Quantum Technology

On quantum engineering

Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory and the University of Illinois Urbana-Champaign have made a breakthrough in understanding and controlling quantum emitters. The work has been published in Advanced Materials.
At the Center for Nanoscale Materials (CNM), a DOE Office of Science user facility at Argonne, the team used a state-of-the-art, specialized microscope called QuEEN-M (Quantum Emitter Electron Nanomaterial Microscope) to pinpoint and even create quantum emitters in an ultrathin material known as hexagonal boron nitride.


Recently, physicists at the National Institute of Standards and Technology (NIST) achieved new levels of control over molecules. In a study published in Physical Review Letters, they were able to manipulate a calcium hydride molecular ion—made up of one atom of hydrogen and one atom of calcium, with one electron removed to make it a charged molecule—with almost perfect success. And this control opens possibilities for quantum technology, chemical research and exploring new physics. "To control a particle, we need to pinpoint it in one specific state. A molecule has a large number of states it can be in because of its rotation and vibration," said Dalton Chaffee, lead author on the paper. "This, in essence, is what makes molecules so much harder to control than atoms."

I submit my whole miserable life as evidence.
You know how with black holes---if you go deep enough--the only direction is down?

There I am.

I'm sorry, I just (snif') took the following news badly:

Sudden breakups of monogamous quantum couples surprise researchers

I knew as soon as they took prayer out of schools that this would happen.

When I get depressed, I get hungry--how do I keep this thing from flashing 12:00?

Until now, superradiance was mostly known for making quantum systems lose their energy too quickly, posing challenges for quantum technologies. But a new study published in Nature Physics turns this idea on its head—revealing that collective superradiant effects can instead produce self-sustained, long-lived microwave signals with exciting potential for future quantum devices.

Self-induced superradiant masing - Nature Physics

Superradiance is usually driven by light-mediated couplings, leaving the role of direct emitter interactions unclear. Now, it is shown that dipole–dipole interactions in diamond spins drive self-induced pulsed and continuous superradiant masing.

DARPA backs Diffraqtion to demo ‘quantum camera’ for space, Earth surveillance​

DARPA backs Diffraqtion to demo 'quantum camera' for space, Earth surveillance - Breaking Defense

Only recently emerging from stealth, the MIT-UMD spinout is planning constellations of small, low-cost ISR satellites for multiple military missions.
breakingdefense.com breakingdefense.com
The Pentagon’s Defense Advanced Research Projects Agency (DARPA) is funding startup Diffraqtion to develop what the company said in an announcement today is “a first-of-its-kind quantum camera” capable of providing near-real time imagery at “up to” 20 times faster than that enabled by current optical surveillance cameras.

“This camera is very good because it is very fast and can look at very small things,” Galatsanos said.

He added that it also is capable of providing high-resolution imaging during daylight — something that is very difficult, if not impossible, for most current optical telescopes.

“When you have an asset in space you want to keep persistent custody, so you want tracking especially during daytime,” he said. “The biggest thing that we provide is to enable persistent custody and change detection also during daytime.”

Quantum Freezing
Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information loss. Physicists have long known of a strange exception, called dynamical freezing, when quantum systems shaken at precisely tuned frequencies evade these laws.

However, those same quantum processes occur every day inside tree leaves at room temperature and with 100 x 100 energy efficiency. The secret of photosynthesis is vital for our future, it is necessary to invest more, the possibility of feeding sunlight for future extraterrestrial colonies depends on it, freeing them from hydroponic agriculture and stupid solar panels.

Add CO2 scrubbing for lifesupport system to the list of vital priority. Despite 100 years of research into it we are still at square one, though.
Anyhow, the problem is quantum technology based on photonic switches requires a lot of area and volume due to loops/guides being larger than electrons or ions based alternatives.

In the news

A new study, published in Physical Review Letters, reports that scientists have successfully imaged the formation of cavity-induced density waves induced by laser light in an ultracold quantum gas. Previously, only global signals, such as photon leakage or the peak in energy deposition of a fast charged particle (Bragg peaks), have been used to detect this kind of ordering. Prior to this study, there had been no direct, high-resolution in situ imaging of cavity-induced density-wave order in ultracold gases.

This configuration, featuring minimal Kitaev chains and topologically unprotected Majorana states, is referred to in the literature by the term "poor man's Majorana." Although some researchers condemn the term, the majority have ultimately accepted it and abbreviate it as PMM.
