This question already has an answer here:
How far are we from destroying classical encryption? Perhaps a more direct question, what will it take for my bitcoins to be in danger of a quantum brute force attack?
EDIT: I posted this question after reading a similar one, but felt that it was relevant since the other question is 2 years old now and DWave seems to have made new developments (major increases in qubit depth, new interests).
The comment below mentions that DWaves machines aren't crypto-breaking capable, and also that QC is only effective against asymetric encryption (the bitcoin kind!). I wonder if someone can expand on these points...
