Check out https://www.rigetti.com/ if you want to work with python.


we need to stop calling things quantum that are not quantum - its confusing


I got confused too.

We can't stop people from naming their projects/products the way they want. However, I think headlines in HN should be editoralized a bit to provide context, followed by the actual headline from the webpage.


Are there other examples of startups tackling problems that were only addressed by departments of larger problems and those startups then using their focus as an advantage?


What is the difference between the approaches that Rigetti and say Google and IBM are taking?


I'm a software engineer at Rigetti, so I'll talk a little bit from that perspective.

One thing we are really emphasizing is having a full stack of software to enable hybrid classical/quantum computation. We believe that leveraging current computing resources as much as possible in a quantum computation will be important for near-term algorithms. Quantum algorithms such as the quantum approximate optimization algorithm very naturally fit into this hybrid computing regime.

There are lots of details about our quantum computing architecture which differ from the other players out there. There are different kinds of qubit-qubit interactions that we do compared to IBM. I will defer questions about these to other folks and our recently released white papers [0, 1, 2, 3].

From a company standpoint, our goal is to build the most powerful computer. Not anything else. We don't do ads. We don't build business machines. We build quantum computers and make them available with software. When you depend on it to survive, you definitely work a little bit harder and smarter to achieve your goals.

Interesting - Is there a good reference which describes the Born-Oppenheimer approximation in terms of parallel transport?


Harvard student here - I would like to know as well...


Montreal, seriously. I grew up in Cambridge, Montreal blows the Boston area art/culture/music scene out of the water ;-)

5 hour drive but USD goes pretty far these days up in Canada; definitely worth a road trip to get a taste of Europe in North America.


Somerville :)


As a Somerville resident... what? We're cool? Are you guys talking about that one bar in Davis with the great cookery, or the Tuesday death-metal night on Highland Ave or Slumerville Brewery or what?


Probably thinking of Union Sq :) Even the New York Times thinks Somerville is hip: http://www.nytimes.com/2014/10/05/travel/out-of-the-shadow-o...


I was! I live on Bow St/Somerville Ave. :D


Hey now. You can get some good eats at Sarma and Highland kitchen.


I've never been to Highland Kitchen, but shhhhh, we do not talk about Sarma!


This is actually true.


Eh. Somerville is real quiet, except when HONK or whatever are going down. I enjoy it, but it's not that kind of scene.


Visit Aeronaut on a Saturday.


I haven't been there in a while. Maybe I'll do just that...


Small mountain towns that will go unnamed.


Bushwick, Brooklyn.


Maybe 5 years ago, but Bushwick has been absorbed into the real estate/media industrial complex. Look at KCMO or Atlanta instead.


I like the way you think. How could someone determine if this occurred? Rocket sabotage seems like a rather perfect crime, very little evidence is left afterwards.


I wonder if Quantum Annealing would also be applicable.


I think in theory it is possible by unary encoding attributes of the five houses then defining the appropriate weights according to the constraints.

In practice it might not be possible to map the resulting graph on the D-Wave's architecture, I can't find any good documentation on the D-Wave though.

The scaling on the simulation of the nanowire was dismal. Having effective quantum simulation would make such a tremendous impact on semiconductor development.


The scaling behaviour is actually surprisingly good. The time to simulate quantum mechanical systems generally grows exponentially with the number of states, i.e. the number of atoms in this case, but the listed running times grow only somewhere between linearly and quadratically with the number of atoms.
