To illustrate, nothing along the lines of “the universe is quantum because it needs to be holistic, interconnected, full of surprises, etc.

Before I embark on my survey project, I’d better know if there are promising ideas that I’ve missed, and this blog seems like as good a place as any to crowdsource the job.Īny answer is welcome, no matter how wild or speculative, so long as it honestly grapples with the actual nature of QM. The purpose of this post is to invite you to share your own answers to Q in the comments section.

crucially, I don’t think I already know the answers, and merely need better arguments to justify them.

I don’t dismiss either Q1 or Q2 as silly and.

And also because, besides having spent 25 years working in quantum information, I have the following qualifications for the job: I want to do it because I regard Q as one of the biggest questions ever asked, for which it seems plausible to me that there’s simply an answer that most experts would accept as valid once they saw it, but for which no such answer is known.

I want to do this for my own sake as much as for others’. So, I want to write something about the space of credible answers to Q, and especially Q1, that humans can currently conceive. Q1 therefore stands, to me at least, as the more mysterious of the two questions. I could spend half a semester teaching theorems that admittedly don’t answer Q2, as satisfyingly as Einstein answered the question “why the Lorentz transformations?,” but that at least render this particular set of mathematical choices (the 2-norm, the Born Rule, complex numbers, etc.) orders-of-magnitude less surprising than one might’ve thought they were a priori. Q2: Assuming classical physics wasn’t good enough for whatever reason, why this specific alternative? Why the complex-valued amplitudes? Why unitary transformations? Why the Born rule? Why the tensor product?ĭespite its greater specificity, Q2 is ironically the question that I feel we have a better handle on. Q1: Why didn’t God just make the universe classical and be done with it? What would’ve been wrong with that choice? If you want, you can divide Q into two subquestions: Q: Why should the universe have been quantum-mechanical? I’m feeling a strong compulsion to write an essay, or possibly even a book, surveying and critically evaluating a century of ideas about the following question: Thus, whatever I wanted to accomplish in my intellectual life, I should probably get started on it now.By my age, Einstein had completed general relativity, Turing had founded CS, won WWII, and proposed the Turing Test, and Galois, Ramanujan, and Ramsey had been dead for years.

Despite my self-conception as a nerdy little kid awaiting the serious people’s approval, I am now firmly middle-aged.This, perhaps combined with covid, led me to several indisputable realizations: In the past few months, I’ve twice injured the same ankle while playing with my kids.
