Cornell or Yale?

I have fortunately been accepted to both Cornell and Yale's applied physics PhD programs. They are my top contenders right now and I am trying to decide between the two. I will visit both schools. But at the moment, I would really appreciate your opinion on these two schools. My interest is in solid state/quantum devices.

Yale is extremely strong in quantum computing which is what interests me the most at the moment. Although this interest is very strong, it is almost a whim, a result of reading a few articles on a lazy summer day. I have done research in condensed matter but absolutely nothing related to anything close to solid state quantum computing. I don't know if I am justified in worrying that If I lost interest in quantum computing, Yale would not be able to provide me with as many good backup choices as Cornell would. On the other hand, Cornell has a strong presence in many areas that I am interested in, but not the area I am most interested in currently. Also I feel that New Haven might have a little more to offer than Ithaca in terms of social life?
