Resolving Quantum Superpositions

If I have understood this correctly when a photon pair is created as a quantum superposition the moment the quantum states of one photon are measured and hence known, so by a kind of “subtraction” or “division” are that of the other. This happens “faster than the speed of light”. It does not matter what the distance is. Measuring one “resolves” the other. There is an implication of time in this. It depends which equations you use.

To the classical “reality” based physicist it is spooky though very groovy.

“There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.”

Science is inherently conservative…and time and time again that “certainty” is found to be unwarranted. New stuff happens…

History shows that the adamant insistence of some scientists has been blinkered and nigh on fanatical. History repeats itself this is a historical fact.

Human beings have created the notion of quantum superposition in the first place, through the mathematical descriptions, of observable phenomena.

The photons do not know what humans have described them as. Nor can they solve the equations applied. They are just photons. They do not have big brains.

Is the quantum superposition real or an artifact of human mind unable to adequately {for now} model and understand what is happening?

It works…

Was there no superposition in the first place only a love of human complexity?

Humans don’t like likelihood or probability. They like to assert, insist and be adamant. {soapbox}

When they do this, they are probably inaccurate and “wrong”.

How can we resolve this tendency?

Quantum Means Confinement

Non-scientists can bandy the word quantum about and use it as a marketing tool. In the sense of electrons, atoms, molecules and nanoparticles many quantum phenomena arise out of tight spatial confinement and with an electromagnetic potential.

Transition between states requires a quantum of energy. That means a bit, an amount, of energy and the amount of energy is very precise. If it does not exactly match the gap in the energy “ladder” there is no transition. Try climbing a physical plane ladder without using the steps, it is tricky.

I think of some quantum phenomenon as a special case of very precise resonance.

People can get all excited by wave particle duality, man.

They can extrapolate beyond appropriateness. I have seen the phrase quantum allowing on a number of web sites. The weird thing is quantum mechanics forbids more than it allows.

It is strange people like groovy words…

Oh well…

Are You Quantized by Socio-political Norms?

Are you a being in a box, trapped by the confines of socio-political norms?

Do you have to subscribe to the allowed eigen-values of society?

Must you only speak the allowed eigen-truths?

Under the cosh of the woke operator must you only emit certain sonic vibrations, whose wavefunction is confined by political correctness?

Do you find yourself noncommutative and orthogonal with the herd / shoal?

Are you a real or imaginary being?

I am sorry I have to go now; the thought police are in the driveway and I must flee…

Quantum Fluctuations {AUM?}

This from Wikipedia

In quantum physics, a quantum fluctuation (also known as a vacuum state fluctuation or vacuum fluctuation) is the temporary random change in the amount of energy in a point in space, as prescribed by Werner Heisenberg’s uncertainty principle. They are minute random fluctuations in the values of the fields which represent elementary particles, such as electric and magnetic fields which represent the electromagnetic force carried by photons, W and Z fields which carry the weak force, and gluon fields which carry the strong force. Vacuum fluctuations appear as virtual particles, which are always created in particle-antiparticle pairs. Since they are created spontaneously without a source of energy, vacuum fluctuations and virtual particles are said to violate the conservation of energy. This is theoretically allowable because the particles annihilate each other within a time limit determined by the uncertainty principle so they are not directly observable. The uncertainty principle states the uncertainty in energy and time can be related by Δ E Δ t ≥ 1/2 ℏ   where 1/2ħ ≈ 5.27286×10−35 Js.

This means that pairs of virtual particles with energy Δ E and lifetime shorter than Δ t are continually created and annihilated in empty space. Although the particles are not directly detectable, the cumulative effects of these particles are measurable. For example, without quantum fluctuations, the “bare” mass and charge of elementary particles would be infinite; from renormalization theory the shielding effect of the cloud of virtual particles is responsible for the finite mass and charge of elementary particles. Another consequence is the Casimir effect. One of the first observations which was evidence for vacuum fluctuations was the Lamb shift in hydrogen. In July 2020, scientists reported that quantum vacuum fluctuations can influence the motion of macroscopic, human-scale objects by measuring correlations below the standard quantum limit between the position/momentum uncertainty of the mirrors of LIGO and the photon number/phase uncertainty of light that they reflect.

Dai-Ichi Hotel Dream 07-08-22

This dream is in stark contrast to the one yesterday morning. Although I am reading “Le bureau des jardins et des étangs”, by Didier Decoin which is set ~800 years ago I am not getting much other Japanese influence.

The dream opens with the view of a large boardroom table around which are sat men in suits, mostly grey but some dark navy. They are all over 40 years of age, some have grey hair, some are partially balding. They are of mixed nationality with some being oriental. Everyone is wearing a tie. At the end of the table there is a large white presentation screen. I am in front of it with a pointer stick and am giving a technical and commercial presentation to the audience, who are listening intently. I am dressed in a charcoal grey suit with a navy blue tie and am wearing my rimless spectacles.

The presentation finishes and I am outside the boardroom in the lobby of a hotel. An American man in a grey suit with a patterned darker grey inlay motif comes up to me and says, “Thanks for that Alan, it was very useful. But you let it go a bit at the end, didn’t you?”

“Yes, I did, I did that on purpose.”

The American man walks with me to the hotel reception desk. I tell the clerk that I am going out for a wander. He gives me a card with the name of the hotel and a telephone number. The hotel is called The Dai-Ichi Hotel” and the name is written in Kanji and Latin script. He says, “if you get lost hail a cab and show them this”.

The hotel is in a very built up area of Tokyo and within walking distance of the central station. I take my time and enjoy wandering around.

It is starting to get dark, and the lights come on. I look at the card to remember the name of the hotel “Dai-Ichi”. I know dai-ichi means number one, first or top.  I turn the corner and there is the high rise Dai-Ichi hotel.

I enter the lobby and sit down. Next to me there are some young Japanese people. One of them is a young hostess and she has been sent there for me. She is very friendly, and I know that she is by way of a business temptation for me. I say, “no thank you I am tired” and go up to my room. In the dream I know that there are some low level attempts at corruption going on pertaining to the content of my talk.

In the dream I make sure that I remember Dai-Ichi which verbally would be Dai-Ich with the last I silent.

I wake up and the first thing I do after putting the kettle on is type Dai-Ichi Hotel Tokyo into Google.

It looks like this:

And is in a quarter not too far from the Imperial Palace. It also not too far from my favourite hotel, Hotel New Otani. I have not been to Tokyo for ~two decades. Back in that “lifetime” I was good at doing technical / commercial presentations. After going to “Semicon East” I met representatives of Canon and Nikon in the lobby of the New Otani. It was considered a good neutral place for the first meetings.

I have never heard of the Dai-Ichi Hotel before.

When I used to go to Tokyo, it was great to get off the plane and into a hotel room, shower, dress in a yukata, and then order a couple of bottles of Asahi beer and a bento box. Many gaijin who suffer jet lag wander the streets of Tokyo at strange hours of the day. I often met them.

Not Being Thorough and Ray Two

I need a bit of break now because me swede is mashed. I have been doing another trawl trough the patent documents cited as contra-indications for my application. They pointed me to things like this Nature Review article.

It looks like one of the applications was very heavily stimulated by this article and I am not sure how they manged to get grant. Some of the embodiments seem a tad cut and paste. When I was trawling the quantum optics patents a while back, I kept getting this feeling, this question, “how come they got that past the examiner?”

I wrote about a molecular exciton in my Ph.D. theses. The two chromophores were coupled by strong hydrogen bonding. Guess what? I started thinking about molecular excitons coupled to a resonant cavity. Physicists are not so keen on molecules.

I am pretty sure that the examination was a first pass only one, because if the examiner had drilled down into the detail, he would have seen that the two contra-indications are concerning very different phenomena. But I do accept his argument that a couple of dependent claims might be obvious. After all, me with my rusty brain, saw them.

There is this thing that many people skim and conclude. They jump to conclusions at haste without looking at ALL the evidence. There are a lot of people in the world who are not thorough. They think that have understood but they have not checked their understanding. People do not check, they assume..

Surface skimming or fathoming the depths?

I guess I have the second ray approach…

I have been burrowing like a mole and storing my nuts. Tomorrow after I have left things to my background intuitional processors, I’ll draft my reply.

It is 33˚C in the shade outside and will probably go one degree more.

That is a toasty…

The Direction of Ray II

    “The Scholar knows the truth. All is revealed to him. Surrounded by his books, and sheltered in the world of thought, he burrows like a mole, and finds his way into the darkness; he arrives at knowledge of the world of natural things. His eye is closed. His eyes are opened wide. He dwells within his world in deep content.

    Detail on detail enter into the content of his world of thought. He stores the nuggets of the knowledge of the world, as a squirrel stores its nuts. The storehouse now is adequately full… Sudden a spade descends, for the thinker tends the garden of his thought, and thus destroys the passages of mind. Ruin arrives, destroying fast the storehouse of the mind, the safe security, the darkness and the warmth of a satisfied enquiry. All is removed. The light of summer enters in and the darkened crannies of the mind see light… Naught is left but light, and that cannot be used. The eyes are blinded and the one eye seeth not as yet…

    Slowly the eye of wisdom must be opened. Slowly the love of that which is the true, the beautiful and good must enter the dark passages of worldly thought. Slowly the torch of light, the fire of right must burn the garnered treasures of the past, yet show their basic usefulness…

    The seven ways of light must wean away the attention of the Scholar from all that has been found and stored and used. This he repulses and finds his way into that Hall of Wisdom which is built upon a hill, and not deep under ground. Only the opened eye can find this way.”

Ray Two

  ” ‘Again I stand; a point within a circle and yet myself.’ The love of love must dominate, not love of being loved. The power to draw unto oneself must dominate, but into the worlds of form that power must some day fail to penetrate. This is the first step towards a deeper search.

   The word goes forth from soul to form: ‘Release thyself from all that stands around, for it has naught for thee, so look to me. I am the One who builds, sustains and draws thee on and up. Look unto me with eyes of love, and seek the path which leads from the outer circle to the point.

    I, at the point, sustain. I, at the point, attract. I, at the point, direct and choose and dominate. I, at the point, love all, drawing them to the center and moving forward with the travelling points towards that great Center where the One Point stands.’ What mean you by that Word? “
