This paper is about fault injection on real Intel CPUs, resulting in interesting primitives such as instruction skip. Read the uasc.cc/proceedings2... and/or attend uASC in Leuven to learn more!

So What Do We Know QC To Be Good For?
- Simulating quantum physics and chemistry
- Breaking current public-key encryption (RSA, DH, ECC)
- Eventually, modest (square-root) speedups from Grover
- We’ll have to get lucky for most other applications!
(The world has been systemically lied to about this)

This seems like a good idea until you think it through - there are many reasons solar panels go on roofs at an angle, and not flat on the ground, with plenty of dirt, vegetation, mechanical stress, … So less flashy but more practical would be to eg use station roofs. See also youtu.be/7vItnxhWRqw
