Get to know the unique properties of quantum computers and the obstacles that have prevented this theoretical technology from becoming a reality.
--
Quantum computers could eventually outstrip the computational limits of classical computers. They rely on the behavior of atomic and subatomic particles, whose quantum states are incredibly fragile and easily destroyed- which is why this technology remains largely theoretical. How would quantum computers work, and are they really possible? Chiara Decaroli investigates.

I was giving out helpful links, but it won't allow me to do that now, so I made playlists. Check my youtube channel by right clicking on my avatar / picture icon to the left of this comment, click "open in a new tab", find the subscribed youtube channel called Technology Research with the playlists, find the playlists and click on "created playlists", I think some of them are hidden. And then click on the title / text of each playlist, not on the pictures. I would send a link, but youtube is being toxic I think, because when I log out and come back to the same videos, my comments with links aren't there, but when I log back in, they are there. Nothing like talking to yourself when trying to be positive and interested, and just trying to share the info. Please check out all the videos under each playlist from top to bottom in that order, and please check out all the playlists, and share.

Meanwhile Trapped Ions are like AMD CPUs before Ryzen came out, where they lose to Superconducting Circuits IPC-wise, but can theoretically make up for it by continuously adding more and more cores aka Ion Traps.

to those who dont get it. quantum states are infinite. so when you superposition 2 qbits they can run all combination specified by 2 bits. since total combination of 2 is limited more needs to be superpositioned. so they all process given parameter in parallel instantly. The challenge however is superposition more qbits is hard due to many disturbances in atmosphere.

Current computers work using two states on and off - the on state being the 1 and the off state being 0 so other than quantum computing we have no way of increasing the number of states
