Quantum Researchers Achieve 10-Fold Boost In Superposition Stability (thestack.com)
An anonymous reader quotes The Stack: A team of Australian researchers has developed a qubit offering ten times the stability of existing technologies. The computer scientists claim that the new innovation could significantly increase the reliability of quantum computing calculations... The new technology, developed at the University of New South Wales, has been named a 'dressed' quantum bit as it combines a single atom with an electromagnetic field. This process allows the qubit to remain in a superposition state for ten times longer than has previously been achieved. The researchers argue that this extra time in superposition could boost the performance stability of quantum computing calculations... Previously fragile and short-lived, retaining a state of superposition has been one of the major barriers to the development of quantum computing. The ability to remain in two states simultaneously is the key to scaling and strengthening the technology further.
Do you ever wonder what the world will look like when everyone has their own personal quantum computer?

Could we please get to work on getting everything on the web compatible with a stateful encryption scheme (out of band preshared keys and signing schemes that aren't entirely reliant on any form[1] of asymmetric cryptography) now ? Instead of waiting 10-20 years and then suddenly finding out, oh crap, some government has finally has built a quantum computer powerful enough to crack RSA/ECC?
No? Oh well. I tried.
1. Yes yes, there are some asymmetric schemes that aren't known to be vulnerable to efficient quantum algorithms, but there will always be a buttload of lingering question marks over any scheme that doesn't involve shared secrets.
The team ran a benchmark on one of their quantum computers to accurately measure the new increased speed.
Unfortunately, they can no longer find the computer to repeat their test.

At the rate and direction we're going, it'll be a dystopian future world where you can't even take a dump in the privacy of your own home bathroom without some government spook having a terabyte of data collected from the 'event'. Of course, that being said, it's just as possible that while we'll have record amounts of surveillance and spying on everyone all the time, everyone will have access to continually morphing high-end encryption driven by their own quantum computers, creating a 'balance of power' on both sides of the equation.
Or, just maybe, we, as a race, grow out of this anal-retentive, must-watch-everyone-all-the-time, anxiety-driven, infantile stage of our social development, into a New Age of 'Live and Let Live' on all sides of all equations. Yeah, yeah, I know. Let a guy dream, will you?
