Interpretive Themes in Quantum Physics: Curriculum Development and Outcomes [PDF]

open access: yes, 2011
A common learning goal for modern physics instructors is for students to recognize a difference between the experimental uncertainty of classical physics and the fundamental uncertainty of quantum mechanics.

Quantum jumps are more quantum than quantum diffusion

open access: yesNew Journal of Physics, 2014
It was recently argued (Wiseman and Gambetta 2012 Phys. Rev. Lett. http://dx.doi.org/10.1103/PhysRevLett.108.220402 108 http://dx.doi.org/10.1103/PhysRevLett.108.220402 ) that the stochastic dynamics (jumps or diffusion) of an open quantum system are not

Autonomous quantum to classical transitions and the generalized imaging theorem

open access: yesNew Journal of Physics, 2016
The mechanism of the transition of a dynamical system from quantum to classical mechanics is of continuing interest. Practically it is of importance for the interpretation of multi-particle coincidence measurements performed at macroscopic distances from

Uncertainty relations for angular momentum

open access: yesNew Journal of Physics, 2015
In this work we study various notions of uncertainty for angular momentum in the spin- s representation of SU(2). We characterize the ‘uncertainty regions’ given by all vectors, whose components are specified by the variances of the three angular ...

Anti-Newtonian dynamics and self-induced Bloch oscillations of correlated particles

open access: yesNew Journal of Physics, 2014
We predict that two correlated particles hopping on a one-dimensional Hubbard lattice can show transient self-acceleration and self-induced Bloch oscillations as a result of anti-Newtonian dynamics.

Interaction-free evolution in the presence of time-dependent Hamiltonians [PDF]

open access: yes, 2015
The generalization of the concept of interaction-free evolutions (IFE) [A. Napoli, {\it et al.}, Phys. Rev. A {\bf 89}, 062104 (2014)] to the case of time-dependent Hamiltonians is discussed. It turns out that the time-dependent case allows for much more

Quantifying coherence [PDF]

open access: yes, 2014
We introduce a rigorous framework for the quantification of coherence and identify intuitive and easily computable measures of coherence. We achieve this by adopting the viewpoint of coherence as a physical resource.

Enhancing pseudo-telepathy in the Magic Square game [PDF]

open access: yes, 2013
We study the possibility of reversing an action of a quantum channel. Our principal objective is to find a specific channel that reverses as accurately as possible an action of a given quantum channel. To achieve this goal we use semidefinite programming.

Orthogonal vector computations

open access: yes, 2016
Quantum computation is the suitable orthogonal encoding of possibly holistic functional properties into state vectors, followed by a projective measurement.Comment: 8 pages, 2 figures, some revisions and ...

Thermal equilibration between two quantum systems

open access: yes, 2011
Two identical finite quantum systems prepared initially at different temperatures, isolated from the environment, and subsequently brought into contact are demonstrated to relax towards Gibbs-like quasi-equilibrium states with a common temperature and ...
