Workshop overview

Quantum computation uses quantum mechanical phenomena to perform operations on data measured by qubits. It is part of quantuminformation processing, which has the potential to revolutionize our methods of securing, processing, storing, retrieving, transmitting anddisplaying information. A quantum computer can implement new algorithms, to perform e.g. rapid integer factorization, therebythreatening current cryptosystems, and quicker database searches. Practical difficulties have limited us to seven qubitcomputers so far, but the possibilities of this emerging technology have led to many centers, learned and popular articles, and even themovie "Timeline". In this workshop, three experts in the theoretical, experimental, and engineering aspects of quantum computation will takeus from basics to cutting-edge.

Remark: This workshop was held on February 10, 2005 as part of the Computational Sciences Lecture Series (CSLS) at the University of Wisconsin-Madison.

Quantum information, computation, and communication

By Prof. Richard Cleve (University of Waterloo, Canada)

(Slides are not available) | Video [WMV]

ABSTRACT: A quantum computer is an information processing device that harnesses the strange power of quantum mechanics: it can exist inseveral states simultaneously and its computation paths can interfere with each other. Following a brief introduction to quantuminformation, the talk will review developments in quantum algorithms and various notions of communication with quantum information.

Prospects for real quantum information processing devices in the laboratory

By Dr. David DiVincenzo(IBM Watson Research Center, USA)

Slides of talk [PDF] | Video [WMV]

ABSTRACT: Some very hard things have to happen in the laboratory tomake even rudimentary quantum information processing a reality. I will give a report "from the trenches" to give some idea of how you startfrom scratch -- in a state of the art solid state physics lab -- and try to make a working qubit. I will also give a point of view onprogress on other fronts where things seem to be going better, in particular in the atomic physics lab.

The future of quantum information processing: how big, how fast, how powerful?

By Prof. Seth Lloyd (MIT, Cambridge, Massachusetts, USA)

(Slides are not available) | Video [WMV]

ABSTRACT: Existing quantum computers and quantum communication systems operate at the fundamental performance limits posed by the laws ofphysics. This talk reviews the physical limits to quantum information processing, and explores the future of the field.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
