Phase-asymmetry resource interconversion via estimation
Varun Narasimhachar, Gilad Gour
Practical implementations of quantum information-theoretic applications rely on phase coherences between systems. These coherences are disturbed by misalignment between phase refer…
Squashing model for detectors and applications to quantum key distribution protocols
Oleg Gittsovich, Normand J. Beaudry, Varun Narasimhachar +3
We develop a framework that allows a description of measurements in Hilbert spaces that are smaller than their natural representation. This description, which we call a "squashing…
The resource theory of informational nonequilibrium in thermodynamics
Gilad Gour, Markus P. Müller, Varun Narasimhachar +2
We review recent work on the foundations of thermodynamics in the light of quantum information theory. We adopt a resource-theoretic perspective, wherein thermodynamics is formulat…
