 Marilyn Hawley of the Materials Science and Technology Division is exploring a novel "bottom-up" fabrication approach
to using a scanning tunneling microscope to create a solid-state, silicon-based, quantum computer. The approach involves the fabrication of
atoms in a spin array, which could be the functional basis of a quantum computer.
 Toni Taylor is a physicist working in the Laboratory's Materials Science and Technology Division. Taylor is interested in the ways in which ultrafast optical pulses of light might be used to selectively excite such complex
materials systems as nonlinear optical crystals, semiconductor quantum dots, and bulk materials, in order to prepare and manipulate specific electronic and photonic quantum states which may be of critical
importance for building future quantum electronic and photonic devices.
Coherent control of quantum mechanical states can provide qualitatively new
modes of computation and communication. The methods to experimentally manipulate
quantum states are well established for isolated atoms and molecules.
Coherent Quantum Control
The field of coherent quantum control in condensed-matter systems
remains relatively untouched, yet the ability to coherently manipulate solids
is of critical importance for building future quantum information devices.
We are developing methods to coherently prepare and manipulate and interrogate
quantum states in condensed matter systems using several
complementary classes of excitations such as electron spins in solids, excitons
in semiconductor
quantum dots, vibrational states in molecular crystals, and surface plasmons
in metal nanostructures.
