Yes this helps a great deal Ameno, thanks again for your very sound and vivid explanation. I sincerely appreciate the time and effort you spent writing your reply. Have a great day and thanks again for the help.

Right, I understand that saying the qubit contains an infinite amount of information prior to measurement is misleading and perhaps treading too far away from hard science which I certainly do not want to do. I am vaguely familiar (at least with the overall result) of the Holevo bound which...

I have a general question about extracting information from measurement of a qubit. Theoretically a qubit in a superposition state contains an infinite amount of information, but when measured collapses to a definite state and result. My question is this: Is there a way to obtain a value from...

I was curious if it would be possible to construct an incredibly simple and most likely trivial computer based on an interferometer style setup which could generate random numbers based on the quantum mechanical nature of light. Namely, with a basic laser pointer, some mirrors, and a beam...

Also, as a follow-up to this question, I think David Deutsch touches on this topic in the first 2 videos of his lecture series by http://www.hpl.hp.com/breweb/quiprocone/Protected/DD_lectures.htm" . Really good set of lectures by the way if any of you were interested. Not sure if this helps a...

Thanks again for the response cortiver, very much appreciated. So just for clarification, depending on the axis the Stern-Gerlach apparatus is measuring in, results in a differently constructed circuit? So for the z-direction it is simply the measurement operation, the +x and -x require a...

I have a general question about the Stern-Gerlach experiment. When a spin 1/2-particle passes through the magnets, is that effectively equivalent to applying a Hadamard transform to the state of the particle going through the apparatus? Also, let's say I wanted to create a quantum circuit...

Hey all, Just like to prefix this question with the statement that I am a computer scientist with a strong interest and passion for physics, so please forgive me if this question is a tad naive. With that out of the way, I have a general question about this image: It's from "The Little...

Thanks a lot for the help arkajad. I will certainly give your approach a shot. Thanks again.

To map from some point on the sphere denoted by spherical coordinations (theta_1, phi_1) to (theta_2, ph_2). where instead of the full range: 0 <= theta <= 180 0 <= phi <= 360 the ranges are limited by some theta_1, theta_2, phi_1, and phi_2: theta_1 <= theta <= theta_2 phi_1...

Hey guys, I'm attempting to map some discrete points on the surface of the Bloch sphere: For instance, the full spectrum of ranges for variable theta is 0 < theta < pi. However, my goal is to limit that range from some theta_1 < theta < theta_2. I was going to use a spherical harmonic...
