quantum computing seems to be a growing bubble? One has not been able to unify QM with QG. I suspect many of the assumed and also so called tested wonders of QM will break down when one finally are able to unify with QG or simply test at much much much shorter time intervals. Still perhaps a good investment to invest in quantum computing, buy into a growing bubble and get out in time. ?
It's always come across as a solution looking for a problem. Most of the money is buried in research. I know IBM and Google have Quantum deployments but I've no idea who's using them and for what. I vaguely remember reading about quantum circuits being used in bond market prediction but I've no idea how that is done or panned out.
At tech conferences I kept hearing how QC was going to be "the next big thing", still yet to happen in my lunchtime.
