Two-inch diamond wafers could store a billion Blu-Ray’s worth of data
Researchers in Japan have developed a new method for making 5-cm (2-in) wafers of diamond that could be used for quantum memory. The ultra-high purity of the diamond allows it to store a staggering amount of data – the equivalent of one billion Blu-Ray discs.
Diamond is one of the most promising materials for practical quantum computing systems, including memory. A particular defect in the crystal, known as a nitrogen-vacancy center, can be used to store data in the form of superconducting quantum bits (qubits), but too much nitrogen in the diamond disrupts its quantum storage capabilities.
That meant there was a trade-off to make – scientists had to create either large diamond wafers with too much nitrogen, or ultra-pure diamond wafers that are too small to be of much use for data storage. But now, researchers at Saga University and Adamant Namiki Precision Jewelery Co. in Japan have developed a new method for manufacturing ultra-high purity diamond wafers that are big enough for practical use.
Zero-index metamaterials offer new insights into the foundations of quantum mechanics
In physics, as in life, it’s always good to look at things from different perspectives.
Since the beginning of quantum physics, how light moves and interacts with matter around it has mostly been described and understood mathematically through the lens of its energy. In 1900, Max Planck used energy to explain how light is emitted by heated objects, a seminal study in the foundation of quantum mechanics. In 1905, Albert Einstein used energy when he introduced the concept of photon.
But light has another equally important quality, known as momentum. And as it turns out, when you take momentum away, light starts behaving in really interesting ways.
Physicists Developed a Superconductor Circuit Long Thought to Be Impossible
By exchanging a classical material for one with unique quantum properties, scientists have made a superconducting circuit that’s capable of feats long thought to be impossible.
The discovery, made by researchers from Germany, the Netherlands, and the US, overturns a century of thought on the nature of superconducting circuits, and how their currents can be tamed and put to practical use.
Low-waste, high-speed circuits based on the physics of superconductivity present a golden opportunity to take supercomputing technology to a whole new level.
Cybernetic Theory: Interpretive Model of Everything We Call the Universe
Another key insight of Cybernetic Theory can be referred to as “Mind Over Substrates”: Phenomenal “local” mind is “cybernetically” emergent from the underlying functional organization, whereas holistic “non-local” consciousness is transcendentally imminent. Material worlds come and go, but fundamental consciousness is ever-present, as the multiverse ontology is shown to be testable. From a new science of consciousness to simulation metaphysics, from evolutionary cybernetics to computational physics, from physics of time and information to quantum cosmology, this novel explanatory theory for a deeper understanding of reality is combined into one elegant theory of everything (ToE).
If you’re eager to familiarize with probably the most advanced ontological framework to date or if you’re already familiar with the Syntellect Hypothesis which, with this newly-released series, is now presented to you as the full-fledged Cybernetic Theory of Mind, then this 5-book set will surely present to you some newly-introduced and updated material if compared with the originally published version and can be read as a stand-alone work just like any book of the series:

Russia’s Attack on Ukraine is Making Everything on this Planet Worse
James McCall SpringerHmmm… So quantum computing systems aren’t close to being perfected BUT they’re being used for ransomware attacks?
Is “bleepingcomouter” a bs sensationalist media producer like Futurism?
Len Rosen shared a link.
The “special operation” as Russia calls it has come with a threat of nuclear war, and consequences for food and energy security for many.
Quantum ransomware seen deployed in rapid network attacks
The Quantum ransomware, a strain first discovered in August 2021, were seen carrying out speedy attacks that escalate quickly, leaving defenders little time to react.
The threat actors are using the IcedID malware as one of their initial access vectors, which deploys Cobalt Strike for remote access and leads to data theft and encryption using Quantum Locker.
The technical details of a Quantum ransomware attack were analyzed by security researchers at The DFIR Report, who says the attack lasted only 3 hours and 44 minutes from initial infection to the completion of encrypting devices.
Aliens Created Our Universe in a Lab, Scientist Suggests
If true, we started out as a “baby universe.” Cute.
Could our universe have been created in a petri dish? Avi Loeb seems to think so. The Harvard astronomer posits that a higher “class” of civilization may have conjured up our universe in a laboratory far, far away.
“Since our universe has a flat geometry with a zero net energy, an advanced civilization could have developed a technology that created a baby universe out of nothing through quantum tunneling,” Loeb writes in an op-ed published by Scientific American last year.
Scientists demonstrate the use of a hydrogen molecule as a quantum sensor
What if we could use a hydrogen molecule as a quantum sensor in a terahertz laser-equipped scanning tunneling microscope? This would allow us to measure the chemical properties of materials at unprecedented time and spatial resolutions.
This new technique has now been developed by physicists at the University of California, Irvine, according to a statement released by the institution on Friday.
“This project represents an advance in both the measurement technique and the scientific question the approach allowed us to explore,” said in the press release co-author of the new study Wilson Ho, Donald Bren Professor of physics & astronomy and chemistry.
PsiQuantum’s Path to 1 Million Qubits by the Middle of the Decade
PsiQuantum, founded in 2016 by four researchers with roots at Bristol University, Stanford University, and York University, is one of a few quantum computing startups that’s kept a moderately low PR profile. (That’s if you disregard the roughly $700 million in funding it has attracted.) The main reason is PsiQuantum has eschewed the clamorous public chase for NISQ (near-term intermediate scale quantum) computers and set out to develop a million-qubit system the company says will deliver big gains on big problems as soon as it arrives.
When will that be?
PsiQuantum says it will have all the manufacturing processes in place “by the middle of the decade” and it’s working closely with GlobalFoundries (GF) to turn its vision into reality. The generous size of its funding suggests many think it will succeed. PsiQuantum is betting on a photonics-based approach called fusion-based quantum computing (paper) that relies mostly on well-understood optical technology but requires extremely precise manufacturing tolerances to scale up. It also relies on managing individual photons, something that has proven difficult for others.
