Those are cps. (Cycles per second)
But here, the article says the particles are two photons of light and the two are connected via fiber-optic cable which is a medium of light. So where is the separation needed to prove that entanglement is happening? I don't see any separation here.
However, if one photon was sent over one fiber-optic cable onto another fiber-optic cable and the two cables were disconnected, then I would say we had a valid test. But I don't see how they separated them from the original medium, the one fiber-optic cable?
Or am I missing something here?
1. The crazy thing is, qubits can also achieve a mixed state, called a “superposition” where they are both 1 and 0 at the same time.
Like Schroedinger’s cat? (sp).
I thought of the cat when I read the article.
I just read an article that explained quantum computers like this:
The way a regular computer finds an answer is akin to testing mazes one at a time until it finds the right one.
Quantum computers will test all of the mazes at once.
I don’t pretend to understand how the hell the whole mixed state thing works :)
but as a layman, I don’t have to. I just think it’s really cool to read about even if I only grasp about 2 percent :)
Just how the natural laws of physics accomplish the virtually instant transmission and putting into effect of a change in quantum state in entangled particles is unknown and a great mystery for physicists. It makes no more intuitive sense than would wiggling the big toe on your left foot and discovering that doing so makes Nancy Pelosi tilt her head upward and cackle like a deranged hen.
Einstein, who predicted quantum entanglement, was vexed by his discovery and famously described it as "spooky action at a distance." The immediate benefit of the new experimental demonstration of quantum entanglement is that it offers physicists a new tool for exploring the phenomenon.
As for Star Trek, the transporter was conceived and used by Gene Roddenberry as a way to prevent the show from slowing down or having odd transitions whenever characters and action had to move off the Enterprise. The transporter is like Samantha on Bewitched twitching her nose to use magic. As with Star Trek's transporter, the witches' nose twitch helps to speed the story along.
In neither instance though are transporters or witchcraft real. Trying to analyze them as potentially real is fundamentally a literary exercise and not an analysis based on physics.
I sincerely appreciate your feedback.
HOW does that happen?? I will almost be sad when they find out but there is always a new mystery to solve :)
As for “quantum state”, I am lost.
I found a definition as follows...
A quantum state is any possible state in which a quantum mechanical system can be...
Can you put that in simpler words?
Because it sounds like science fiction the way it’s written.
thank you
Quantum computing is really a mathematical reality awaiting the discovery of a theoretical physical medium.
What I mean by “physical medium” is the silicone chips. Their discovery allowed the high speed binary computing we have today because of a natural property silicone has: it has a crystalline grid structure on a microscopic level which allows it to be assigned with millions of finite addresses whose electrons can be switched on and off.
The crystalline address structure is so regular and fixed that huge amounts of on/off values (binary data) can be stored and accessed repeatedly with predictable results. It is the microscopic scale of these grids that allows the high speed processing we have today.
To make it any faster, you would either need a structure that is smaller, or a higher order than binary.
Binary computing (on/off) is a mathematical limitation. Quantum computing is simply mathematics not limited to binary. Theoretically, there is no reason math should be limited to binary - a base 2 system is slow and cumbersome compared to a base 3, base 4, etc.
The only thing limiting us to base 2 computing is the properties of silicone which only allow the addresses to have two states; “on” or “off”.
As soon as some microscopic crystalline structure is discovered or synthesized whose addresses can be switched to more states than “on” or “off”, we will have quantum computing.
The math is already there. We are just waiting for a physical medium that can store data beyond the limitations of binary.
If you can think of something that will do that, then you will be rich and famous.
I’m going to try Parmesan cheese - wish me luck.
lol
Besides for some of you on this board, it is a STAGGERING thing to understand.
I appreciate your post.
I get a little more insight with each one if even understand ONE thing out of 20 in a post.
And that’s my average lol
I don’t get what else there is between on/off.
I don’t get quantum state. Something is what it is or it isn’t!! :(
I can’t be awake and asleep at the same time!!
Can’t be here and in England at the same time.
Can’t be fat and skinny at the same time. Just fat for now lol
I think I need a Xanax.
It sounds like almost but not quite digital vs. analog. Not quite that, something more.
this isn’t matter teleportation. more like instantanious information transfer over unlimited distances
obviously, a huge deal for military and space comms
A silicone is a polymer made up of siloxane (−R2Si−O−SiR2−, where R = organic group). Silicones are typically colorless, oils or rubber-like substances.
You mean the chemical element silicon.
Regards,
A physical medium, eh? Would it have to be in a solid state?
This insight further explained the collective energy spectra of stars as being generated by elements in the star with different individual emission spectra. Stars heated atoms of different elements to thousands of degrees, which then cooled as they reached the star's surface and emitted excess heat energy as light in quantatized photons of specific frequencies corresponding to the atomic structure of the element.
Recall how every atom of every element is composed of protons and neutrons in a nucleus, with electrons orbiting it. When energy is added in the form of heat, the electrons jump to higher orbits, but then take the first opportunity offered by cooling to shed that energy in quanta corresponding to the fall of electrons into a lower orbit.
Or, to it another way, in moving from an excited hot state of excess energy to a cooler relaxed state, the atoms of an element reveal their nature as quantum systems by the quantatized photons that they emit as standardized packets of energy and that we commonly analyze as light of different frequencies.
As a teen trying to understand what quanta were and why they had to be, one afternoon I realized that atoms were like Navy destroyers and cruisers and battleships, firing out quanta in photons of specific energy, just as a ship's guns emitted combat power through bullets and shells of specific size and weight. Life itself also relies on the quanta of individual organisms.
Indeed, just as the laws of physics make atoms the single smallest particle of elements, quanta are nature's way of organizing energy into distinct packets. As complicated as the subject is, the basic concept is relatively simple, that because matter has mass and structure, energy is also naturally parcelled out to accommodate those constraints and measures.
I agree with most of your statement. There are further problems that must be surmounted. One is the observation paradox, a known state in quantum physics where the mere observation of an event changes the result.
I don’t get what else there is between on/off.
What about 3 colors, like a traffic light?
Or 21 gears like a mountain bike?
It is easy to imagine things with more than 2 states - the trick is finding something that ALSO is microscopic, the cells of which are organized
into assignable addresses, can be easily accessed, read, and switched between states.
Silicon has all the required properties to lend itself to supercomputing - but each cell has only 2 states.
By the way, I’ve read your posts - I like your modesty, but you are a lot smarter than you sometimes let on.
:-)
Go right to the hardest case, eh? The observer paradox goes to issues that seem to be at the root of existence itself, with material things seemingly subordinate to consciousness. No wonder that surveys in academia now indicate that physicists are more inclined to believe in God as possible than are social scientists.
I’ll be wiggling my big toe all morning.
Watch ‘em accidentally quantum-clone a few billion Obamas.
