What’s under the hood of a quantum computer?
- chovybizzass 6y agovery large hamsters.
- dang 6y agoCould you please stop posting unsubstantive comments to Hacker News? You've been doing it repeatedly and we're trying for something else here. This is particularly important when a thread is new because threads are sensitive to initial conditions. More on that here: https://news.ycombinator.com/item?id=26419770 https://news.ycombinator.com/item?id=26419770.
- mpoteat 6y agoThank you for keeping Hacker News a clean and a productive environment for rational discourse. I see you a lot across posts and I'm not sure how much automation you use, but it's clear that you put in an extraordinary amount of effort in tending this garden. Thanks dang.

- mikewave 6y agoVery cool. We have a 3D tour of the D-Wave quantum computer here for anyone interested: https://content.dwavesys.com/WebGL/D-Wave/index.html https://content.dwavesys.com/WebGL/D-Wave/index.html
- suifbwish 6y agoI wonder if quantum computing is possible in biological systems.
- elmomle 6y agoThere's certainly evidence of quantum biological machinery--it is believed to be behind the efficiency of photosynthesis, for example: https://www.sciencedaily.com/releases/2018/05/180521131756.htm https://www.sciencedaily.com/releases/2018/05/180521131756.h... And why not? Life doesn't care if a physical effect is quantum or not!
- galaxyLogic 6y agoIs it possible that there are quantum effects in the brain too? And could that perhaps explain schizophrenia? (only half-joking)
- Ma8ee 6y agoThat is apparently wrong [0]. I recently heard a podcast with some of the scientists involved. They were very frustrated with how hard it had been to get any attention at all for the negative result compared with the original research.

- tobmlt 6y agoSandia is doing a trapped ion quantum computer experiments? Very cool — I did not know. Good luck!
- unobatbayar 6y agoThanks for sharing!
- davidw 6y agoPretty fascinating stuff, even if I don't get all of it. I wonder how much reliability and 'decoherence' and some of the other problems will improve over time? There's a joke there somewhere about finding a dead/live cat when you open the hood, or broken/working computer, or something along those lines.

- hazeii 6y agoA couple of years ago I got to push some trapped ion's around in the quantum computer under development at the University of Sussex [0]. Very cool, seeing the glowing ions on a monitor and moving them in 1-micron steps via the cursor keys. You get to realise how sensitive this stuff is when you hear it took them 3 weeks to track down a single hair that was contaminating their (extensive) vacuum system.
