Multipartite entanglement measures via Bell basis measurements
Jacob L. Beckey, G. Pelegrí, Steph Foulds +1
We show how to estimate a broad class of multipartite entanglement measures from Bell basis measurement data. In addition to lowering the experimental requirements relative to prev…
Opportunities and Limitations in Broadband Sensing
Anthony M. Polloreno, Jacob L. Beckey, Joshua Levin +5
We consider estimating the magnitude of a monochromatic AC signal that couples to a two-level sensor. For any detection protocol, the precision achieved depends on the signal's fre…
Computable and operationally meaningful multipartite entanglement measures
Jacob L. Beckey, N. Gigena, Patrick J. Coles +1
Multipartite entanglement is an essential resource for quantum communication, quantum computing, quantum sensing, and quantum networks. The utility of a quantum state, ,…
Sub-Quantum Fisher Information
M. Cerezo, Akira Sone, Jacob L. Beckey +1
The Quantum Fisher Information (QFI) plays a crucial role in quantum information theory and in many practical applications such as quantum metrology. However, computing the QFI is…
Variational Quantum Algorithm for Estimating the Quantum Fisher Information
Jacob L. Beckey, M. Cerezo, Akira Sone +1
The Quantum Fisher information (QFI) quantifies the ultimate precision of estimating a parameter from a quantum state, and can be regarded as a reliability measure of a quantum sys…
Generalized Measure of Quantum Fisher Information
Akira Sone, M. Cerezo, Jacob L. Beckey +1
In this work, we present a lower bound on the quantum Fisher information (QFI) which is efficiently computable on near-term quantum devices. This bound itself is of interest, as we…
