It's early. And companies and governments achieving some sort of competitive advantage would be playing these applications close to their chest to keep their advantage.
QC has led to significant prevention of loss-of-life, loss-of-equipment, and territory gains in battlefield applications. Encrypt/ Decrpyt was already mentioned as a use case. None of these dual-use practical applications are public.
QC is good at "analog" computing: applications where you are more interested in potentials than in 0s and 1s. That lends itself to material design problems. There are applications in battery design and catalytic converter. F1 teams have some interesting fluid dynamics and laminar flow problems where QC was instrumental to test hunches fast. It's not so much about exact compute of solutions, but how to verify a first guess fast to then use traditional software. One could argue this is a niche application, but not if you consider marketing and streaming rights and advertisement impact. A similar approach is used for drug discovery.
None of these "practical" applications are talked about - they are a competitive advantage of commercial enterprises. But if you care for a proxy you could look at any significant hires 1-2 years ago with PhDs, compute, math experience in relevant QC fields. And you would be surprised to see some companies hiring more than 20-30 people in that field (and not just Google or Amazon etc.). That's an FTE expense that could just be hedging of a large company; but could also be product design; and is definitely more than a test balloon or R&D pet project. Some of these companies are known for industrial adhesives, specialty cement, or "green" base oils for lubrication and cooling and cutting. so not all tech companies or big pharma.
Fun - I like the assistants! But: how do you share an anonymous IO page with a link ... anonymously (other than the random link)? What's the difference between creating a pseudonym on twitter and also a pseudonym on medium etc.?
If a "lightfield" is projected into your eye, how do you cope with (additive) light input from the real world?
if it is real, will there be a law to tag 'virtual' things so i don't accidentally kill a real person when I thought that was part of my game? You know how congress or the senate would design that one ;)
I actually don't unlock my laptop but instead take a look at my "cheat sheet" of "What do I want to achieve". It consists of three pages: (1) a personal code of conduct and ethical guidance (a long list of copy and pasted things from all over the web as well as things I've read as well as things I've seen and experiences and learned over the years that I think I should do); (2) a long-term goals (rather static); (3) weekly objectives (NOT tasks!).
Before I commit myself of spending time of something I ask myself: how does that contribute to any of my goals for this week, or any long term goal, or is in line with my ethics code? I then make a list of things I need to do today or want to learn or think would make sense for today.
THEN I open my calendar and task list and check and prioritize my activities: decline meetings that are not aligned with my objectives; prioritize tasks that are essential for today or this week; defer tasks that are not urgent; make sure I have enough time in the day.
I also know which hours of the day I am most productive for coding vs. reading vs. relaxing vs. writing vs. learning -- trying to mill through Excel Sheets at 2pm is a bad idea.
This morning routine also prevents me from procastination and "reading up" on "interesting sites" -- once you realize what's ahead of you today, how that contributes to something you always wanted to do or learn, you probably realize how to spend time better and feel more satisfied.
