This page lists Oxford groups whose quantum research focuses on molecular systems (including synthesis and characterisation of molecular structures, and incorporation of such structures into nanoelectronics) and solid state systems including a range of spin based and optoelectronic quantum devices.

Studying the dynamics of photoexcited electrons and holes using measurements on the timescale of about 100 femtoseconds by ultrafast optical spectroscopy.   The dynamics are interesting both from a fundamental point of view, and because they limit the speed ultimately obtainable in electronic and opto-electronic devices.

Leader: Robert Taylor

Postdocs: 
Ben Reid
David Coles

Students:
Christopher Chan and Hee Dae Kim.

Stephanie Simmons' Group:
Nuclear and Electron Spin Devices
(Materials Department)

Image: Artist's impression of control field to manipulate spin qubit.

Engineering devices to store and manipulate information in the form of 'spin', a property of individual electrons and the nuclei of certain atoms. The spin is a superb choice for storing quantum bits (qubits) because it interacts relatively weakly with other degrees of freedom such as electric charge, and therefore it can persist for long periods - up to hours in the case of nuclear spins.

Designing and synthesising new molecular materials, and explores how their properties relate to their molecular structures. This is "molecular engineering" – engineering at the nanoscale. The group creates structures that are vital to studies of quantum phenomena in Physics and Materials. 

Leader: Harry Anderson

Postdocs: Total of five, of whom one or two will typically be synthesising structures for quantum studies.

Students:  
Total of six, of whom two will typically be synthesising molecular structures such as, e.g., biomimetic porphyrin rings for studies of quantum coherence of optically excited states (see Herz group).

Image:  Layer of porphyrin nanorings may mimic photosynthesis.

Light-harversting in natural photosynthetic organisms can be remarkably fast and efficient, because the excited states can be delocalized over several molecular units as one quantum-mechanical state. We explore how such delocalised excited states may be used in synthetic, man-made molecules that may be incorporated in a new generation of efficient photovoltaic materials.

Leader: Laura Herz

Postdoc: Patrick Parkinson

Students: Beate Dirks, Chris Menelaou, Christian Wehrenfennig, Christian Weisspfennig.
