### Collapsing the Polynomial Hierarchy is ‘Dangerous’

#### by noospheer

Not only is P vs. NP the defining question of our field; it’s one of the deepest questions ever asked for which we’d know how to recognize an answer. (In other words, one of the deepest questions in NP.)

Aaronson, p.1

A rigorous and therefore undeniable mathematical proof demonstrating a collapse of the polynomial hierarchy (PH) has a large number of big implications for the world beyond math and science.

- First, in terms of math and science; a successfully collapsed PH is closely related to efficient classical emulation of quantum systems (via post-IQP circuitry); in other words, regular computers may be fully capable of being quantum computers. The mainstream understanding — as alluded to in the post-IQP paper — is the rather naive one that quantum computation requires processors which demonstrate
*quantum effects*as we currently define them. The mainstream is missing the point: computer science is, at its core, linguistics. If we know the math (which we do quite well), and assuming the Church-Turing thesis is actually universal, then we*just*need to teach our machines how to run the calculations (by**writing**insanely great code). One is now free to imagine a planet (such as this one) suddenly bustling with quantum computers, which include your laptops, cell phones and satellites. tada! [For the skeptic: W, X, Y, Z, 1, 2, 3 (pIQP demands a linear sample rate for PH collapse) It is also important to note that a collapse of the PH does not necessarily imply P = NP, however the two are inextricably related and are both considered ‘improbable’] - What about our institutions/ourselves — specifically with regard to information privacy? The only factor which maintains a state of separation among entities in a shared space is unshared data. That said, with 1. in mind, the first thing a security guy/gal might consider is a ubiquitous encryption method called RSA being compromised. [Fun Fact: RSA was published 7 years after P v NP was formalized.] Long story short, if 1. becomes a reality, then the invincible armor shielding governmental, financial, corporate, and an increasing amount of personal data from ‘adversaries’ — suddenly meets Kryptonite.Please consider this another
**early public****WARNING:**Any software we write which runs Shor’s factoring algorithm (or any QA) in polynomial time (efficiently) may likely render some encryption methods crackable, and will be published and distributed as a proof under language outlined in the Free Berkeley Software Distribution license. - 2. outlines the atomic tip of the iceberg. Implications for medicine, energy, and time travel abound as well.

Dangerous, or benign? Probably both.
