Possible quantum computer limits

A discussion of possible limitations on the power of quantum and classical computers It is a useful discussion of NP hard problems. My reaction to it is that even if his conjecture that we cannot globally solve NP hard problems is correct there is still commercial viability in improving and expanding the cases where we …

Are quantum computers needed for AGI ?

Dwave systems, CTO Geordie Rose, theorizes about the usefulness and possible necessity of quantum computers for human level and higher artificial intelligence Summarizing: Are humans somehow getting good approximate solutions to problems that are NP hard ? If so, would quantum computers be useful to develop alternative ways to get as good or better than …
