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…
Non-Cooperative Quantum Game Theory
Chiu Fan Lee, Neil F. Johnson
The physical world obeys the rules of quantum, as opposed to classical, physics. Since the playing of any particular game requires physical resources, the question arises as to how…
Quantum coherence, correlated noise and Parrondo games
Chiu Fan Lee, Neil F. Johnson, Ferney Rodriguez +1
We discuss the effect of correlated noise on the robustness of quantum coherent phenomena. First we consider a simple, toy model to illustrate the effect of such correlations on th…
Exploiting Randomness in Quantum Information Processing
Chiu Fan Lee, Neil F. Johnson
We consider how randomness can be made to play a useful role in quantum information processing - in particular, for decoherence control and the implementation of quantum algorithms…
