Posts Tagged ‘Schrödinger’s cat’

In one fable posted some years ago I had posited an idea that at infinitesimal spaces while treating the headache of Zeus the spark created by the fire god must behave in such ways that the clot and the spark act as one. In that thought experiment, Erwin Schrödinger’s cat achieves a similar state: Cat in a box would be exposed to a radioactive particle that had even odds of decaying or not. Until the box was opened, the poor cat would be both alive and dead at the same time, which seemed clearly absurd to Schrödinger.In other words these are entangled. Entanglement as a quantum effect describes where particles separated by vast distances mysteriously link up their states. Scientists in 2016 have already created with quantum-entangled bacteria.
Usually, we describe quantum physics as a set of rules that governs the behavior of extremely tiny things: light particles, atoms and so on to which realm of livings things and bacteria belongs to another order. This larger world, at the bacterial scale (which is also our scale — the chaotic realm of life) isn’t supposed to be anywhere near that weird.

There’s just something about the quantum world that doesn’t seem to make sense in ours. Bouts of migraine in most sufferers seem to be triggered by solar flares. The light takes some eight minutes to reach us but it triggers migraine earlier than that. Why?
But scientists don’t agree on where the boundary between the ordinary and the quantum world lies — or if it even exists at all. Chiara Marletto, a physicist at the University of Oxford and a co-author on the recent paper, which was published Oct. 10 in The Journal of Physics Communications, said that there’s no reason to expect that there’s a limit on the size of quantum effects.

“I’m interested in studying the border where quantum rules stop applying,” she told Live Science. “Some people say that quantum theory is not a universal theory, so it does not apply to any object in the universe, but actually will at some point break down. My interest is to show that actually, that’s not the case.”

In 2017, a team of researchers based at the University of Sheffield in England said they had created a state of what’s known as quantum coupling in photosynthetic bacteria. They placed a few hundred bacteria in a tiny, mirrored room and bounced light around. (Based on the length of the mini room, only a certain wavelength of light persisted over time, known as the resonant frequency.) Over time, six of the bacteria appeared to develop a limited quantum connection to the light. So the resonant frequency of light inside the tiny room seemed to synchronize with the frequency at which electrons jumped in and out of position inside the bacteria’s photosynthetic molecules.
Marletto said that her model shows that this effect likely involved more than just quantum coupling. There was likely something going on even weirder than what those experimentalists described, she said.

The bacteria, she and her colleagues showed, likely became entangled with the light. What this means is that the equations used to define each of the waveforms — of both the light and the bacteria — become one equation. Neither is solvable without the other. (According to quantum mechanics, all objects can be described as both particle and wave, but practically speaking, in “large” objects like bacteria, the waveforms are impossible to see or measure.)

Like Schrödinger’s proverbial cat in a box, the whole system seemed to exist in an uncertain netherworld. How often we have seen rational man interacting with rational men as we would assume every delegate, who deliberated around the table hammering out the Treaty of Versailles in 1919 and what did they produce? Just the opposite. Why speak of rational idea of man when he cannot fathom the weird world of justice and equality operating without? You deny justice with the most cogent arguments and quote instances out of the whole and what you produce is more misery and just opposite to your professed principles. This is entanglement on a moral plane. Between our physical universe and worlds created purely on abstract ideas only entanglement that is sustainable not by rules of men or by their material accomplishment but by moral laws. For me God is that moral being.
