| SilverSolder:
1) Has anyone successfully explained how quantum computing works in a way that an intelligent 12 year old could understand? 2) What is it that is holding quantum computing back? What is the limitation that we can't seem to get past and "make it real"? 3) Any ideas for simple quantum computing experiments that we can do in our home labs / basements / kitchens / garages / caves? |

@eevblog: Some more for the hat. Thanks. There are many ways to implement a qubit. Which of these methods, if any, will result in the construction of a reliable quantum computing platform? Other than cyptography, what computational problems are quantum computers more suited when compared to electronic machines? What are the biggest engineering hurdles to quantum computing, and how are these being solved? So how exactly do you program a quantum computer? What would be quantum computings' killer application? |

There are a ton of videos on YouTube and I tend to head toward anything by computerphile so I searched for 'computerphile quantum computing'. As an offshoot, there are dozens of other videos offered for viewing. Somebody must think there is a future in quantum computing, Microsoft and Google both have labs working on the subject. Probably the next version of Chrome or Office... As to home quantum computing, that probably won't happen until there is home delivery of liquid helium. The device likes being cold. Like a fraction of a degree above absolute zero. That's a limitation today in the same way that Eniac used vacuum tubes. Within 20 years, transistors ruled, heat dissipation was substantially reduced and speed increased. Seventy odd years later we have some fairly productive systems. Cryogenic computing started back in '61 at IBM https://www.electronicsweekly.com/blogs/mannerisms/memory-lane/ibm-launch-cryogenic-computer-2017-09/ If you want to bend your mind around "spooky action at a distance", quantum entanglement is the ultimate in distributed computing. In theory, particles can simultaneously change state when displaced across the universe. There's a lot of particles in our universe, it would make a heck of a computer. https://www.sciencemag.org/news/2018/04/einstein-s-spooky-action-distance-spotted-objects-almost-big-enough-see |

I've seen "Devs" https://en.wikipedia.org/wiki/Devs ... ask them for next weeks Lottery numbers. You could ask them about error rates... and when to expect a useful and reliable result from one... .... and who is investing the cash... spooks breaking crypto? PS And do they own a cat? Do they keep it in a box? [I bet they have never heard that one before.. :-DD ] |
