... quantum dots rather than by spectroscopic manipulation as in other models. The tunnel barrier between dots can be high or low by setting a gate voltage. In the case of the high barrier potential the tunnelling is forbidden between dots (no evolution in time). In the low barrier potential spins will ...

Theory of quantum state control with solid-state qubits Research supervisor
... The potential to exploit quantum-mechanics in technology, from sensors to computers, is vast. Essential for these developments, however, is the ability to take a quantum system with a few discrete states, such as an exciton in a quantum dot or impurity state in a crystal, and control its wavefunctio ...

... In this class I would like for you to develop a “quantum worldview” – by which I mean that I would like to re-examine some of the concepts that you have previously, in classes like classical mechanics and electricity and magnetism, held as starting assumptions. In doing this, you will need to learn ...
