We present an original scheme to rotate at will one electron spin trapped in a quantum dot by just acting on pump-laser polarization: The quantum control is based on the virtual excitation of electron ...
2. Efficient Toffoli gates using qudits
(Uncategorized/Publication)
... the number of controlled-sign gates required to implement a Toffoli gate can be reduced to just 3 if one of the three quantum systems has a third state that is accessible during the computation-i.e., is ...
3. GCD of random linear combinations
(Uncategorized/Publication)
... with gcd(a(1),..., a(m)). This naturally leads to a probabilistic algorithm for computing the gcd of several integers, with probability 6/pi(2) + o(1), via just one gcd of two numbers with about the same ...
... is achieved via resonant microwave pulses as in liquid-NMR quantum. computation while the qubit readout and reset is achieved through trapped-ion fluorescence shelving techniques. By adjusting the microtrap ...

... at lambda = 1.55 mum. It is found that the interdefect spacing can be adjusted to yield a flat top response, with close to 100\%, transmission and 45 degrees Faraday rotation, for film structures as thin ...
... in a gain in the initial EO coefficient. This model also reveals that the resulting EO evolution in a thermally poled germanium-boron codoped fiber can be attributed to the movement of just two ions of ...
Danny and me just had our paper on quantum goblins published in PRA. This is the first publication from my Phd, and my first PRA. After comments from the editor we changed the name from (the arXive version's) ...
Just saw this... http://www.youtube.com/watch?v=VeeXTmVGoxs&feature=fvsr Now if I can can this for my iPhone I would have endless fun!    ...
... chapter and sections. All of this really only works if you are using pdflatex to make your pdf document. If you want to make a pdf copy for black and white printing just leave out "foronline". ...
... killed him and why? Please don't post the answer to this one here, send me an email, tell me the answer or just keep it to yourself I will give the answer next week. And don't forget 2000!mod2003. ...
12. PhD Projects on offer
(Opportunities/Opportunities)
... of spatially entangled photon sources Dr. Gabriel Molina-Terriza, Prof. Jason Twamley Nowadays we can generate states of light that couldn’t even be imagined just a few years ago. We can control ...
I just arrived in Waterloo University yesterday with Johann and Lauri. We join Aharon who came earlier to stay in the same student housing. It's real summer here: warm, humid, and rainy. This morning, ...
14. Jason made me do this ;)

... it just is. It always makes me excited, even if I just go to pick someone up, I feel funny around the airport. And here is where it all begins.   Level 2: New people and new places. It's always ...
I just came back from the CEWQO (Central European Workshop for Quantum Optics) 2009, where Prof. Breuer introduced an interesting approach to deriving a master equation for a non-Markovian open system. ...

... to quantum information and quantum computation by Michel Le Bellac" has a good 10 pages) However, one could glean a lot of knowledge from  powerpoint talks posted online.  Here are just a couple ...
18. Porting C code into Matlab
(MyBlog/MyBlog)
With a bit of editing, it is possible to run C (or Fortran) programs as Matlab functions. (It should also be possible to do it the other way around.) What has to be done is just modifying the original ...
19. Making big .EPS files small
(MyBlog/MyBlog)
... just going to give a quick run down of how I did it on a Mac. It should be fairly similar for Linux. In theory: Change EPS files to JPEG (JPEG compression makes them MUCH smaller)  Change JPEG back ...
20. Topological Quantum Science
(Research Themes/General)
... consequences amoung them being that this state of matter is characterized by more than just the energy and few body correlation functions but also by the entropy of subsystems in the ground state. Early ...
