First proposed in the 1970s, quantum computing relies on quantum physics by taking advantage of certain quantum physics properties of atoms or nuclei that allow them to work together as quantum bits, or qubits, to be the computer's processor and memory. By interacting with each other while being isolated from the external environment, qubits can perform certain calculations exponentially faster than conventional computers.

A Primer on Quantum Computing
out of 5 stars
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 spin-orbit-valley coupling in spin qubits to non-equilibrium 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...

Equipment, Techniques, and Growth of Ultra-High Purity AlGaAs-GaAs 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.
High Precision Quantum Control of Single Donor Spins in Silicon
14 Jan 2008 | | Contributor(s):: Rajib Rahman, marta prada, Gerhard Klimeck, Lloyd Hollenberg
The Stark shift of the hyperfine coupling constant is investigated for a P donor in Si far below the ionization regime in the presence of interfaces using tight-binding and band minima basis approaches and compared to the recent precision measurements. In contrast with previous effective...
MCW07 A Quantum Open Systems Approach to Molecular-Scale 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. Molecular-scale 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 charging-induced current asymmetries in molecular conductors operating in the strongly coupled (weakly interacting) self-consistent 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 oxide-based devices by exploiting their tunability, rich physics, and coupling between the various degrees of freedom (such as charge, lattice, spin, etc.). We propose that oxide-based double quantum dots with only one electron (tunneling between the dots) can be regarded as...
