Taming the Rotating Wave Approximation
Daniel Burgarth, Paolo Facchi, Robin Hillier +1
The interaction between light and matter is one of the oldest research areas of quantum mechanics, and a field that just keeps on delivering new insights and applications. With the…
Non-Markovian noise that cannot be dynamically decoupled by periodic spin echo pulses
Daniel Burgarth, Paolo Facchi, Martin Fraas +1
Dynamical decoupling is the leading technique to remove unwanted interactions in a vast range of quantum systems through fast rotations. But what determines the time-scale of such…
Dynamical Decoupling of Unbounded Hamiltonians
Christian Arenz, Daniel Burgarth, Paolo Facchi +1
We investigate the possibility to suppress interactions between a finite dimensional system and an infinite dimensional environment through a fast sequence of unitary kicks on the…
Dynamical Decoupling and Homogenization of continuous variable systems
Christian Arenz, Robin Hillier, Daniel Burgarth
For finite-dimensional quantum systems, such as qubits, a well established strategy to protect such systems from decoherence is dynamical decoupling. However many promising quantum…
A continuous-time diffusion limit theorem for dynamical decoupling and intrinsic decoherence
Robin Hillier, Christian Arenz, Daniel Burgarth
We discuss a few mathematical aspects of random dynamical decoupling, a key tool procedure in quantum information theory. In particular, we place it in the context of discrete stoc…
Distinguishing decoherence from alternative quantum theories by dynamical decoupling
Christian Arenz, Robin Hillier, Martin Fraas +1
A longstanding challenge in the foundations of quantum mechanics is the verification of alternative collapse theories despite their mathematical similarity to decoherence. To this…
