Spin-glasses in optical cavity
Chiu Fan Lee, Neil F. Johnson
Recent advances in nanofabrication and optical control have garnered tremendous interest in multi-qubit-cavity systems. Here we analyze a spin-glass version of such a nanostructure…
A robust one-step catalytic machine for high fidelity anti-cloning and W-state generation in a multi-qubit system
Alexandra Olaya-Castro, Neil F. Johnson, Luis Quiroga
We propose a physically realizable machine which can either generate multiparticle W-like states, or implement high fidelity () anti-cloning of an arbit…
Quantum Information Processing in Nanostructures
Alexandra Olaya-Castro, Neil F. Johnson
Semiconductor quantum dots integrated with ultrafast spectroscopy technology are prime candidates for building scalable architectures for Quantum Information Processing. In this re…
Efficient quantum computation within a disordered Heisenberg spin-chain
Chiu Fan Lee, Neil F. Johnson
We show that efficient quantum computation is possible using a disordered Heisenberg spin-chain with `always-on' couplings. Such disorder occurs naturally in nanofabricated systems…
First-order super-radiant phase transitions in a multi-qubit--cavity system
Chiu Fan Lee, Neil F. Johnson
We predict the existence of novel first-order phase transitions in a general class of multi-qubit-cavity systems. Apart from atomic systems, the associated super-radiant phase tran…
