Does the Quantum Financial System disregard Blockchain or do they work in tandem?

I'm sure someone out there can help us further explain. Some of the things being posted here are sort of confusing, seeming to indicate that once QFS is refined and established, that Blockchain itself will no longer be needed.

Is this really the case?

Quantum Blockchain

>Blockchain has been around for some time now but arguably, has never really fulfilled its potential as the next great banking innovation. According to Deltec Bank, Bahamas- “A combination of quantum computing and blockchain technology could change things as transactions can be even more secure and faster with increased encryption.” It also means that the computing power is there to remove any latency and power issues that exist within blockchain technologies.

The above seems to suggest that the two technologies will be used in tandem to innovate the banking sector.

Can anyone more aware of all of the factors please weigh in?
