Demonstration of a simple entangling optical gate and its use in Bell-state analysis [PDF]

, 2005
We demonstrate a new architecture for an optical entangling gate that is significantly simpler than previous realisations, using partially-polarising beamsplitters so that only a single optical mode-matching condition is required.

The ubiquity of conservative translations

, 2012
We study the notion of conservative translation between logics introduced by Feitosa and D'Ottaviano. We show that classical propositional logic (CPC) is universal in the sense that every finitary consequence relation over a countable set of formulas can

Quantum state manipulation of trapped atomic ions [PDF]

, 1996
A single laser-cooled and trapped 9Be+ ion is used to investigate methods of coherent quantum-state synthesis and quantum logic. We create and characterize nonclassical states of motion including "Schroedinger-cat" states.

Reflections on Zeilinger-Brukner information interpretation of quantum mechanics

, 2016
In this short review I present my personal reflections on Zeilinger-Brukner information interpretation of quantum mechanics (QM). In general, this interpretation is very attractive for me.

Engineering superpositions of displaced number states of a trapped ion

, 2004
We present a protocol that permits the generation of a subtle with superposition with 2^(l+1) displaced number states on a circle in phase space as target state for the center-of-mass motion of a trapped ion.

Betting on Quantum Objects [PDF]

, 2017
Dutch book arguments have been applied to beliefs about the outcomes of measurements of quantum systems, but not to beliefs about quantum objects prior to measurement. In this paper, we prove a quantum version of the probabilists' Dutch book theorem that

Quantifiers for a Modal Future

Philosophical Perspectives, EarlyView.
ABSTRACT Future auxiliaries present a challenge to the classical analysis of modal expressions as existential or universal quantifiers over a contextually provided set of possible worlds: these expressions come with a distinct modal flavor, but their interaction with negation and the fact that future judgments come in degrees of confidence is ...

Neurons and symbols: a manifesto [PDF]

, 2010
We discuss the purpose of neural-symbolic integration including its principles, mechanisms and applications. We outline a cognitive computational model for neural-symbolic integration, position the model in the broader context of multi-agent systems ...

Quantum Correlations and Global Coherence in Distributed Quantum Computing

, 2018
Deviations from classical physics when distant quantum systems become correlated are interesting both fundamentally and operationally. There exist situations where the correlations enable collaborative tasks that are impossible within the classical ...

Wigner Function Evolution of Quantum States in Presence of Self-Kerr Interaction [PDF]

, 2008
A Fokker-Planck equation for the Wigner function evolution in a noisy Kerr medium ($\chi^{(3)}$ non-linearity) is presented. We numerically solved this equation taking a coherent state as an initial condition. The dissipation effects are discussed.
