Qbits 30 Meters Apart Maintain Entanglement Across Refrigeration Systems
The experiment wasn’t the first to show that local realism isn’t how the Universe works — it’s not even the first to do so with qubits. But it’s the first to separate the qubits by enough distance to ensure that light isn’t fast enough to travel between them while measurements are made. And it did so by cooling a 30-meter-long aluminum wire to just a few milliKelvin. Because the qubits are so easy to control, the experiment provides a new precision to these sorts of measurements.
And the hardware setup may be essential for future quantum computing efforts… Everyone working with superconducting qubits says that we will ultimately need to integrate thousands of them into a single quantum computer. Unfortunately, each of these qubits requires a considerable amount of space on a chip, meaning it gets difficult to make chips with more than a few hundred of them. So major players like Google and IBM ultimately plan to link multiple chips into a single computer (something the startup Rigetti is already doing).
For tens of thousands of qubits, however, we’re almost certainly going to need so many chips that it gets difficult to keep them all in a single bit of cooling hardware. This means we’re going to eventually want to link chips in different refrigeration systems — exactly what was demonstrated here. So this is an important demonstration that we can, in fact, link qubits across these sorts of systems.
Or, as long-time slashdot reader nounderscores puts it, “Imagine a beowulf cluster of these.
“The Qbits that Simon Storz et al at ETH Zurich entangled at the ends of 30m of cryogenically chilled wire not only put the last nail into the coffin of hidden variable theory by being so far apart, they also allow quantum computing to scale to multiple refrigeration systems.”

Shopify sells 6 River Systems to new owner
Shopify last week announced that it would be the latest big tech firm to undergo mass layoffs. The company is cutting 20% of its 11,600-person staff. The news arrived during earnings that beat Wall Street expectations, shooting its stock price up as a result. Also included in the announcement was news that the Canadian e-commerce […]

Park Beyond’s array of simulation systems is more dizzying than its weird rides
For the past while, I’ve been playing a closed beta build of Park Beyond, and let me tell you, I am very bad at it. I can just about (by the skin of my teeth) make a profitable park, but my god, that park will have the worst layout you’ve ever seen in your cursed, vomiting in the bins at a Disneyland life. But look, if the park works, it works, right? The shareholders can’t complain!
Thing is, much like with the internet or your mum’s relationship with the binman, theme park simulators can really change while you’re not paying attention. While part of Park Beyond’s selling point is making literally impossible rides via the aptly-named method of Impossification (an upgrade to rides you buy by spending units of amazement gleaned from your slack-jawed guests, in order to strap a canon to a rollercoaster), I really was not prepared for how simulation-y the simulation bits are.
