Where did you get the statement (e.g. in your Step One) that tilting one detector so as to reach 25% errors occurs at 30 degrees?

The situation you pose can be simplified, in which case the answer is more obvious: The two travelers need not be twins, and they need not travels in opposite directions. In fact invoking "twins" and the idea of motion in "opposite directions" confuses the issue with irrelevant information...

I also find that this way of thinking about QM makes sense: "Anything that can happen does happen," but each possible happening has a probability associated with it. The best that QM math can do is provide that probability. I can then say that a manifestation of quantum "weirdness" is something...

I like a simplistic approach to "weirdness" in quantum mechanics, particularly when teaching amateur scientists. The big three weirdnesses are (1) the uncertainty principle, (2) wave-particle duality, and (3) entanglement. 1: Everything in the universe, notably subatomic particles, and always...

Much of the confusion and mystery surrounding wave-particle duality can be resolved by the following terse statement (e.g. by John Polinghorne): The waves in wave-particle duality are waves of probability. Thus in a two-slit experiment, especially if done gradually one photon at a time...

I sense that you might want to start with a very simplistic approach to grasping the general concept of a spinor. Consider how you might mathematically describe physical things that vary in complexity. First, what can be a mathematical description of something quite simple, the current...

One way to approach this topic is to consider one or more specific controversial ideas or concepts inherent in quantum mechanics. I recently published a short non-technical (less-then-60-page) booklet where I show why concepts such as the uncertainty principle, wave-particle duality, and...

I use c "equal to 1" for convenience when I want to calculate a time in "how many YEARS," and/or I want to calculate a distance in "how many LIGHT YEARS." Remember that when c is set equal to 1, it means that c is a measure of speed wherein c = 1 lightyear/year. Of course: by definition a...

Think of how the speed of sound is abbreviated: Mach 1, etc.

If you seek a discussion of the principle of stationary action that starts with simple math, proceeds in small steps, then shows its application to general relativity, and ends with its relation to Feynman's path integral quantum mechanics, please consider my book, available at Amazon...

I wrote a book on relativity (both special and general, plus section on quantum mechanics) specifically for someone who knows little math but is interested in the math and logic of relativity. My premise is that even if you know only high school math (had good courses in algebra, trig, geometry...

Thanks! I can go on from here. Much appreciated, Lou

Hello, The source is http://quantumfrontiers.com/2012/09/17/how-to-build-a-teleportation-machine-teleportation-protocol/ The pertinent quote in the text is "..., Alice rotated her apparatus to align with the Bell basis, and by doing so, the entangled state of her qubits was transformed to...

Most protocols on Quantum Teleportation (using Alice and Bob as performers) include a crucial step where Alice performs a Bell State Measurement. Usually the applicable math is given in the protocol, but many protocols make the following kind of statement with no explanation: "Alice must...

Everything's OK till your last sentence, "And that is ruled out by the Bell inequality." You should say, "And that (the existence of hidden variables) is ruled out by a violation of the Bell inequality." If you are convinced that your evidence for the violation is valid --presumably in a...
