What are the important factors in the choice of laser sources for quantum information/metrology applications
1. Specifically if I want an pulsed q switched Nd-Yag with 2,3 4 harmonic generation.
2. Repetition rate
3. Peak power for producing entangled photons by PDC
etc
4. Are low power diode lasers sufficient
I am about to complete my B.Tech ( Bachelor in Technology) in Computer Science from NIT, Surat, India. I am highly interested in Quantum Computing and for past two year I have been giving considerable time for QC apart from my regular curriculum which has no direct connection with Quantum Computing. I have been learning myself with aid of video lectures and survey papers in Internet and also have brought Books ( Nielson Chuang; Kitaev et al).
Dear Readers.
First thing I'd like to mention is that I'm from Poland [middle-European country]. I can tell You, that my Polish language skills are quite good [You can believe me, or not ;p]. I'm high school student [soon-to-be 18 - in November] and the one who wants to help wiki-quantiki readers from Poland by translating it to Polish.
Why am I writing on forum, not translating right now? It's quite easy - I need some server space for it.
I have got to propose a narrowed down area of interest for my undergraduate thesis on Quantum Information. I am having troubles with that. Could someone please help with that? What are the recent research trends in QI? I am more interested in quantum information processing than on implementation of quantum computing devices.
It is well-known that the Shor’s factoring algorithm uses two quantum registers. Recently, by investigating the algorithm with three registers, the authors (http://doi.ieeecomputersociety.org/10.1109/ISISE.2009.86) argued the claim that the Shor’s algorithm runs in polynomial time is false, because Shor had wrongly treated a joint probability as a conditional probability. The argument is very short, and seems sound to me. If so, that’s big news.
I figured I'd pass along the link to my quantum computer programming blog: http://mpurkeypile.blogspot.com/. I'm primarily focusing on the computer science side of QC as well as any related topics that spark my interest.
what's your opinion about the de Finetti representation as a good measure of entanglement?
i am looking for some intrested persons to work on the de Finetti representation in quantum optics and cavity qed or extending
their applications to finding a good measure of seprability.

Hi,
I am just curious whether to increase the number of qubits at a QC simulator is necessary or not.
Currently, most QC simulators are running in a single CPU environment. However, I am thinking about implement a QC simulator in an environment which could significantly increase the number of qubits so that we can try more strategies to use the power of quantum computers when one day the real QC comes true.
Theoretical work on quantum computation usually assumes the existence of
units that perform highly idealized unitary operations. However, in practice these
Does somebody knows how to project a discrete-time quantum walk with a Grover coin on the hypercube onto the line? I was trying to reproduce this paper (http://arxiv.org/abs/quant-ph/0210064)"A Quantum Random Walk Search Algorithm" by Neil Shenvi, Julia Kempe, K. Birgitta Whaley, and I cannot understand how does it manage to do that. I'm posting as an attachment to this post the part of the paper that I cannot solve (I hope it doesn't violate any rules of the forum, since it is available in quant-ph).
Thanks in advanced!!
