The optics are just the medium through which the qubits are entangled, the interesting part isn't the lasers but the interaction between physically-separated qubits.

You could theoretically accomplish the same thing by physically bonking the qubits together so that they interact via nuclear forces instead of the electromagnetic field, like they did with entire molecules at Durham University a few weeks back: https://www.msn.com/en-us/news/technology/world-first-quantum-entanglement-of-molecules-at-92-fidelity-uk-achieves-magic/ar-AA1xfHI9

I don't disagree, but I think the bigger problem is journalists who misunderstand the topic and erroneously imply that "quantum" can enable faster-than-light or undetectable communication.

“Previous demonstrations of quantum teleportation have focused on transferring quantum states between physically separated systems,” said Dougal Main, from the Department of Physics at the University of Oxford, who led the study.

"In our study, we use quantum teleportation to create interactions between these distant systems. By carefully tailoring these interactions, we can perform logical quantum gates – the fundamental operations of quantum computing – between qubits housed in separate quantum computers.

“This breakthrough enables us to effectively 'wire together' distinct quantum processors into a single, fully-connected quantum computer.”

To simplify, they're not just entangling pairs of photons and sending them out to two systems, but entangling entire qubits that exist on separate systems. This allows the qubits on separate systems to interact with each other without collapsing their superposition, enabling the quantum equivalent of parallel processing.

Rather than two identical Shrodinger's Cats as in entangled photons, the entangled qubits act as one Shrodinger's Cat that's in two places simultaneously.

It might be counterintuitive, but that's genuinely how quantum systems work.

The entangled photons are in a state of quantum superposition until they are measured, and that measurement creates information about the state of both photons.

It's not a process that can be used to transmit classical information, it's a process that transmits identical quantum random numbers to two places at once that can't be intercepted without breaking their identicalness.

He wiped out 6 months of UHC stock price gains overnight and caused Cigna to commit to expanding their accountability, transparency and customer service departments and tie executive compensation to customer satisfaction metrics.

What did peaceful protest get you in the last two decades? Romneycare is all I can think of and the insurance mandate was a huge step backwards that wipes out any benefit that might be seen from the mandatory coverage for pre-existing conditions.

Think of it like an identical pair of Shrodinger's Cats. You can't know if the cat is alive or dead 'til you open the box, but because they're identical you know that the other box will show the same result as your own.

The lasers don't transmit information, they transmit a quantum superposition. The act of measuring this quantum state creates information, and because the photons are entangled, this information includes what was received at both ends.

So the photons that carry the information aren't teleported, but the information itself is because it doesn't exist until it is observed.

Correct. The speed of light is the speed limit of information in the universe.

Entanglement is neat because it allows us to transmit a quantum superposition to two places at once.

It's like an identical pair of Shrodinger's Cats. You can't know if the cat is alive or dead until you open the box, but you do know that the other box will show the same result as yours regardless of where it ends up.

The new thing they've figured out in this article is how to entangle qubits between separate quantum computers, essentially creating a single Shrodingers' Cat that exists in two computers simultaneously which allows them to do the quantum equivalent of parallel processing.

Allow me to oversimplify for the sake of understanding:

Quantum entanglement is a process where the measurable properties of two particles become linked. For example, an entangled pair of photons might share the same polarization, so that when you measure one, you'd also learn the polarization of the other without having to measure it.

That's quantum teleportation in a nutshell, send out an entangled pair of photons and each of the recipients will know what the other got without having to ask. They call it 'teleportation' because the information about who got what doesn't exist until the photons are measured, and can't be intercepted in transit because the act of measuring an entangled particle breaks the entanglement. You physically cannot tap or eavesdrop on a QE link. To do so successfully you would have to be able to capture a photon on the line and transmit an identical copy in its place simultaneously, but the act of measuring takes a non-zero amount of time and even a nanosecond of delay would be obvious to the intended recipient.

Entangled photons are like a pair of identical Shrodinger's Cats, you can't know if they are alive or dead until you open the box, but you do know that both boxes will show the same result regardless of where they end up.

What's new in this article is that they've managed to entangle entire qubits between separate computers, like a single Shrodinger's Cat that exists in two places at once. They'll be able to use this technique to develop the quantum equivalent of parallel processing.

Luigi did more with three bullets than peaceful protest has accomplished in the last 25 years.

The Left isn't divided, it's unrepresented.

The Democrats are a conservative capitalist party, which might be better than a fascist party but it's still right-wing.

It's been the official U.S. policy since Bush Jr. https://en.wikipedia.org/wiki/American_Service-Members%27_Protection_Act

Right? I don't understand why he's quitting, clearly they don't need to keep their opinions to themselves anymore.

I agree with you, except the Democrats are only "left" when compared to Republicans. The USA has a conservative party and a fascist one.

Don't worry, if anyone was going to collapse the false vacuum it'd probably have already happened.

He seems to think Israel is a U.S. client state rather than the other way around. XD

They're rejecting DEI in favor of WEI: White, Entitled, and Inept.

The single most domesticated culture on the planet..

Of course they should. And people who do Nazi expressions on TV should suffer the expected social consequences, because people should be responsible for the things they say and do.

Are you gonna defend everyone who expresses a "history of fucking your mom" this way, too?

Or are you going to admit that appealing to freedom of expression isn't really an argument in defense of a persistent pattern of behavior that includes but did not culminate with a literal Nazi salute?

That is a very difficult argument to make convincingly when we just had an election where the incumbent was forced off the ballot mere weeks from election day and their replacement might have won if she'd been allowed to be a "hope and change" candidate instead of promising to preserve her predecessor's status quo.

You can't dismantle the DNC and put forward a replacement leading candidate in the fall of an election year.

Of course you can. Only the USA has a 2-year election season, every other developed country on the planet does their elections in a matter of weeks.

The discussion on "hold your nose and vote for Harris, to keep trump out" has an unsaid (but often completely said) primer clause of "the DNC is shit and must change, it's a priority of 2025 and beyond."

I haven't seen one Harris voter claiming they were stoked about her or the DNC.

Sounds to me like you should be begging forgiveness from the voters for holding their nose and making the election as close as it was.

Trump IS a moral dilemma

Trump is a consequence of the Democrats' failure to live up to their own name. Bernie would have won in 2016 if the party leadership didn't deliberately shut him out to run "She whose turn it was".

, and given one vote, and no time to change things, the only option is to reduce harm. THEN build a better future.

Cool. So, now that we're past that point, can we please stop playing the blame game and focus our attention on the "building a better future" part?
