisenberg limit with Dicke states in noisy quantum metrology
Zain H. Saleem, Michael Perlin, Anil Shaji +1
Going beyond the standard quantum limit in noisy quantum metrology is an important and challenging task. Here we show how Dicke states can be used to surpass the standard quantum l…
