We give a new algorithm for computing the robustness of magic - a measure of the utility of quantum states as a computational resource. Our work is motivated by the magic state model of fault-tolerant quantum computation. In this model, all unitaries…

Orbital angular momentum (OAM) of light holds great promise for quantum key distribution protocols either by increasing the number of channels or by allowing for high-dimensional encoding schemes. However, OAM modes are strongly distorted by…

The quantum capacity of a quantum channel captures its capability for noiseless quantum communication. It lies at the heart of quantum information theory.

How does classical chaos affect the generation of quantum entanglement? What signatures of chaos exist at the quantum level and how can they be quantified?

A quantum channel with correlations among only certain subsystems can be viewed as a "correlation with subsystem constraints".

In the quest for quantum gravity Hardy suggests the radical aspects of quantum physics (probabilistic nature) and relativity (dynamic causality) would manifest together.

Epistemic models of nature prove to be problematic in many settings, particularly in those for which measurement procedures are ill-defined.

We consider relativistic, oscillating centre of mass photon detector modeled as harmonic oscillator that are coupled to a cavity mode.
