As 2019 winds to a close, the journey towards fully realised quantum computing continues: physicists have been able to demonstrate quantum teleportation between two computer chips for the first time.

Put simply, this breakthrough means that information was passed between the chips not by physical electronic connections, but through quantum entanglement – by linking two particles across a gap using the principles of quantum physics.

We don't yet understand everything about quantum entanglement (it's the same phenomenon Albert Einstein famously called "spooky action"), but being able to use it to send information between computer chips is significant, even if so far we're confined to a tightly controlled lab environment.

"We were able to demonstrate a high-quality entanglement link across two chips in the lab, where photons on either chip share a single quantum state," explains quantum physicist Dan Llewellyn from the University of Bristol in the UK.

"Each chip was then fully programmed to perform a range of demonstrations which utilise the entanglement."

Hypothetically, quantum entanglement can work over any distance. Two particles get inextricably linked together, which means looking at one tells us something about the other, wherever it is (in this case, on a separate computer chip).

To achieve their result, the team generated pairs of entangled photons, encoding quantum information in a way that ensured low levels of interference and high levels of accuracy. Up to four qubits – the quantum equivalent of classical computing bits – were linked together.

So in general terms how much faster would a quantum computer be?

What would be some other projected benefits of a quantum computer?

Here's the problem with FTL computing as it's still a ways off unless there is a breakthrough. Light is very fast obviously, but doesn't get far so we need power to get it to go further. If you can generate the power required, then it brings along with it heat transfer and so you need to cool it down.

I think for today, what we have is fiber optic cable for communications. However, that means we have to stay in the ground for it and that limits mobile computing and communications. Thus, wifi is what we got for it.

ETA: The above and following was for ding. That said, I'm open to other ideas such as quantum computing. Just haven't seen it live yet. Will bolo for it though.

What do you have? I've been retired from my field for several years so probably the stuff I have is outdated.

Quantum computing needs to be at such a high frequency that low power is used or required. If you do this in the 0.2um to 1.2um bands you need clear line of site. QAM can be adapted to this region but dust and other thing can interfere with it. It is not without problems and limitations.

I rather see photonic computing first or some variation of it. I think you're stuck in this quantum entanglement which is still far off.

'In a paper published today in Physical Review Letters, the researchers split one cavity into two, each with a designated task. A smaller cavity handles the efficient extraction of photons, while an attached large cavity stores them a bit longer to boost indistinguishability.

Compared to a single cavity, the researchers’ coupled cavity generated photons with around 95 percent indistinguishability, compared to 80 percent indistinguishability, with around three times higher efficiency.

“In short, two is better than one,” says first author Hyeongrak “Chuck” Choi, a graduate student in the MIT Research Laboratory of Electronics (RLE). “What we found is that in this architecture, we can separate the roles of the two cavities: The first cavity merely focuses on collecting photons for high efficiency, while the second focuses on indistinguishability in a single channel. One cavity playing both roles can’t meet both metrics, but two cavities achieves both simultaneously.”'

Generating high-quality single photons for quantum computing

MIT researchers have designed a two-cavity single-photon quantum emitter that generates, at room temperature, more indistinguishable single photons that could be useful for practical quantum computers, quantum communications, and other quantum devices.

This is not really about quantum computers at this point, we are at the same point now as we were when a single vacuum tube was a single transistor.

It's not that there are no laws governing quantum properties as I am sure that there are. However, there are no humans who truly understand the quantum world, and that most certainly included Werner. Referencing Werner is like referencing Watson and Crick and claiming they understood DNA because they discovered it. There is still no explanation for DNA, just descriptions

As for the uncertainty principle, Werner might have been far more successful if he was born today, so would Albert who would never have proclaimed that the universe was not expanding. So Al was wrong and so was Werner, we must build on the past, not learn it and accept it

NASA says galaxies are moving at five times light speed at least.

Physicist agree so they invent mythical dark matter

So the more we learn, the less we know

Totally cool

One can not really be correct or incorrect unless the answer is known. I think Heisenberg may have birthed generations of thinkers determined to measure the not measurable and found it rather easy.

The uncertainty principle might need to be amended to, that the position and the velocity of an object cannot both be measured exactly, at the same time, even in theory, (at this point in time) Time also not being defined properly

You can look at quantum computing as it exist now at it's infancy or you can also look at the wider entanglement possibilities which may or may not overlap.

are you saying that info was transferred instantly from one object to another ? if thats what you are saying then it is also outside of what we know about time and space ! that would be a big big deal !

I think that has been known for a long time. I remember reading about that like years ago.

Or maybe i am confused....this stuff though extremely interesting is way over my head.

The quantum world is mind-bogglingly weird

At the smallest scales, particles are ghostly and ill-behaved. No one understands them, but that doesn’t keep scientists from trying.

Some are saying the transfer or entanglement is in fact instant with no wires needed. Others say they have measured a speed of 10000 times light speed or 10,000 * 186,000 miles per second or 1,860,000,000 miles per second which for all points on planet Earth is effectively instant to any human observer. Yes you are correct, scientist are in agreement that observations are contrary to some or all of established physics. Some researchers are now even questioning the existence of the universe because mathematically Newtons and Einsteins gravitational models are impossible.

It's technically way over everyone's head at this point as the standard physics model is breaking down. Note that it is not physics that is breaking down, but many long held beliefs that we now are seeing were based upon suppositions and not actual fact. It does not matter whether one looks to the quantum particle small or expand to the known universe one finds far more questions than answers.

The truly ignorant are those who will tell you they know or that can't be as science is entering a new avenue of understanding which must always begin with the question, why?

 

[Wuwei]

So why exactly is it that so many are denying these breakthroughs and flat out claiming that no information can and is being sent using entangled particles?

There may be a confusion between transferring information versus communication. No information exists in simple entangled particles since both are in an indeterminate state (a superposition of two possible states.) Measuring the state of one particle immediately fixes the state of the other particle. In that sense particle state information transfer is instantaneous.

Suppose you want to communicate instantly to Bob going to Alpha Centauri. You start out by entangling a particle pair. Then send one particle to Alpha Centauri with Bob. You want Bob to instantly tell you if he has enough fuel to get back. Particle spin +1 means “yes” spin -1 means “no”.

In order to communicate a specific state, +1 or -1 Bob has to force his particle's entangled state to the one that is consistent with the message he wants to send. The act of forcing the particle's state causes decoherence – Bob's particle state is what he wants, but your particle state is still a superposition of the two states – no information is communicated.

Summary:
Simply measuring one particle's state changes the other particle's state – both states are opposite (because of entanglement) but a random message is instantaneously sent.

Bob's can force his particle's state, but entanglement is aborted and leaves your state indeterminate.

The teleportation of a qubit is not new, but doing it on a single chip is a great technological achievement. Thank you.

Without all that crap of above, with a simple home made experiment I can prove without doubt that you observe the entire universe in its current and present status.

I discovered the Law of Perception which rules that we and our instruments perceive the universe in its present only.

This is telling you that regardless of distance and without the need of considering any speed for light, you are receiving the present information of what is happenming right now in the cosmos from any place of the universe.

With this Law of Perception, the superfluous idea that we observe galaxies as they were in their past, is a debunked idea invented because ignorance.

I can see that finally my great discovery is being backed up. This Law I discovered was also registered for copyrights at the Library of Congress.

The long answer:
The Real Reasons Quantum Entanglement Doesn't Allow Faster-Than-Light Communication
.

The only confusion is yours as communication is the transfer of information, this is true no matter what the medium used for the transfer such as amplitude or frequency modulation radio waves, microwaves, infrared, visible light, fiber optic, sound frequency's or digital info carried via any of these mediums. When computers consisted of mountains of vacuum tubes they were inefficient and cumbersome, yet with the conglomeration of minds that saw the potential if the tubes could be shrunk, the modern microchip was born. You lack the required vision to move ahead as you persist in using the words can't be measured and you believe in arbitrary speed limits set by a man incapable of combing his own hair and who never in his entire life did a single experiment which is why Hubble destroyed Einsteins ignorant hypothesis that the universe was not expanding. Hubble experimented with and came to a different conclusion the newest measurements have entire galaxies moving at 5 times light speed something that you again say can't be happening.

Well there is no can't be with the universe, because there is no definition of what the universe is, where it came from or where it is going, all we have are observations that do not match with any set of physical values whatever. The same is true of quantum entanglement which is currently in a similar state as what tubes were in the 40's and 50's. Do you think you could get a job saying that it can't be done?

You stay there canting your life away, I'm still moving ahead and not slowing for squat
