But basically the gist was as follows: quantum computers are faster than classical computers and the question is why? Where does the computation speedup takes place? In the many parallel worlds is the answer. Think of a quantum computer as many classical computers working in parallel in each if the many worlds of MWI, and then combining the computation results.<br /><br />But as it was demonstrated experimentally, quantum computers are nothing but analog computers (vs. digital) and you get massive parallelism from the continuous analog structure regardless if it is a qbit or a pure classical wave and not from hypothetical many worlds. <br /><br />Breaking RSA comes down on how fast you can do a Fourier transform. I am not sure if it was actually done using classical waves, but if someone succeeded it will be a well guarded secret: all modern commercial transactions are based on RSA.

"Supporters of the Many Worlds Int...Hi Florin,<br />"Supporters of the Many Worlds Interpretation like David Deutsch contend it is quantum mechanics"<br />This would be a strange claim. You can use QM all your life without believing in any interpretation.Quantum calculation procedures do not require any interpretation.So I am surprised that one has to use any interpretation to decide whether the speedup is due to QM or not.kashyap vasavadahttps://www.blogger.com/profile/10732897306667764590noreply@blogger.com
