A proposal for the implementation of quantum gates with photonic-crystal coupled cavity waveguides
Dimitris G. Angelakis, Marcelo Franca Santos, Vassilis Yannopapas +1
Quantum computers require technologies that offer both sufficient control over coherent quantum phenomena and minimal spurious interactions with the environment. We show, that phot…
Photonic crystals and inhibition of spontaneous emission: an introduction
Dimitris G. Angelakis, Peter L. Knight, Emmanuel Paspalakis
In the first part of this introductory review we outline the developments in photonic band gap materials from the physics of photonic band gap formation to the fabrication and pote…
Entanglement in a Two-Qubit Ising Model Under a Site-Dependent External Magnetic Field
Andreas F. Terzis, Emmanuel Paspalakis
We investigate the ground state and the thermal entanglement in the two-qubit Ising model interacting with a site-dependent magnetic field. The degree of entanglement is measured b…
On the relation between quantum mechanical probabilities and event frequencies
Charis Anastopoulos
The probability `measure' for measurements at two consecutive moments of time is non-additive. These probabilities, on the other hand, may be determined by the limit of relative fr…
