Hi Prof P Singh!

I've heard that noise is an issue for quantum systems. While there are efforts to reduce noise or understand it, I've also heard of efforts to using the noise inherent in these systems (last I heard was by some Harvard researchers). In the end, which effort would be more plausible ?

Are you saying that there is an opportunity to launch QCoin based on post quantum/quantum-resitant cryptography ? :)

Another one for you. We all know that there are some implications for cryptography from breakthroughs in quantum computing. However, have there been any real instances of folks using quantum computing to decipher any encrypted information (encrypted using a sensible algorithm) ? If yes, while having an implication for privacy, would such capabilities have real world implications for cryptocurrency, if any ? Thanks for your time!

Why is making quantum computing hardware so .. err .. hard and why do pictures of quantum computers always look like they are cryogenic chambers ? I suppose it's because they need to operate at low temperatures but my question is why ?
