Ultrafast optical signature of quantum superpositions in a nanostructure

F. J. Rodriguez, L. Quiroga, N. F. Johnson

We propose an unambiguous signature for detecting quantum superposition states in a nanostructure, based on current ultrafast spectroscopy techniques. The reliable generation of su…

Predictability of large future changes in a competitive evolving population

D. Lamper, S. Howison, N. F. Johnson

The dynamical evolution of many economic, sociological, biological and physical systems tends to be dominated by a relatively small number of unexpected, large changes (`extreme ev…

Decoherence of quantum registers

John H. Reina, Luis Quiroga, Neil F. Johnson

The dynamical evolution of a quantum register of arbitrary length coupled to an environment of arbitrary coherence length is predicted within a relevant model of decoherence. The r…

Quantum information processing in semiconductor nanostructures

John H. Reina, Luis Quiroga, Neil F. Johnson

A major question for condensed matter physics is whether a solid-state quantum computer can ever be built. Here we discuss two different schemes for quantum information processing…

An NMR-based nanostructure switch for quantum logic

John H. Reina, Luis Quiroga, Neil F. Johnson

We propose a nanostructure switch based on nuclear magnetic resonance (NMR) which offers reliable quantum gate operation, an essential ingredient for building a quantum computer. T…

Quantum entanglement and information processing via excitons in optically-driven quantum dots

John H. Reina, Luis Quiroga, Neil F. Johnson

We show how optically-driven coupled quantum dots can be used to prepare maximally entangled Bell and Greenberger-Horne-Zeilinger states. Manipulation of the strength and duration…
