Oxide Systems – An Answer to the Qubit Problem?
08 Mar 2016   Contributor(s):: Sudhakar Yarlagadda
One can produce new oxidebased devices by exploiting their tunability, rich physics, and coupling between the various degrees of freedom (such as charge, lattice, spin, etc.). We propose that oxidebased double quantum dots with only one electron (tunneling between the dots) can be regarded as...

The Pioneers of Quantum Computing
19 Nov 2010   Contributor(s):: David P. Di Vincenzo
This talk profiles the persons whose insights and visions created the subject of quantum information science. Some famous, some not, they all thought deeply about the puzzles and contradictions that were apparent to the founders of quantum theory. After many years of germination, the confluence...

An Introduction to Quantum Computing
12 Sep 2008   Contributor(s):: Edward Gerjuoy
Quantum mechanics, as formulated more than 80 years ago by Schrodinger, Heisenberg, Dirac and other greats, is a wholly sufficient foundation for its modern interrelated subfields of quantum computation (qc) and quantum information (qi), which generally are lumped together into a single subfield...

Control of Exchange Interaction in a Double Dot System
05 Feb 2004   Contributor(s):: Mike Stopa
As Rolf Landauer observed in 1960, information is physical. As a consequence, the transport and processing of information must obey the laws of physics. It therefore makes sense to base the laws of information processing and computation on the laws of physics and in particular on quantum...
