This is an excellent video, probably the best TL;DR on all things quantum computing I have ever seen (the first 1/4 of the video), making clear the limitations.

This is an excellent video, probably the best TL;DR on all things quantum computing I have ever seen (the first 1/4 of the video), making clear the limitations. A great example of what all science comms should be like. some choice quotes: > quantum initiatives differ somewhat from nation to nation but they usually contain research programs on four key topics: - (1) quantum computing - (2) the quantum internet - (3) quantum metrology - (4) and quantum simulations ## (1) Quantum computing > quantum computing quantum computing is one of the most interesting developments in the foundations of physics right now. > [...] this speed up only works for certain types of calculations, so quantum computers are special purpose machines [...] > the problem with quantum computers is that for them to become commercially useful you need to be able to bring a large number of qubits into controllable quantum states and that's really really difficult [...] > estimates say the number we need to reach is roughly a million qubits [...] status of research is presently at about 50 qubits > [...] the major question for quantum computing is not does it work; the question is will it scale.
