We're probably decades away from Shor's algorithm. Right now we're mostly dealing in the realm of "Noisy Intermediate-Scale Quantum" machines (NISQ). The abstract of this paper gives a good summary of where we're at: https://arxiv.org/abs/1801.00862 The "operating system" has little to do with accelerating that (outside of maybe cutting out some development cost + time), though in theory they can provide some algorithms and optimizations that minimize noise and decoherence.

There is no known useful application of current quantum computing (so-called NISQ, for Noisy Intermediate-Scale Quantum). It is an open question whether there is any, see https://arxiv.org/abs/1801.00862.

Hopefully we will see results way before we start breaking RSA. It looks like people are targeting applications in quantum chemistry [1]. Also, Dyakonov's criticisms are toothless, see comments here [2]. [1] https://arxiv.org/abs/1801.00862 [2] https://scirate.com/arxiv/1903.10760

For the skeptical, there are two quantum computing job tracks which can operate independently for the next while: (1) The engineering and basic physics research necessary to build a real, working quantum computer of high enough quality (low error rate) and size (number of qbits) for real-world use. Scott Aaronson believes we won't have a sufficiently-advanced quantum computer to, for example, run Shor's algorithm against a real-world key size for at least 15 years. (2) The development of quantum algorithms, error-correction schemes, cryptography, and as-yet-unknown use-cases; the…

I'm a little worried about these companies over-hyping the current state of capability. For sure, this is an exciting time though, and I am certainly optimistic about the long-term prospects. Anyone interested would do well to read [0] [0] https://arxiv.org/abs/1801.00862

Yes, there are two reasons that python is an ideal tool for quantum computing libraries at the moment. - In the NISQ era [1], circuits have limited depth and size. It doesn't matter so much which language (or even algorithm!) you use when N<1000. - Simulating a circuit is expensive, but all the heavy lifting can be delegated to highly optimized C code. The most expensive part of Cirq's simulation is (or soon will be) a call to `numpy.einsum` [2]. 1: https://arxiv.org/abs/1801.00862 2: https://github.com/quantumlib/Cirq/blob/24638f234704686c4bb6...
