Quantum is getting hot in 2019, and even <Ciro Santilli> got a bit excited: <quantum computing could be the next big thing>.
No useful algorithm has been economically accelerated by quantum yet as of 2019, only <quantum supremacy>[useless ones], but <quantum computing player>[the bets are on, big time].
To get a feeling of this, just have a look at the insane number of startups that are already developing <quantum algorithms> for hardware that doesn't/barely exists! https://quantumcomputingreport.com/players/privatestartup (https://web.archive.org/web/20191223175204/https://quantumcomputingreport.com/players/privatestartup/[archive]). Some feared we might be in a bubble: <Are we in a quantum computing bubble?>
To get a basic idea of what programming a quantum computer looks like start by reading: <quantum computing is just matrix multiplication>{full}.
Some people <quantum computing skepticism>[have their doubts], and that is not unreasonable, it might truly not work out. We could be on the verge of an <AI winter> of quantum computing. But <Ciro Santilli> feels that it is genuinely impossible to tell as of 2020 if something will work out or not. We really just have to try it out and see. There must have been skeptics before every single <next big thing>.
