Finite key effects in satellite quantum key distribution
Jasminder S. Sidhu, Thomas Brougham, Duncan McArthur +2
Global quantum communications will enable long-distance secure data transfer, networked distributed quantum information processing, and other entanglement-enabled technologies. Sat…
Quantum receiver for phase-shift keying at the single photon level
Jasminder S. Sidhu, Shuro Izumi, Jonas S. Neergaard-Nielsen +2
Quantum enhanced receivers are endowed with resources to achieve higher sensitivities than conventional technologies. For application in optical communications, they provide improv…
Tight bounds on the simultaneous estimation of incompatible parameters
Jasminder S. Sidhu, Yingkai Ouyang, Earl T. Campbell +1
The estimation of multiple parameters in quantum metrology is important for a vast array of applications in quantum information processing. However, the unattainability of fundamen…
A Geometric Perspective on Quantum Parameter Estimation
Jasminder S. Sidhu, Pieter Kok
Quantum metrology holds the promise of an early practical application of quantum technologies, in which measurements of physical quantities can be made with much greater precision…
Quantum Fisher information for general spatial deformations of quantum emitters
Jasminder S. Sidhu, Pieter Kok
We present a framework for the detection and estimation of deformations applied to a grid of sources. Our formalism uses the Hamiltonian formulation of the quantum Fisher informati…
