Welcome to c/news! Please read the Hexbear Code of Conduct and remember... we're all comrades here.
Rules:
-- PLEASE KEEP POST TITLES INFORMATIVE --
-- Overly editorialized titles, particularly if they link to opinion pieces, may get your post removed. --
-- All posts must include a link to their source. Screenshots are fine IF you include the link in the post body. --
-- If you are citing a twitter post as news please include not just the twitter.com in your links but also nitter.net (or another Nitter instance). There is also a Firefox extension that can redirect Twitter links to a Nitter instance: https://addons.mozilla.org/en-US/firefox/addon/libredirect/ or archive them as you would any other reactionary source using e.g. https://archive.today/ . Twitter screenshots still need to be sourced or they will be removed --
-- Mass tagging comm moderators across multiple posts like a broken markov chain bot will result in a comm ban--
-- Repeated consecutive posting of reactionary sources, fake news, misleading / outdated news, false alarms over ghoul deaths, and/or shitposts will result in a comm ban.--
-- Neglecting to use content warnings or NSFW when dealing with disturbing content will be removed until in compliance. Users who are consecutively reported due to failing to use content warnings or NSFW tags when commenting on or posting disturbing content will result in the user being banned. --
-- Using April 1st as an excuse to post fake headlines, like the resurrection of Kissinger while he is still fortunately dead, will result in the poster being thrown in the gamer gulag and be sentenced to play and beat trashy mobile games like 'Raid: Shadow Legends' in order to be rehabilitated back into general society. --

quantum computing is still in its very early infancy, literally NOTHING about it is stable yet. we can barely get them to run a dijkstra's algorithm, let alone anything actually useful. if you don't keep the processor cool enough it'll just kill itself, and we're already trying to mass produce them? putting that aside, quantum computers have a very small use case. most things it does, a classical computer can do better. who is the target userbase for this? the very saturated market of theoretical quantum physicists? i am very skeptical of this man
I know little, but wasn't microsoft hawking some quantum accelerator chip a while back? It was a card like a GPU that you put into a regular PC's expansion slot to do quantum calculations. Expensive (a few thousand) and still niche but seemed like a good enough proof of concept that you can mass manufacture these things
it was built off a theoretical particle (majorana) and as always they conveniently left out some things so from what i remember the chip was fundamentally useless because it barely worked in practice and the existence of the particle it was built on is still very dubious (aka we've got no proof it's actually a thing). read more here
Better to over-invest into quantum computers than under-invest into them.
Plus, technological development bears fruit on the timespan of decades.
field has promise but for the next few years it's not gonna have much use, can't wait for quantum cybersec to become a thing tho
quantum encryption? quantum communications?
that too, but classic cybersecurity is already neglected enough in the field, let alone this new and novel technology that nobody has any idea how to properly use yet.
I read something about them being able to crack encryption once they're powerful enough? This was years ago tho
still true but setting quantum computers up is a pain in the ass
Which is why there is a big focus on post-quantum cryptography so that by the point they're practical to use for that, nobody will be using quantum-computer-vulnerable algorithms.

if I heard about them right, the appeal of photonic ones is they're room temp
second point still stands, but damn they've made a room temp quantum computer? we might be making advances for once.
