with The 50-bit quantum computer you have ~2^49 computing power per second.
this should be similar 14077497671065 seconds of work for 7700.
still this expect full usage of quantum computing power and no problems with input output algoritms etc.
we don't have YET any serious algorithm that can use that power. Problems solved are syntetic mostly to see how much we CAN do etc.https://www.pcworld.com/article/3176853/hardware/ibms-new-q-program-to-include-a-50-qubit-quantum-computer.html
