Identifying a Two-State Hamiltonian in the Presence of Decoherence
Jared H. Cole, Andrew D. Greentree, Daniel K. L. Oi +3
Mapping the system evolution of a two-state system allows the determination of the effective system Hamiltonian directly. We show how this can be achieved even if the system is dec…
Identifying an Experimental Two-State Hamiltonian to Arbitrary Accuracy
Jared H. Cole, Sonia G. Schirmer, Andrew D. Greentree +3
Precision control of a quantum system requires accurate determination of the effective system Hamiltonian. We develop a method for estimating the Hamiltonian parameters for some un…
Dissipative Quantum Control
Allan I Solomon, Sonia G Schirmer
Nature, in the form of dissipation, inevitably intervenes in our efforts to control a quantum system. In this talk we show that although we cannot, in general, compensate for dissi…
Implementation of controlled multi-qudit operations for a solid-state quantum computer based on charge qudits
S. G. Schirmer, A. D. Greentree, D. K. L. Oi
We consider a mechanism to generate controllable qudit-qudit interactions in a charge-position paradigm for a quantum computer, through the use of auxiliary states. By controlling…
Controllability of Quantum Systems
S. G. Schirmer, I. C. H. Pullen, A. I. Solomon
An overview and synthesis of results and criteria for open-loop controllability of Hamiltonian quantum systems obtained using Lie group and Lie algebra techniques is presented. Neg…
Dissipative "Groups" and the Bloch Ball
Allan I. Solomon, Sonia G. Schirmer
We show that a quantum control procedure on a two-level system including dissipation gives rise to a semi-group corresponding to the Lie algebra semi-direct sum gl(3,R)+R^3. The ph…
