Team creates simple superconducting device that could dramatically cut energy use in computing

MIT scientists and colleagues have created a simple superconducting device that could transfer current through electronic devices much more efficiently than is possible today. As a result, the new diode, a kind of switch, could dramatically cut the amount of energy used in high-power computing systems, a major problem that is estimated to become much worse.

Even though it is in the early stages of development, the diode is more than twice as efficient as similar ones reported by others. It could even be integral to emerging quantum computing technologies. The work, which is reported in the July 13 online issue of Physical Review Letters, is also the subject of a news story in Physics Magazine.

"This paper showcases that the superconducting diode is an entirely solved problem from an engineering perspective," says Philip Moll, Director of the Max Planck Institute for the Structure and Dynamics of Matter in Germany. Moll was not involved in the work. "The beauty of [this] work is that [Moodera and colleagues] obtained record efficiencies without even trying [and] their structures are far from optimized yet."

"Our engineering of a superconducting diode effect that is robust and can operate over a wide temperature range in simple systems and potentially opening the door for novel technologies," says Jagadeesh Moodera, leader of the current work and a senior research scientist in MIT's Department of Physics. Moodera is also affiliated with the Materials Research Laboratory, the Francis Bitter Magnet Laboratory, and the Plasma Science and Fusion Center (PSFC).

The nanoscopic rectangular diode—about 1,000 times thinner than the diameter of a human hair—is easily scalable. Millions could be produced on a single silicon wafer.

What temperature does it operate at?

Looks like someone is trying to replicate the LK-99 room-temperature and ambient-pressure superconductor experiment.

Experts are pressing "x to doubt" on the Korean team's claims

We'll see within a week.

Just to be clear, this is not an official successful replication. This remains inconclusive as far as many are concerned.

[raklian]

Hmm....



The paper in question: https://arxiv.org/abs/2307.16892

LK-99 seems to (possibly) be causing the South Korean stock market to fluctuate:



---------------------------

Some are also reporting it's making the news cycle in China as well. Be damned if this isn't the closest to achieving this we've ever seen. If we cross the Rubicon, and big companies like mentioned actually can utilize the materials at scale that quickly...

Expect the stocks to go to hell if this turns out to be a sham tho

If I were a time traveler traveling from the past arriving to this exact moment, I wouldn't have the slightest clue what's going on no matter how smart I am.
