We have a Python library called pyQuil [1] for writing high-level programs for quantum computers. The "assembly" you mentioned is Quil [2], which we don't expect most users to use directly. Other high-level languages for qua

I think this is the best question so far :) After an informal poll of ~30 of our scientists/engineers, ~8 said they subscribe to the many-worlds interpretation [1] [2] of quantum mechanics. To be honest, this is a discussion that comes

It seems like we should be more careful when saying "exponential" increase in computational performance. For many quantum algorithms, the speedup is actually superpolynomial [1] [2]. In some sense, this is due to the fact that t

Yes, we provide the QVM [1] as a cloud-hosted service and it's capped at 30 qubits for now. [1]: http://pyquil.readthedocs.io/en/latest/qvm_overview.html

We couldn't make the binaries small enough for our current device ;) We use Linux heavily to develop our own quantum OS. Programs written with Forest targeting the QPU [1] pass through the quantum OS, which runs on the control systems

Great question. Both the IBM Q experience and Rigetti Forest allow users to write quantum algorithms with Python that can execute on real quantum hardware. Forest is different in 3 main ways: 1. Forest was designed with near-term applicatio

I'm Dan and work at Rigetti as a software engineer. Be sure to see this post about Forest 1.0: https://news.ycombinator.com/item?id=14595290 See this discussion there for a Q/A, or start one here!

The screen DOES cause the superposition to collapse. It just does so after the electron was able to interfere with itself. This causes the probability distribution for the collapse to be different than it is in the presence of a detector at

Agreed - I used Mermin's book in my undergrad. Not as comprehensive as Nielson and Chuang, but I love Mermin's style. The lecture notes you mentioned are here: http://www.lassp.cornell.edu/mermin/qcomp/CS

Pilot wave theory requires non-local hidden variables. Only local hidden variable theories have been shown to be impossible. In non-relativistic situations, Bohemian mechanics (pilot wave theory) makes the same predictions as more mainstrea

IIRC reversible computations only take zero energy if you perform them infinitely slowly.

Very strange to see this here. I was personally blown away. Did you watch the right video? And even if you dismiss the quality, there's still a huge opportunity to use this to inspire "real" art. It's bigger than a fad.
