“This has been a scientific goal for 20 years, so it’s a very exciting era.”
In a significant advance, scientists have obtained the first proof of a phenomenon known as “quantum superchemistry.” This effect was previously predicted but never actually observed in the laboratory.
The University of Chicago researchers that led this experiment characterize quantum superchemistry as a “phenomenon where particles in the same quantum state undergo collectively accelerated reactions.”

Are quantum events required for consciousness in a very special sense, far beyond the general sense that quantum events are part of all physical systems? What would it take for quantum events, on such a micro-scale, to be relevant for brain function, which operates at the much higher level of neurons and brain circuits? What would it mean?

Just as carbon makes up both the brittle core of a No. 2 pencil and the harder-than-steel diamond in a cutting tool, boron nitride gives rise to compounds that can be soft or hard. Yet, unlike carbon, far less is known about boron nitride’s forms and their responses to changing temperatures and pressures.
Rice University scientists mixed hexagonal boron nitride —a soft variety also known as “white graphite”—with cubic boron nitride—a material second to diamond in hardness—and found that the resulting nanocomposite interacted with light and heat in unexpected ways that could be useful in next-generation microchips, quantum devices and other advanced technology applications.
“Hexagonal boron nitride is widely used in a variety of products, such as coatings, lubricants and cosmetics,” said Abhijit Biswas, a research scientist who is the lead author of a study about the research published in Nano Letters. “It’s quite soft and it is a great lubricant, and very lightweight. It’s also cheap and very stable at room temperature and under atmospheric pressure.
A team from the University of Chicago has announced the first evidence for “quantum superchemistry”—a phenomenon where particles in the same quantum state undergo collective accelerated reactions. The effect had been predicted, but never observed in the laboratory.
The write in their paper on the invention: “The LK-99 has many possibilities for various applications such as magnet, motor, cable, levitation train, power cable, qubit for a quantum computer, THz Antennas, etc. We believe that our new development will be a brand-new historical event that opens a new era for humankind.”
It’s important to note that while room-temperature superconducting advances may clear some of the scalability hurdles, warm temperatures still impact quantum errors.
That being said, and while scientists are still trying to verify this work, how will it affect quantum computing? If at all?
Collaboration yields new solutions that tackle complex challenges in defense and aerospace sectors
Companies to showcase live demonstration of quantum-hybrid application at Space & Missile Defense Symposium
BURNABY, British Columbia, PALO ALTO, Calif. & HUNTSVILLE, Ala., August 7, 2023 —(BUSINESS WIRE)— D-Wave Quantum Inc. (NYSE: QBTS), a leader in quantum computing systems, software, and services, and Davidson Technologies, Inc., a technology services company that provides innovative engineering, technical and management solutions for the Department of Defense, aerospace and commercial customers, today announced progress in their collaboration to create solutions that advance national defense efforts. In support of the companies’ joint presence at this week’s Space and Missile Defense Symposium, D-Wave and Davidson Technologies revealed that together they have built two applications, focused on interceptor assignment and optimized radar scheduling.
“I view string theory as the most promising way to quantize matter and gravity in a unified way. We need both quantum gravity and we need unification and a quantization of gravity. One of the reasons why string theory is promising is that there are no singularities associated with those singularities are the same type that they offer point particles.” — Robert Brandenberger.
In this thought-provoking conversation, my grad school mentor, Robert Brandenberger shares his unique perspective on various cosmological concepts. He challenges the notion of the fundamental nature of the Planck length, questioning its significance and delving into intriguing debates surrounding its importance in our understanding of the universe. He also addresses some eyebrow-raising claims made by Elon Musk about the limitations imposed by the Planck scale on the number of digits of pi.
Moving on to the topic of inflation and its potential detectability, Robert sheds light on the elusive B mode fluctuations and the role they play in understanding the flaws of general relativity. He explains why detecting these perturbations at the required scale may be beyond our current technological capabilities. The discussion further explores the motivations behind the search for cosmic strings in the microwave sky and the implications they hold for particle physics models beyond the standard model.
With his expertise in gravity and the quantization of mass, Robert Brandenberger emphasizes the need for a quantum mechanical approach to gravity. He discusses the emergence of time, space, and a metric from matrix models, offering new insights into the foundations of our understanding of the universe. The speaker’s work challenges conventional notions of inflation and proposes alternative models, such as string gas cosmology, as potential solutions.
Beyond the scientific aspects, Robert Brandenberger reflects on his role as a scientist and educator. He expresses his gratitude to a mentor and shares advice he received about navigating the academic world. Additionally, he discusses the evolution of being a professor over the past three decades and shares his thoughts on the profession as a whole.
This episode leaves us with many questions, tantalizing possibilities, and a deeper appreciation for the mysteries of the cosmos. We invite you to join us in this cosmic journey as we explore the frontiers of theoretical cosmology.
