While this is true, if your pc is secure and you don’t install crap then this is not going to be a major issue for the vast majority of people. Both desktops have their own security flaws but always the number one flaw is the user.
Keep systems up to date, do not side load software from outside well managed official package systems, use strong passwords, use encryption etc. This counts for far more than the various security flaws and fixes that constantly come and go with any system. If you don’t give bad actors a route into your system to exploit flaws then you are generally OK.
Like the screen copy flaw would need someone installing software that would exploit that - possible but unlikely in a well managed environment with a good robust distro.
And it’s worth saying that generally Linux remains less targeted than Windows and Mac for malware. That does not mean people should then be lax in their behaviour but it’s a better starting point for being secure if you look after your Linux install properly.
As stable as that dime is, it’s utterly useless for all practical purposes.
What Google is talking about it making a stable qbit - the basic unit of a quantum computer. It’s extremely difficult to make a qbit stable - and as it underpins how a quantum computer would work instability introduces noise and errors into the calculations a quantum computer would make.
Stabilising a qbit in the way Google’s researchers have done shows that in principle if you scale up a quantum computer it will get more stable and accurate. It’s been a major aim in the development of quantum computing for some time.
Current quantum computers are small and error prone. The researchers have added another stepping stone on the way to useful quantum computers in the real world.
