Over a few weeks, I came to comprehend that the sound of one hand clapping is an illusion. The hand’s movement mimics clapping, but the only way to make the illusion a reality is to add a second hand. The sound of one hand clapping can be imagined, but the clap doesn’t exist until another hand is present. With that realization, I recognized the koan’s question as a way to understand the Buddhist doctrine of emptiness (śūnyavāda in Sanskrit), which says that no individual thing or person has any intrinsic existence, but exists only relationally, dependent on everything else. The concept of an individual nature is, like one hand clapping, an illusion.
How does this speak to (or not) the idea of coherence in quantum mechanics?

summary - Frederico Faggin is a physicist and microelectronic engineer who was the developer of the world's first microprocessor at Intel, the Intel 4004 CPU. - Now he focuses his attention on developing a robust and testable theory of consciousness based on quantum information theory. - What sets Frederico apart from other scientists who are studying consciousness is a series of profound personal 'awakening'-type experiences in which has led to a psychological dissolution of the sense of self bounded by his physical body - This profound experience led him to claim with unshakable certainty that our individual consciousness is far greater than our normal mundane experience of it - Having a science and engineering background, Faggin has set out to validate his experiences with a new scientific theory of Consciousness, Information and Physicality (CIP) and Operational Probabilistic Theory (OPT)

One of the problems in approaching quantum gravity is the choice for how to best represent it mathematically. Most of quantum mechanics is algebraic in nature but gravity has a geometry component which is important. (restatement)
This is similar to the early 20th century problem of how to best represent quantum mechanics: as differential equations or using group theory/Lie algebras?
This prompts the question: what other potential representations might also work?
Could it be better understood/represented using Algebraic geometry or algebraic topology as perspectives?

Instead of trying to resolve in general this problem of how macroscopic clas-sical physics behavior emerges in a measurement process, one can adopt thefollowing two principles as providing a phenomenological description of whatwill happen, and these allow one to make precise statistical predictions usingquantum theory
To resolve the measurement problem from quantum mechanics into the classical realm, one can use the observables principle and the Born rule.
-
Principle (The Born rule). Given an observable O and two unit-norm states|ψ1〉 and |ψ2〉 that are eigenvectors of O with distinct eigenvalues λ1 and λ2O|ψ1〉 = λ1|ψ1〉, O|ψ2〉 = λ2|ψ2〉the complex linear combination statec1|ψ1〉 + c2|ψ2〉will not have a well-defined value for the observable O. If one attempts tomeasure this observable, one will get either λ1 or λ2, with probabilities|c21||c21| + |c22|and |c22||c21| + |c22|respectively.
-
Principle (Observables). States for which the value of an observable can becharacterized by a well-defined number are the states that are eigenvectors forthe corresponding self-adjoint operator. The value of the observable in such astate will be a real number, the eigenvalue of the operator.
What does he mean precisely by "principle"?
-
Axiom (Dynamics). There is a distinguished quantum observable, the Hamil-tonian H. Time evolution of states |ψ(t)〉 ∈ H is given by the Schr ̈odingerequationi~ ddt |ψ(t)〉 = H|ψ(t)〉 (1.1)
-
Axiom (States). The state of a quantum mechanical system is given by a non-zero vector in a complex vector space H with Hermitian inner product 〈·, ·〉.
-
Axiom (Quantum observables). The observables of a quantum mechanical sys-tem are given by self-adjoint linear operators on H.

TLDR Hyperion is a moon orbiting Saturn and has chaotic motion about its CoM. This chaos is modeled correctly with classical mechanics but incorrectly with quantum mechanics. The catch being that if the average of all wavefunction collapses due to decoherence with interactions particles+photons is included then the prediction is correct. However, averaging is a non-physical process and, furthermore, collapsing a wavefunction requires instantaneous transfer of information which is nonphysical.
- Saturn's moon, Hyperion, has chaotic motion due to the orientation of the moon about the orbit. Due to chaos, we can't predict orientation due to chaotic tumbling.
- This can be described classicly with relativity.
- Quantum Mechancis has been falsified because it fails to recreate or predict chaotic behaviors of the moon after 20 years.
- Due to the linear nature of the eigenvector in Schrodinger's equation, it can not contain chaos.
- By applying the correspondence principle, we only see chaos for up to the Ehrenfest time upon having the time function applied.
- Physicists explain this incongruence in theories because the Schrodinger equation isn't including the entangled interactions of light/dust. These effects result in decoherence.
- By averaging over the predictions we achieve the same solution as classical mechanics. Howevering averaging isn't a physical process. (e.g. rolling a 6 sided dice many times gives an average of 3.5 which is nonphysical)
For a model to be real, we require that each individual prediction is true not the average. One solution is that Hyperion interacts and is having it's wavefunction updated nonlinearly resulting in decoherence. * Collapse of a wavefunction is said to not be physical due to instantaneous transfer of information being impossible. However, this wavefunction collapse due to interactions is required for the chaos of Hyperion to be modeled correctly. This is the issue.

“Because physicists started out with the imaginary, unstable cube as their model instead of the real-world stable tetrahedron, they got into all these imaginary numbers and other complicated and completely unnecessary mathematics. It would be so much simpler if they started out with the tetrahedron, which is nature’s best structure, the simplest structural system in Universe.
(Just as an aside, to remember later when you’re studying physics in school, I want to point out that the tetrahedron is also equivalent to the quantum unit of physics, and to the electron.)”

His questioning of the scientific orthodoxy was the expression of a rare and maverick intelligence.

Las graficas de la energía de confinamiento en su estado fundamental en contra del tamaño (radio) por nanopartículas de sulfato de zinc en la Figura 14 muestran la dependencia de confinamiento en el tamaño de los puntos quánticos. El resultado muestra que el estado fundamental de energía en confinamiento es inversamente proporciona al tamaño (radio). Por lo tanto, cuando uno incrementa su radio (tamaño) la energía de confinamiento decrece pero nunca llega a cero. Eso es, el energía mas baja posible para el punto quántica de muestra no es cero. El confinamiento comienza cuando el radio del punto cuántico de muestra es comparable o del orden del radio exciton de Bohr.

The notion that counting more shapes in the sky will reveal more details of the Big Bang is implied in a central principle of quantum physics known as “unitarity.” Unitarity dictates that the probabilities of all possible quantum states of the universe must add up to one, now and forever; thus, information, which is stored in quantum states, can never be lost — only scrambled. This means that all information about the birth of the cosmos remains encoded in its present state, and the more precisely cosmologists know the latter, the more they can learn about the former.

A quantum blockchain, the pair suggests, would take advantage of entanglement, which in most cases, applies to situations regarding space. But it could also be useful for situations involving time, such as blockchains. In such a blockchain, the pair explains, transaction records could be represented by pairs of entangled photons linked in chronological order. When transfers take place, photons would be created and absorbed by the hubs that comprise a network. But since entangled photons are linked across time, they can be caused to have never existed at the same time.

=(α∣0⟩+β∣1⟩)(γ∣0⟩+δ∣1⟩)=αγ∣00⟩+αδ∣01⟩+βγ∣10⟩+βδ∣11⟩.
Might be the answer to an above inquiry.

we apply a Hadamard gate
What is the method to evaluate whether the output of a Hadamard gate should invert the bottom qubit or not?
is (0 + 1) / sqrt 2 high or low?
I'm missing something fundamental here.

equal
Frustrating wording here for me... Why is the word "equal" here at all. Doesn't seem to clarify anything.

quantum teleportation
I was thinking yesterday that "quantum" anything is both much more exciting and much less exciting than we've been led to believe by "Pop Science".
It seems to boil down so far to some fancy linear algebra. I'm sure time will prove me a fool for thinking this, but just want to jot my thoughts down here.

For Computer Scientists, Microsoft put together a primer to Quantum Computing for us here: https://www.youtube.com/watch?v=F_Riqjdh2oM
I could understand some of it (through 40m), but think this series of articles will help immensely and I'll return to it after.

What does it mean for a matrix UUU to be unitary? It’s easiest to answer this question algebraically, where it simply means that U†U=IU^\dagger U = IU†U=I, that is, the adjoint of UUU, denoted U†U^\daggerU†, times UUU, is equal to the identity matrix. That adjoint is, recall, the complex transpose of UUU:
Starting to get a little bit more into linear algebra / complex numbers. I'd like to see this happen more gradually as I haven't used any of this since college.

unitary operator is a surjective bounded operator
Why must unitary operator only be surjective? Why not bijective?

Special Complexity Zoo Exhibit: Classes of Quantum States and Probability Distributions 24 classes and counting! A whole new phylum of the Complexity kingdom has recently been identified. This phylum consists of classes, not of problems or languages, but of quantum states and probability distributions. Well, actually, infinite families of states and distributions, one for each number of bits n. Admittedly, computer scientists have been talking about the complexity of sampling from probability distributions for years, but they haven't tended to organize those distributions into classes designated by inscrutable sequences of capital letters. This needs to change.

The new experiment shows that, in a quantum world, two people can end up disagreeing about a seemingly irrefutable result, such as the outcome of a coin toss, suggesting something is amiss with the assumptions we make about quantum reality.

Frauchiger and Renner came up with their thought experiment, which is an extension of something the physicist Eugene Wigner first dreamed up in the 1960s.

Hegel believed that history culminated in an absolute moment - a moment in which a final, rational form of society and state became victorious.
and probably not a bad outcome in an earlier era that thought of things in terms of clockwork and lacked the ideas of quantum theory and its attendant uncertainties.

“We often discussed his notions on objective reality. I recall that during one walk Einstein suddenly stopped, turned to me and asked whether I really believed that the moon exists only when I look at it.”

this week’s announcement by Google that a machine made by a Canadian company, D-Wave Systems, which is marketed as “the world’s first commercial quantum computer”, had shown spectacular speed gains over conventional computers. “For a specific, carefully crafted proof-of-concept problem,” Google’s Hartmut Neven reported, “we achieved a 100-million-fold speed-up.”

the strongest evidence yet to support the most fundamental claims of the theory of quantum mechanics about the existence of an odd world formed by a fabric of subatomic particles, where matter does not take form until it is observed and time runs backward as well as forward.

The mathematics of almost all eigenvalue problems encountered in wave physics is essentially the same, but the richest source of such problems is quantum mechanics, where the eigenvalues are the energies of stationary states ("levels"), rather than frequencies as in acoustics or optics, and the operator is the hamiltonian.
