Full scientific program:  Symposium N 395.26 Kb

This E-MRS symposium will bring together experts both from the materials research and the quantum information communities to cross-fertilize both fields. The goal of this symposium is to communicate the needs of the upcoming quantum information technologies on the materials research side and, conversely, to communicate the capabilities of cutting-edge research in materials science to the quantum information community. We expect that this will be an important opportunity for both fields.

Scope and topics
Quantum information exploits new modes of computation and communication based on the physical laws of quantum mechanics instead of classical physics. Among these are the use of quantum states for secure transmission of information (quantum cryptography), the use of quantum entanglement to permit reliable transmission of quantum states (teleportation), the possibility of preserving quantum coherence in the presence of irreversible noise processes (quantum error correction), and the use of controlled quantum evolution for highly efficient computation (quantum computation). On the side of materials research, the main challenges are in the area of nanostructuring, purification, and characterization at the nanometer scale. The following material systems have been identified as promising candidates for future applications in quantum information technologies: i) semiconductor quantum dots (III-V semiconductor heterostructures), ii) impurity spins in solids: dopant atoms in semiconductors (phosphorus or deep donors in silicon), color centers in diamond, paramagnetic ions in C60 or in carbon nanotubes, rare earth ions in dielectric solids, iii) superconducting junctions.

The symposium will address the following topics applied to quantum information. Contributions are invited on, but not limited to:
- Semiconductor quantum dots
- Impurity spins in solids
- Superconducting circuits

A special session will be devoted to color centers in diamond. A common session between Symposium N and Symposium R (Design, characterisation and modelling of molecule-based magnetic materials) will be organized in order to discuss topics of common interest in the fields of molecular magnetism and impurity spins in solids such as: definition and manipulation of electron spin states, suitable schemes and architectures, entanglement, decoherence mechanisms, and read out methods for single impurity or molecular spin.
