Bayesian quantum noise spectroscopy

New Journal of Physics, 2018
As commonly understood, the noise spectroscopy problem—characterizing the statistical properties of a noise process affecting a quantum system by measuring its response—is mathematically ill-posed, in the sense that no unique noise process leads to a set

Experimental graybox quantum system identification and control

npj Quantum Information
Understanding and controlling engineered quantum systems is key to developing practical quantum technology. However, given the current technological limitations, such as fabrication imperfections and environmental noise, this is not always possible.

Unification of Relativistic and Quantum Mechanics from Elementary Cycles Theory

, 2016
In Elementary Cycles theory elementary quantum particles are consistently described as the manifestation of ultra-fast relativistic spacetime cyclic dynamics, classical in the essence.

Quantum regression theorem and non-Markovianity of quantum dynamics

, 2014
We explore the connection between two recently introduced notions of non-Markovian quantum dynamics and the validity of the so-called quantum regression theorem.

Quantum key distribution without sending a quantum signal

New Journal of Physics, 2015
Quantum Key Distribution is a quantum communication technique in which random numbers are encoded on quantum systems, usually photons, and sent from one party, Alice, to another, Bob. Using the data sent via the quantum signals, supplemented by classical
