I second a few people on here: You will probably need to learn quite a lot of math if you did not study physics or math. In order to understand quantum physics, you will need to understand what vector spaces and Hilbert spaces are, have a good grasp of calculus (derivatives, integrals should be no issue for you), a good understanding of Fourier analysis and statistics.

Then, you should probably take a class in the basics of quantum physics which will lay the foundation for you to understand quantum computing.

I really really loved Nielsen and Matushak's Quantum country. https://quantum.country There are two reasons I like it. There is no mumbo jumbo about polarising filters and "look how mysterious" it is. No. They concentrate on very simple linear algebra and work with it. Second, they make a convincing argument that when you memorise a bit of material, it makes it intuitive. So they incorporate spaced repetition to cont…

It's a good source if you know linear algebra. Beginners should know that there are no solutions to check your work.

if you're a comp-sci guy and just interested in understanding what it's all about Aaronson will be your favorite author: https://www.scottaaronson.com/barbados-2016.pdf

his blog is excellent (and hilarious) as well. https://www.scottaaronson.com/blog/

I'm a D-Wave employee, and our cloud service [1] is mature and available* today. You can sign up to get a free minute of QPU time (which turns out to be quite a lot; sampling a problem generally takes milliseconds of QPU time). Additional time is granted if you link your github account to your Leap account, and of course, you can pay for additional time. We've recently added an IDE [2], we've got tutorials [3] and Yo…

Is the debate about "D-wave isn't quantum computing its quantum annealing" still relevant?

I did a research project on the competitive landscape on QC few years ago and at least then it was a huge topic.

What are your thoughts?

This is great. Thank you!

Ryan O'Donnell from cmu has lectures to understand qc from an algorithm design perspective, so quantum information theory https://m.youtube.com/playlist?list=PLm3J0oaFux3YL5qLskC6xQ2...

His quote: "90% of the understanding of the quantum circuit model is achieved by reviewing three purely 'classical' topics: classical Boolean circuits; reversible classical circuits; and randomized computation"
