Exploring super-radiant phase transitions via coherent control of a multi-qubit--cavity system
Timothy C. Jarrett, Chiu Fan Lee, Neil F. Johnson
We propose the use of coherent control of a multi-qubit--cavity QED system in order to explore novel phase transition phenomena in a general class of multi-qubit--cavity systems. I…

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…
