Quantum computers are already here in a limited form, and fully functional versions are on the way. They will be as transformative for mankind as were the mainframe computers, personal computers, and smartphones that we all use. As do all advancing technologies, they will also create new nightmares. The most worrisome development will be in cryptography.
I'm writing to explain in basic terms how I was led to create what has come to be called the "many interacting worlds" theory of quantum mechanics, how it works, and what it might mean. I stress at the outset, though, that this new theory does not prove anything definitive about the true nature of quantum reality, at least not yet.
