Physicists have created the world’s heaviest Schrödinger’s cat, bringing the bizarre behavior of the quantum world to larger scales than ever before.

The trick, performed by vibrating 100 million billion atoms inside a sand-grain-sized sapphire crystal, created the world’s heaviest quantum superposition as the crystal simultaneously oscillated in two different directions. Despite weighing just 16 micrograms (16 millionths of a gram), the crystal is trillions of times heftier than the molecules put into previous large-scale quantum states, and is visible to the naked eye. 

Taking its name from Erwin Schrödinger’s famous thought experiment, the new Schrödinger’s cat crystal could be used to design more robust quantum computers and reveal clues behind why quantum effects are not seen in the real world, according to the researchers. Their findings were published April 20 in the journal Science (opens in new tab) .

“Of course, in the lab we can’t realize … an experiment with an actual cat weighing several kilograms,” lead author Yiwen Chu, a physics professor at the Laboratory for Solid State Physics at ETH Zurich, said in a statement. But “by putting the two oscillation states of the crystal in a superposition, we have effectively created a Schrödinger cat weighing 16 micrograms.”RELATED STORIES—Largest objects ever get cooled down to their ‘quantum limit’

In Schrödinger’s thought experiment, the weird rules of the quantum world are envisioned by imagining a cat placed inside an opaque box with a poison vial whose release mechanism is controlled by radioactive decay — a completely random quantum process. Until the box is opened and the cat is observed, Schrödinger said, the rules of quantum mechanics mean that the unfortunate feline should exist in a superposition of states, simultaneously dead and alive.

As most quantum effects typically decohere and disappear at macroscopic scales, Schrödinger’s analogy was meant to demonstrate the fundamental differences between our world and the world of the very small. Yet no hard limit exists between the two realms, enabling physicists to begin cajoling complex, near-macroscopic-scale objects into showing freaky quantum behavior.

To achieve this, the physicists connected the vibrating part of the sapphire crystal to a superconducting circuit, shaking it in such a way that it began to vibrate in a superposition of two directions at once. 

Then, to confirm that they had indeed created a quantum cat, the researchers measured the spatial separation of the crystal’s two vibrating states. Though the vibrations were subatomic in scale (vibrating over a distance of a billionth of a billionth of a meter), they were clearly distinguishable from random thermal and quantum vibrations — the cat was real.

In the future, Chu would like to increase the mass of the Schrödinger’s cat crystal even more, creating macroscopic quantum objects that could be used to more robustly store information in quantum computers, look for gravitational waves and dark matter, and figure out how quantum effects disappear at the scale of real cats.

Bob Geldof accuses Israeli authorities of ‘lying’ about starvation in Gaza

Bob Geldof accuses Israeli authorities of 'lying' about starvation in Gaza

Bob Geldof has accused the Israeli authorities of “lying” about starvation in Gaza – after Israel’s government spokesperson claimed there was “no famine caused by Israel”.

Earlier this week, David Mencer claimed that Hamas “starves its own people” while on The News Hour with Mark Austin, denying that Israel was responsible for mass hunger in Gaza.

Appearing on Sunday Morning with Trevor Phillips, Geldof said the claims are false.

Israel challenged on starvation in Gaza

Mr Phillips asked the Live Aid organiser: “The Israeli view is that there is no famine caused by Israel, there’s a manmade shortage, but it’s been engineered by Hamas.

“I guess the Israelis would say we don’t see much criticism from your side of Hamas.”

In response, Geldof said “that’s a false equivalence” and “the Israeli authorities are lying”.

The singer then added: “They’re lying. [Benjamin] Netanyahu lies, is a liar. The IDF are lying. They’re dangling food in front of starving, panicked, exhausted mothers.

“And while they arrive to accept the tiny amount of food that this sort of set up pantomime outfit, the Gaza Humanitarian Front, I would call it, as they dangle it, then they’re shot wantonly.

“This month, up to now, a thousand children or a thousand people have died of starvation. I’m really not interested in what either of these sides are saying.”

Gaza: ‘This is man-made starvation’

In the interview with Mark Austin on 23 July, Mr Mencer added: “This suffering exists because Hamas made it so. Here are the facts. Aid is flowing, through the Gaza Humanitarian Foundation. Millions of meals are being delivered directly to civilians.” He also claimed that since May more than 4,400 aid trucks had entered Gaza carrying supplies.

It comes after MSF, also known as Doctors Without Borders, warned 25% of young children and pregnant women in Gaza are now malnourished.

The charity said Israel’s “deliberate use of starvation as a weapon” has reached unprecedented levels, and said that at one of its clinics in Gaza City, rates of severe malnutrition in children under five have trebled over the past two weeks.

MSF then called the lack of food and water on the ground as “unconscionable”.

Aid waiting to be distributed in Gaza

In a statement to Sky News, an Israeli security official said that “despite the false claims that are being spread, the State of Israel does not limit the number of humanitarian aid trucks entering the Gaza Strip”.

It then blamed other groups for issues delivering aid. They said: “Over the past month, we have witnessed a significant decline in the collection of aid from the crossings into the Gaza Strip by international aid organisations.

“The delays in collection by the UN and international organisations harm the situation and the food security of Gaza’s residents.”

The IDF also told Sky News: “The IDF allows the American civilian organisation (GHF) to distribute aid to Gaza residents independently, and operates in proximity to the new distribution zones to enable the distribution alongside the continuation of IDF operational activities in the Gaza Strip.

“Following incidents in which harm to civilians who arrived at distribution facilities was reported, thorough examinations were conducted in the Southern Command and instructions were issued to forces in the field following lessons learned.

“The aforementioned incidents are under review by the competent authorities in the IDF.”

You can watch the full interview on Sunday Morning with Trevor Phillips at 8.30am tomorrow.

Honda takes a page from Tesla playbook, launches new insurance business

Say what you will about Elon Musk, but Tesla has changed the way that millions of people buy cars and, by extension, car insurance. Now, Honda is taking a page from Tesla’s successful playbook and launching its own in-house insurance business. Enter: Honda Insurance Solutions.

Honda Insurance Solutions is being launched as a fully licensed insurance agency serving the insurance needs of Acura and Honda customers, but it’s not stopping at competitive pricing and coverage options for Honda cars and motorcycles. Honda Insurance Solutions promises to go several steps beyond Tesla’s offering with coverage for trailers, RVs, homes, and even pets.

“Honda Insurance Solutions offers customers access to coverage through a brand they know and trust,” says Petar Vucurevic, President, American Honda Insurance Solutions, LLC and Senior Vice President, American Honda Finance Corporation. “Insurance is a key touchpoint in the vehicle ownership journey, and we aim to deliver a superior experience tailored to the unique needs of each customer, while promoting safer driving and increased peace of mind on the road.”

The company says the launch of its new insurance business is just part of Honda’s broader digital vehicle sales platform strategy, with future plans to integrate insurance offerings into new products.

Electrek’s Take

It’s important to note some of the key differences between Honda’s insurance offering and Tesla’s. Honda isn’t offering discounts, they’re not bundling insurance premiums into the vehicle financing, and they’re not building their insurance offerings into their dealerships’ checkout/F&I offices. Not yet, anyway.

What Honda is doing right now is deepening relationships with its existing customers and finding ways to make money on products it hasn’t sold them – whether that’s the Harley parked in the garage next to their Prologue or the garage itself.

It’s a smart play. And, once Honda figures out a way to cut franchise dealers out entirely and go to a direct sales model, it’ll look even smarter.
