MD quantum computers

Hello lammps users,

Although this is not a LAMMPS related question, I would like to hear the opinion of Axel on a doubt that I have. Recently I read that a high programming lengauge was created for quantum computers http://www.newscientist.com/article/dn23820-new-language-helps-quantum-coders-build-killer-apps.html. My questions are: How realistic is to implement a MD code such as LAMMPS in a quantum computer? , How efficient or faster would be a simulation on a quantum computer … i.e would it be feasible to reach simulation time scales of milliseconds or seconds? . Thank you very much Axel for your answer and remove my ignorance …

Hello lammps users,

Although this is not a LAMMPS related question, I would like to hear the
opinion of Axel on a doubt that I have. Recently I read that a high
programming lengauge was created for quantum computers
http://www.newscientist.com/article/dn23820-new-language-helps-quantum-coders-build-killer-apps.html.
My questions are: How realistic is to implement a MD code such as LAMMPS in
a quantum computer? , How efficient or faster would be a simulation on a
quantum computer .. i.e would it be feasible to reach simulation time scales
of milliseconds or seconds? . Thank you very much Axel for your answer and
remove my ignorance ....

sorry, but i am in solid nerd territory on the geek vs. nerd scale
( http://slackprop.wordpress.com/2013/06/03/on-geek-versus-nerd/ )
and this is a very geeky topic and thus not really my thing.

here is my perspective on these kind of things:

quite a few of the people that i deal with in my capacity as an
educator/consultant in high-performance computing still evade
multi-threading and vectorization and struggle with parallel thinking
and many other things that impact efficiency on current computers.
they would *love* to use anything that gets them an faster answer for
as long as you can program it in plain fortran or there is a
ready-to-use software package for it. consequently, i have seen - for
example - enthusiasm for accelerators evaporate instantly, when people
realize that it takes more than just changing a few lines of code here
and there, but a significant change in how to view algorithms. with
that in mind: i will only get excited about new technology if it has
more than just "the potential to change" going for it. these things
happen all the time and only a small percentage sticks, since
everything is nowadays so much driven by hype and not fact.

ciao,

Hi,

a geek could love this article: http://www.tandfonline.com/doi/abs/10.1080/00268976.2011.552441 , that may be related to MD.

Dear Oscar

I'm embarrassed to admit that I entered physics graduate school 14
years ago partly because I also got excited about the impending
arrival of quantum computing. These days I feel differently. I would
not read an article in newscientist and get your hopes up that you
will be able to use one in the next decade.

Quantum computers answer different kind of questions. If one did get
built, then it would force us to think about the way we simulate the
world in a completely new way. It is beyond premature to worry about
how to get LAMMPS to run on a quantum computer, or to ask how much
faster it would be.

But they are cool.
Cheers
