Atul, welcome to the Beowulf list. My apology if you have posted here in the past. I invite you to make a post regarding quantum computing. This is a fascinating field in its own right.
Please start a thread - I will then make my comparison with guitars. On Tue, 20 Oct 2020 at 04:02, atul kumthekar <atul.b.kumthe...@gmail.com> wrote: > Regards Quantum, one area is security.
