Three-spin interactions and entanglement in optical lattices
Jiannis K. Pachos
The entanglement properties of some novel quantum systems are studied that are inspired by recent developments in cold-atom technology. A triangular optical lattice of two atomic s…
Geometric phases and criticality in spin chain systems
Angelo C. M. Carollo, Jiannis K. Pachos
A relation between geometric phases and criticality of spin chains is established. As a result, we show how geometric phases can be exploited as a tool to detect regions of critica…
Conditional Aharonov-Bohm Phases with Double Quantum Dots
Roberta Rodriquez, Jiannis K. Pachos
A quantum dot proposal for the implementation of topological quantum computation is presented. The coupling of the electron charge to an external magnetic field via the Aharonov-Bo…
Quantum gates and decoherence
Stefan Scheel, Jiannis Pachos, E. A. Hinds +1
In the lectures we will be concerned with some aspects of physical implementations of quantum gate operations which are necessary for quantum information processing. We will discus…
Generation and degree of entanglement in a relativistic formulation
Jiannis Pachos, Enrique Solano
The generation of entangled states and their degree of entanglement is studied ab initio in a relativistic formulation for the case of two interacting spin-1/2 charged particles. I…
Optical Holonomic Quantum Computation
Demosthenes Ellinas, Jiannis Pachos
Holonomic quantum computation (HQC) is materialized here with quantum optics components. Holonomies are the generalization of the Berry phases to unitary matrices with dimensionali…
