IJQI to review special issue articles on Quantalk

An upcoming Special Issue of the International Journal of Quantum Information (IJQI) will focus on the topic of distributed quantum computing. This a paradigm may offer a solution to the problem of scaling up quantum computers. Some of the papers for this issue will be reviewed right here on quantalk.org, in open threads readable by everyone.

Graphene, time for nanotubes to roll over?

by Christoph Stampfer

The recent experimental discovery of graphene [1, 2], filling the gap between quasi 1-dimensional (1-D) nanotubes and 3-D graphite makes truly 2-D solid state systems accessible. Both graphene and carbon nanotubes exhibit unique electronic properties which make these materials promising candidates for future high mobility nanoelectronics and potential extensions to downscaling state-of-the-art silicon technology [3]. In this context, graphene and carbon nanotubes are both interesting materials for future information technology, including solid state quantum computation [4], whose backbone is the initialization, manipulation, and detection of states in two-level quantum systems, the so-called qubits. In semiconductor quantum dots, the electron spin (state up or dow...
