In a groundbreaking use of teleportation, critical units of a quantum processor have been successfully spread across multiple computers, proving the potential of distributing quantum modules without compromising on their performance.
While the transfer only took place over a space of two meters (about six feet) in an Oxford University laboratory, the leap was more than enough to emphasize the feasibility of scaling quantum technology by teleporting quantum states across an 'internet' of connected systems.
Teleportation is a quirk of physics that only makes sense through a quantum lens, where objects exist in a blur of possible characteristics until processes of measurement force them to adopt each state.
By mingling the undecided states of different objects in an act known as entanglement, and then carefully choosing the right kinds of measurements to make on one, it's possible to use the answers to force an entangled object some distance away to adopt (and destroy) the original object's quantum identity.
It might not be the kind of teleportation that would beam passengers through the vacuum of space in a blink, but it's perfect for sharing the blur of information necessary for logical operations in a quantum processor.
"Previous demonstrations of quantum teleportation have focused on transferring quantum states between physically separated systems," says lead author Dougal Main, a physicist at Oxford University.
"In our study, we use quantum teleportation to create interactions between these distant systems."
Where classical computers use binary 'on or off' switches to perform strings of computations on bits of information, quantum computers use mathematically complex distributions of possibilities known as qubits, typically represented in a simple feature of an uncharged particle such as a charged atom.
To make this process practical, hundreds or even thousands of such particles need to have their yet-to-be-decided states entangled with one another in a restricted fashion, without intrusive objects weaving their own possibilities in and messing up the calculations.
Scaling current technology to this level is complicated by obstacles that require error-correcting processes or shielding to preserve the delicate quantum states long enough for them to be measured.
Linking a number of smaller processors across a network to create a kind of quantum supercomputer is another solution. While quantum information can be transmitted in the form of a light wave, the potential for its state to be irreversibly corrupted along the way makes it an impractical option.
Teleportation requires the receipt of measurements the old-fashioned way – through reliable binary data. Once sent, operations at the receiving end can tweak their own entangled particle until it effectively looks like the original.
The all-important quantum blur of the teleported spin state in the Oxford University experiment was an 86 percent match with the original, more than good enough for it to serve as a logic gate for a simple operation known as a Grover's algorithm, which succeeded with 71 percent efficiency across the two quantum processors.
"By interconnecting the modules using photonic links, our system gains valuable flexibility, allowing modules to be upgraded or swapped out without disrupting the entire architecture," says Main.
Having options for restructuring a quantum network could diversify the applications for such technology, repurposing networks of computers into cowtools that can measure and test physics at its most fundamental level.

all of my life on the internet, I'd read Americans smugly declaring that the only reason anywhere that wasn't North America, Western Europe or Japan was a mess, was because the people there obviously deserved it. they were inferior and couldn't handle democracy. they also proclaimed loudly that any dictatorship would never fly in the US because they love freedom and would demonstrate the second anything resembling a dictatorship came to pass in the US.
now Trump is president and "joking" about running a third term, being a king etc.. and what do they do? absolutely nothing. they tow the line and watch as America delves further into authoritarianship.
serves you right for all the times you claimed you were more civilised you motherlovers.

Wow. Congress just tabled a bill that would *actually* kill open-source. This is easily the most aggressive legislative action on AI—and it was proposed by the GOP senator who slammed @finkd for Llama.

I don't really have any gay friends. One guy I follow on the gram and I just found out cuz of valanetiMes day.
They seem very performative to me. Which is not a very male trait imo. Are they just making themsleves men for the female gaze? Like speaking English with a foreign accent vs being a native speaker. A lot of women seem to like them.
I was loose friends with a few lesbians in high school but I thought I had nothing in common with them. I'm just curious, what do people see in them? How like men are they? Do you think they truly like what they're interested in?
Don't mean to ruffle feathers! 🪶

Can't say I'm surprised as the Grammys aren't what they used to be, but I think Lainey should have won that category. Really anyone except Beyoncé. (7)

My bad, I didn't realize you would take that to mean those two elements alone are pop. That isn't what I meant.Well no duh. I didn't say take Beyoncé out. I mentioned Miley because Miley's vocals sound country. She has a drawl and grit. Not saying you have to have those particular elements but there are clearly vocal differences from a pop singer and a country singer. If Chris Stapleton, Morgan Wallen, or Lainey Wilson sang a song without a twangy guitar or overly hokey lyrics you will still recognize it as country. That was my point. If I took Beyoncé song with just Beyoncé and no twangy guitar or Miley Cyrus… it would just sound like one of her pop songs. I really don't want to harp you anymore but I can't just ignore this lol. Just as a twangy guitar doesn't make a song country I don't think corny country sounding lyrics make a song country. I don't think Lil Nas X singing about a a horse makes him a country singer lol. It's a great song and is fun. But, to me, it lacks any depth... (1)

I mean there is definitely a vibe of her using country like a costume. Studying country aspects and incorporating it into an album doesn't make the album any better. No more than a country artist studying R&B and releasing some corny album with corny lyrics. Like "this ain't Texas, ain't no hold em"? Come on… and that was the most popular song on the album. Like what metric are we using to call this good? (1)

The downward spiral keeps going, yet another CT sub has fallen. 😭 Cumboys and cumgirls are the most persecuted people on reddit. Nick leaves, and now reddit kicks us off again. Dark times.
Many NSFW subs recently got banned for being "unmoderated" actually like /r/drugs. reddit sucks butt.
/r/redscarepod is next in line for the rope, betting on it.
Edit: NVM it's back up

Some nonsense article has come out which cites:
A number of people connected to the Trump team have talked about "regime change" in the UK
'a number of people talking' holy shit total journ*list death
I didn't read it but basically it's about orange daddy wanting to get rid of
starmer so naturally it caused some spilled cups of tea in the cute twink subreddit.
regime change? heh good luck with th-
Is Keir Starmer really the last bastion of hope for a world without fascist leaders? I'm scared.
Hey remember like six months ago when he released 1700 violent offenders and suspended due process in order to jail people who commented emojis on facebook posts?
- man who can't purchase a knife without submitting a video of him next to his passport
I would think a UK headline "United Kingdom wants a regime change in the US" might prove popular.
We have about as much cache on the world stage as, say, Burundi. Paul Kagame publicly bent us over and this chap thinks he's

Coming from reddit user who was absolutely convinced Musk and his Bots are going to destroy democracy any day now?
stop you from meeting King Charles even though we have no power to do that
wow talk about soft power! We've really got Drumpf over a barrel on this one
I actually thought this was a joke until someone replied
clapping like a seal
Starmer could be described as a lot of things, socialist? Don't be silly…
Frick Trump and his regime. We need to keep his influence away from our way of life.
This guy's entire life is football and sneeding about Trump and Musk
So we're happy to be bullied by the US now, but the EU was an issue?
Reddit liberals are now Enochposting. Chuds really are playing eight-dimensional chess.
