Following on this issue through GitHub, it seems the problem is related to the tornado server that jupyter uses.
For those that can't wait for an official fix, I was able to get it working by editing the file tornado/platform/asyncio.py, by adding:

import sys

if sys.platform == 'win32':
    asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
