A Primer on Quantum Computing
18 Oct 2006   Contributor(s):: David D. Nolte
Quantum computers would represent an exponential increase in computing power...if they can be built. This tutorial describes the theoretical background to quantum computing, its potential for several specific applications, and the demanding challenges facing practical implementation. The field...

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...

Atomistic Modeling of Nano Devices: From Qubits to Transistors
13 Apr 2016   Contributor(s):: Rajib Rahman
In this talk, I will describe such a framework that can capture complex interactions ranging from exchange and spinorbitvalley coupling in spin qubits to nonequilibrium charge transport in tunneling transistors. I will show how atomistic full configuration interaction calculations of exchange...

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...

This presentation deals with the Einstein/Bohr Debate and Quantum Computing.

Equipment, Techniques, and Growth of UltraHigh Purity AlGaAsGaAs Heterostructures by Molecular Beam Epitaxy
25 May 2017   Contributor(s):: Geoff Gardner
In this talk I detail research and investigation into critical equipment and materials engineering issues related to the quality of the fabricated 2DEG systems. I also will present data that demonstrates the critical role gallium purity plays in 2DEG mobility.

MCW07 A Quantum Open Systems Approach to MolecularScale Devices
25 Feb 2008   Contributor(s):: Yongqiang Xue
Experimental advances in electrically and optically probing individual molecules have provided new insights into the behavior of single quantum objects and their interaction with the nanoenvironments without requiring ensemble average. Molecularscale devices are open quantum systems whose...

MCW07 Physics of Contact Induced Current Asymmetry in Transport Through Molecules
25 Feb 2008   Contributor(s):: Bhaskaran Muralidharan, owen miller, Neeti Kapur, Avik Ghosh, Supriyo Datta
We first outline the qualitatively different physics involved in the charginginduced current asymmetries in molecular conductors operating in the strongly coupled (weakly interacting) selfconsistent field (SCF) and the weakly coupled (strongly interacting) Coulomb Blockade (CB) regimes. The CB...

Oxide Systems – An Answer to the Qubit Problem?
07 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...
