Project Revision
Workpackage 6 Revised
To stick realistically to the revision of the main project goal, WP6 was renamed from “Qubit measurement” to “Exploration of the fundamentals of quantum nanomagnets”.
WP6: Exploration of the fundamentals of quantum nanomagnets
Starting date: 01 January 2003 (Month 12).
Ending date: 31 December 2004 (Month 36).
Participants: UB, NPL, CSIC.
Objectives
- To use the state-of-the-art devices developed in WP5 to measure the fundamental physical properties of quantum nano-magnets.
- Ideally the devices developed will be able to interrogate a single molecular nano-magnet.
- Novel interrogation systems will be developed that will enable near quantum-limited detection sensitivity.
Work details
- Using the devices developed in WP5 we will make measurements on low number density of magnetic nano-magnets with the aim of being able to make measurements on single nano-magnets.
- The measurements will include the behaviour of the nano-magnets in the regime where they show quantum behaviour, with the aim to fully characterise their quantum properties thus enabling a realistic and experimentally determined statement as to the effective future potential use of such nano-magnets in QIP.
- Noise sources, back-action and decoherence measurements will form a critical aspect of this work.
- Schemes to effectively couple nano-magnets to the devices will be explored, such as scanned probe manipulation of nano-magnets, flip-chip design andnano-lithography.
Deliverables
- D6.1 (month 24): Report on the study of measurement system.
- D6.2 (month 36): Report on measurements of fundamental properties of nano-magnets and their future applicability to QIP.
Milestones and expected results
- M6.1 (month 36): To implement time resolved switching measurements of amicro-SQUID/device and the role of back-action, and the modelling of such processes. Publication of measurements on single/low numbers of molecular nano-magnets.
- M6.2 (month 36): To couple a SQUID/device to a nanomagnet and tomeasure fundamental properties of nano-magnets coupled to the device.
