There are two certainties over the next decade.. the sun will continue to rise, and nobody will be able to afford their own quantum computer in their own data centre.
I think AWS are banking on this with AWS Bracket, big time.
If you have watched 'The Social Dilemma' on Netflix then you'll know the big warning is that if all the mega huge life invader social networks out there can get you hooked on their algorithm on regular 'tradition compute' then wait till you see what happens when Quantum computing gets a hold of your ass.
I have read a fair amount about quantum computing, only because it appeared in AWS and it's interesting how it relates to biology and quantum mechanics, which got me curious.. oh and the fact that it totally looks like alien tech.
I can imagine all the other beneficial possibilities of AWS Bracket (which is the name for their Cloud-hosted quantum compute model), like super quick genome sequencing of future COVID viruses and variants (maybe it is doing that right now, who knows!)
And what comes after quantum? Well here is an extract from an interesting article from Nova PBS
“It looks likely that a single device, a quantum computer, would in the future be able to simulate all of quantum chemistry and atomic physics efficiently.”
So maybe Nature could allow more powerful kinds of quantum computers than the “usual” qubit-based kind? Strong evidence that the answer is “no” comes from work by Richard Feynman in the 1980s, and by Seth Lloyd and many others starting in the 1990s. They showed how to take a wide range of realistic quantum systems and simulate them using nothing but qubits. Thus, just as today’s scientists no longer need wind tunnels, astrolabes, and other analog computers to simulate classical physics, but instead represent airflow, planetary motions, or whatever else they want as zeroes and ones in their digital computers, so too it looks likely that a single device, a quantum computer, would in the future be able to simulate all of quantum chemistry and atomic physics efficiently.
The article concludes that quantum computers may not be able to simulate 'Quantum Gravity'. Phew... imagine that appearing in your AWS console?
