Video: How to make a single photon emitter – Quantum optics of single atoms

Saturday, August 22nd, 2009

Comments

This video is not the most entertaining as the speaker has a thick Germanic accent.  However the topic of generating a single photon is important for being able to do experimental quantum physics. 

Summary

In recent years there has been increasing interest in systems capable to generate photon fields containing a preset number of photons. This has chiefly arisen from applications for which single photons are a necessary requirement, such as secure quantum communication and quantum cryptography. Photon number states or Fock states are also useful for generating multiple atom entanglements in strongly coupled systems such as the micromaser. The generated field and the pumping atoms are in an entangled state, this entanglement can be transferred by the field to subsequent atoms, leading to applications such as basic quantum logic gates. For our experiments we employ a micromaser having a cavity Q of 4 Ã 1010 corresponding to a photon lifetime of 0.3s which is the largest ever achieved in this type of experiments. A source of single photons or, more generally, arbitrary Fock states is also a useful tool for further investigations of atomfield interaction. It can be used to obtain the reconstruction of purely quantum states of the radiation field as represented by the Fock states. Recently we succeeded to combine an ion trap with an optical cavity. With this system also single photons in the visible spectral region can be produced on demand.«

Michael Palin – confessions of a trainspotter

Friday, April 17th, 2009

This video shot in 1980 is the beginning of what later because "Great Railway Journeys" with Michael Palin hosting.   This first video is about the history of the train system in Great Britain and is probably the most authentic piece on the topic by Palin because he is working off material in his early life when he was a train fanatic.  One can not help having some nostalgia for 1980 when watching this. 

 

Obama to have professor of african american studies read at his inauguration

Sunday, December 21st, 2008

Professor of African American studies?  What the heck do you do with a degree in African American studies?  It seems to me the reason why the United States has the economic problems that it does is that too many people are studying the equivalent of African American studies.   Whether it be basket weaving or going to college on a sports scholarship you are not likely to get out of school and be a big producer of money velocity.

Indeed I feel this is a bad omen for Mr Obama’s term as presidency.  Let us compare this with who would speak if I was being inaugurated.  I can think of many people much more interesting than someone who studied how to teach others to become wards of the state.  How about Leon Lederman Nobel laureate for physics ?   Any engineer of any type would be a welcome message to the people.  My message would be get studying because if you do not create gross national product then you are nothing.  Because it is true.

The tide of history is not pushed by the diversionary figures of entertainment or agitprop.  The tides of history are driven by technical people and by great economic figures of industry.  If you are not one of these you are a follower no matter how you try to be otherwise.

Want to use Wind Power? You can by building it yourself

Monday, August 25th, 2008

For you environMENTAL cases you can build your own wind generator.  You can see all the information you need here: www.otherpower.com/otherpower_wind.html

Very interesting and fun designs.  What’s stopping you liberals?  The earth is warming!! How can you NOT build one of these? 

The nice thing about this set of likely Bush – Haters is that at least they appear to be walking the walk instead of just telling me what I ought to do.  And they appear to be scientifically truthful…. it’s not likely to be cheap or easy or cost effective if you already have grid power.

The engineer in me wishes he had time and space to build one.

D Wave Founders blog

Monday, August 11th, 2008

I am currently researching if D Wave has a public interface where one can submit jobs to one of their quantum computers.  I have not found if they have yet but I have found one of the founders blog here:  http://dwave.wordpress.com/

Seems to be throwing one machine open to the public would be a good idea.  Some jackass somewhere will use it for something it was totally not meant for and it will turn out to be the best use for it.   Or maybe I am just saying this because I want a chance to have a few runs on it.

UpDate( 08-13-2008): D-Wave has a mocked up system with classical solvers where you can become familiar with their user interface.  You can sign up here: sandbox.dwavesys.com/orionui/

Edward Farhi talk on Adiabatic Quantum Computing

Sunday, August 10th, 2008

Good presentation on adiabatic quantum computation.    In information theory class I learned that by using the Laplacian form and maximizing entropy you can find the description of physical systems.  The adiabatic minimization will work well in these scenario.
