Will Google make a "watershed" announcement about quantum computing in early December?

Quantum computers make use of the properties of quantum mechanical (as opposed to classical) systems to solve certain problems much more efficiently than a classical computer can.

For example, using a quantum computer, large numbers could in principle be factored into primes using Shor's algorithm in polynomial time, versus near-exponential time for classical computers; this latter inefficiency underlies the security of many encryption schemes.

A prototypical quantum computer is composed of N "qubits," or quantum mechanical bits. Keeping these qubits operating as a closed system that retains its quantum character (without "decohering" via interactions with the environment) is a difficult challenge for more than a handful of qubits.

However, there have been a series of claims by D-wave systems that it had constructed quantum computers of a different type with thousands of qubits. These machines cannot enact generic quantum compuing algorithms like Shor's. However they are claimed to be dramatically faster at certain optimization problems.

There has been widespread skepticism towards D-wave's claims, with some asserting that D-wave's system does not use quantum mechanics at all, and others arguing that even if it does, that this provides no real speedup relative to classical computers.

Nonetheless, Google has purchased D-wave systems for testing, and Google, NASA and others recently signed a multi-year agreement to test the systems.

On November 11, a D-wave board member has announced that there will be a "watershed announcement" at Google on Dec. 8 about quantum computing. Will this occur, and be a major change or breakthrough in computing or quantum computing?

The question resolves as "true" if either the New York Times or Washington Post carries a story based on Google's Announcement on the front page prior to December 15, 2015.


Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available. With tachyons you'll even be able to go back in time and backdate your prediction to maximize your points.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Note: this question resolved before its original close time. You earned points up until the question resolution, but not afterwards.

Thanks for predicting!

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
