Quantum Computing: Top Players 2021

Check out the physics courses that I mentioned (many of which are free!) and support this channel by going to where you can create your Brilliant account. The first 200 will get 20% off the annual premium subscription. In this video I give you an overview on the different technologies for quantum computing, their benefits and disadvantages, who is working on what, and how far along they are. Correction to what I say at 7 mins 17 seconds: They have of course a net POSITIVE charge. Correction to what I say at 9 mins 24 seconds: D-wave informed us that 5600 qubits is a bit too high. 5000 would be the most accurate number. Many thanks to Tanuj Kumar for help with this video.
