I don’t claim to be the expert on all things Quantum by no stretch; however, this is an amazing discovery and huge step forward for Quantum.

Quantum gas and liquid/ ferrofluid (quantum fluid made of tiny magnets). Now there’s a concept. Q-Dots as ferrofluid flowing through out your system (which is already comprised of about 72% H2O; think about how liquid Q-Dots can be easily absorb as a liquid and given your brain, heart, etc. run on electro charges and sensors; it could definitely open the discussion why even bother with nuero implants when Q-ferrofluid could actually be absorbed and manipulated to target the right areas for fighting diseases or improving brain functions.

The world of quantum mechanics happens only in small scales around a few nanometers. In this nanoworld, particles can behave like waves, and vice versa and have only some probability to be in a particular region. These effects can be directly observed in ultracold dilute gases. For this purpose thousands or a million atoms are cooled down to a few billionth of a degree above absolute zero. At such low temperatures particles become indistinguishable und unite collecitvely to a single giant matter wave called Bose-Einstein condensate which has astonishing properties. The matter wave flows as quantum fluid practically without inner friction, thus it is namedsuperfluid.

Researchers around Tilman Pfau at the Center for Integrated Quantum Science and Technology IQST in Stuttgart (Germany) created such a quantum fluid made of tiny magnets – that are atoms of the most magnetic element dysprosium. They call it “quantum ferrofluid” since it is superfluid and has magnetic properties similar to classical ferrofluids. Ferrofluids consist of ferromagnetic nanoparticles dissolved in oil or water. When a strong magnetic field is applied perpendicular to the surface of the ferrofluid it undergoes a so-called Rosensweig instability. The surface is no longer smooth like normal fluids, but it generates a regular thorny surface resembling a hedgehog. From the point view of the tiny magnets in a ferrofluid, every south- and northpole attract each other. Therefore, it is energetically favourable to be on top of each other along the field direction, so the fluid grows peaks out of the smooth surface.

For their investigations the researchers from Stuttgart created a quantum ferrofluid with 15,000 atoms and induced a magnetic instability. They observed then the emergence of regular patterns consisting of microscopic droplets, similar to the Rosensweig instability of ferrofluids. Each droplet has a radius smaller than 1 µm and their existence was not expected with the current state of research on these systems. Their observation could thus lead to a new field of research, as the researchers expect quantum fluctuations, related to Heisenberg’s uncertainty principle,to play an important role in the droplet existence. These quantum fluctuations allow a unique state of matter that connects opposite properties of gases, crystals and superfluids. This connectioncould be the path to a so-called supersolid, a spatially ordered material with superfluid properties.

I shared this same point of view yesterday; and glad to see Princeton shares the same perspective on Quantum and it’s abundant capabilities. Again; Quantum is going to truly change (if not everything) almost everything that we consume, use, and interact with even in raw material enrichment will benefit from Quantum.

Claire White, an assistant professor of civil and environmental engineering and the Andlinger Center for Energy and the Environment, studies ways to make building materials more sustainable. It turns out that cement production creates a lot of carbon dioxide, so much that it accounts for roughly 5 to 8 percent of man-made carbon dioxide emissions globally. White and her team are developing new types of cement using industrial byproducts such as coal fly ash and blast-furnace slag. They make these materials more durable by adding nanoparticles.

Watch Assistant Professor Claire White explain her research on a more sustainable type of cement.

I still get a kick out of these types of articles because it is the classic “Fear of the Unknown” getting folks worked up. A) we don’t have enough information to confirm or not confirm whether humans will totally disappear and morph into a half Human and half machine species. B) it doesn’t scare me at all because I will make the choice if I decide that I want or need an implant. And, if I do, then more than likely it was to help me beat a disease like cancer or to enrich my life somehow just like I would opt for a surgery or procedure today. Nothing more.

However, there is one thing that is certain and that is Quantum Technology itself is going to truly transform everything in our lives. And, I mean EVERYTHING (medical/ healthcare, manufacturing, AI, devices, communications, services, raw materials enrichment, etc.).

Ipswich-based Futurologist Dr Ian Pearson has explained how technology will impact on our evolution, such as the rise of Homo optimus — and how it could affect our pets’.

Every time we have a step forward with Quantum for industries like technology, wireless & telecom, manufacturing, energy, etc.; we also gain a steps for healthcare in so many ways such as Q-DOTs eradicating super Bug Viruses, Brain Mind Interface capabilities, implants, etc. Why I luv Quantum so much.

Emergent phenomena are common in condensed matter. Their study now extends beyond strongly correlated electron systems, giving rise to the broader concept of quantum materials.

Researchers have discovered a new method of heat conduction that is a ten-thousand-fold improvement over earlier attempts. The novel invention forms a necessary step in the creation of super-cooled quantum computing.

A group of Finnish scientists at Aalto University have made a stunning breakthrough in heat transference, and the implications are potentially revolutionary.

The discovery made by quantum physicist Mikko Möttönen and his team involves something known as “quantum-limited heat conduction,” a rather cumbersome term for, simply, the most efficient possible heat conduction from one point to another.

Did you know that Quantum Theory does not know how probabilities are implemented in Nature? And for that matter neither does any other physical theory. Why? Or why not? The closest Quantum Theory comes to explaining probabilities, is to guess that a particle’s wave function is related to its probabilities. That’s it!

Why do we need to ask this question? Commercial opportunities. Imagine if you could control where a photon localizes (captured by an atom). Particle detectors become significantly more sensitive. Boring? No, in fact, DARPA aims to precisely spot single photons and explore the Fundamental Limits of Photon Detection. Anti-stealth is one application. Imagine if you didn’t need 1,000,000 radio wave photons to determine an aircraft’s radar signature, but only a 1,000?

Using probabilities to control photon switching “circuits”, probability switches. Imagine an empty box with optical cables entering and exiting. These probability switches cause photons to exit through different optical cables by controlling where they localize within the box. What if we could build computers with materials lighter than a feather to switch photon paths, instead of heavy silicon or gallium arsenide to switch electron paths? Imagine how fast these switches could operate, as no matter is involved.

Things keep getting better and better for Quantum and Brain Interfaces/ implants as well. What you have to love is the fact how Quantum Dots and it’s research helps us both technically and medically as well. When I reported 2 weeks ago about Quantum Q-Dots; what I did not share is how Q-Dots could be leveraged to wipe out many Super Bug Viruses. And, this is why things are really stepping up in AI/ Robotics, Brain Mind Interfaces, micro bots, etc. Definitely on a path to singularity.

Plasmonics enable wavelengths of light to shrink to the nanometer scale.

Another major leap forward in Quantum; researchers have been able to transport heat consistently ten thousand times further than ever before. This will enable Quantum technology to be leveraged in across multiple areas of manufacturing (clothing, etc.), energy, and electronics due to its heat conductive properties.

Heat conduction is a fundamental physical phenomenon utilized, for example, in clothing, housing, car industry, and electronics. Thus our day-to-day life is inevitably affected by major shocks in this field. The research group, led by quantum physicist Mikko Möttönen has now made one of these groundbreaking discoveries. This new invention revolutionizes quantum-limited heat conduction which means as efficient heat transport as possible from point A to point B. This is great news especially for the developers of quantum computers.

(Phys.org)—Although in theory it may seem possible to divide time up into infinitely tiny intervals, the smallest physically meaningful interval of time is widely considered to be the Planck time, which is approximately 10-43 seconds. This ultimate limit means that it is not possible for two events to be separated by a time smaller than this.
