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…
Quantum information transport to multiple receivers
Andrew D. Greentree, Simon J. Devitt, Lloyd C. L. Hollenberg
The importance of transporting quantum information and entanglement with high fidelity cannot be overemphasized. We present a scheme based on adiabatic passage that allows for tran…
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…
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…
Quantum control using sequences of simple control pulses
S. G. Schirmer, A. D. Greentree, V. Ramakrishna +1
Structured decompositions of a desired unitary operator are employed to derive control schemes that achieve certain control objectives for finite-level quantum systems using only s…
Robust quantum memory via quantum control
Andrew D. Greentree, S. G. Schirmer, A. I. Solomon
A general scheme for building a quantum memory by transferring quantum information to an essentially decoherence-free memory transition using quantum control is presented and illus…
