Somebody asks me what the Harmonic Series has to do with Quantum Computing!

First of all you need to realize you've been brainwashed. The Perfect Fourth is not part of the overtone series. It's called the "Ghost Tonic" for that reason. In fact the Perfect Fifth is also a subharmonic as 2/3 or C to F. This means that if C is 1 and octave C is 2 and G is 3 as the Perfect Fifth then G=3=F at the same time which is actually "noncommutative phase" the secret of quantum nonlocality and quantum entanglement. Now maybe you don't believe me? Alain Connes, who got the Fields Medal in math, knows this secret. He states that music theory is a "universal scaling system" that unifies relativity and quantum physics because music theory is "noncommutative" with a "geometric dimension of zero." So the brainwashed music theorists will tell you that the infinite spiral of Perfect Fifths - which is the actual natural harmonics - is just a "modular" scale no different than an infinite spiral of natural thirds as 5/4 (instead of the logarithmic cube root of 2). Yeah but those musicologists don't understand noncommutative phase! Why? Because You all learn just as I did that the PErfect Fifth plus the Perfect Fourth = the Octave. But this is a lie from ARchytas! ARchtyas used the equation arithmetic mean x harmonic mean = geometric mean squared as the first logarithmic equation. Which is to say that the Perfect Fifth was the arithmetic mean and so HAD to be 3/2 and could not be 2/3 as C to F subharmonic. I have researched this since the mid-80s and I have books on it and a whole blog that gives the details. So if you read the research of that youtube vid - those professors - here is what their secret is:

"Reciprocity of fundamental frequency transmission coefficient (FFTC) is now investigated. Since the geometry is symmetric with respect to its center at f from A to B with two opposite values of v is equivalent to comparing FFTCs from A to B and B to A at f with a single value of v." 

This is exactly the secret of noncommutative phase. Just switch A to B with  2 to 3 and 3 to 2 with the same frequency centered at 1. In science it is called "time-frequency uncertainty" but in quantum physics it is called a "spinor" at spin 1/2 as time-frequency noncommutative phase. So that means that listening is nonlinear and so faster than time-frequency uncertainty - and so through meditation as listening based on noncommutative phase you can then "capture virtual photons" from the future! de Broglie figured this out as the Law of Phase Harmony - the superluminal velocity as quantum entanglement is from Frequency is to Time as Momentum is to Wavelength. It is relativistic quantum physics. So it enables macroquantum coherence at room temperature. This is the secret of nonwestern mantras as meditation.

To quote those same professors again:

"a single input frequency produces multiple harmonics in the output." 

and

"The antisymmetric elastic waves exhibit quantum-like behavior. " and "It is important to point out that the interpretation of the Dirac spinor is in terms of forward and backward propagating waves."

and 

"The superposition of elastic states... is therefore measurable without wave function collapse in contrast to what would be the case for the superposition of states of a true quantum system." 

and

"By considering media that mix different types of waves, the book addresses the interaction of sound with other physical and biological waves but also brings to light examples of extrinsic processes that can lead to symmetry breaking. The coherent conversion of sound into other types of waves as well as the sound-induced non-conventional topology of elastic, electronic, spin and biological waves are presented in the case of media exhibiting elasto-electronic, photo-elastic, magneto-elastic effects and biological mechano-transduction." 

and

"So we can avoid that drawback, by working with a quantum analog and our systems are acoustic quantum analogs of qubits. We call them Phi-Bits. So they exhibit the same capabilities of having superposition of states but they do not have the drawback of decoherence. They are stable. The Tech Foundation funds research that will not be funded by traditional federal sources, for instances, so we had to demonstrate that places like the National Science Foundation would not fund the research because it's too out there, out of the paradigm, it's too revolutionary for them to fund....we have three years of research, we have to demonstrates a set of phi-bits, to operate a well-known quantum algorithm...so have a tabletop system operating."
