QBism and the philosophical crisis of quantum mechanics

Posted by in categories: computing, cosmology, quantum physics

The famous Copenhagen Interpretation favored by the founders of quantum mechanics is most definitely psi-epistemic. Niels Bohr, Werner Heisenberg, and others saw the state vector as being related to our interactions with the Universe. As Bohr said, “Physics is not about how the world is; it is about what we can say about the world.”

QBism is also definitively psi-epistemic, but it is not the Copenhagen Interpretation. Its epistemic focus grew organically from its founders’ work in quantum information science, which is arguably the most important development in quantum studies over the last 30 years. As physicists began thinking about quantum computers, they recognized that seeing the quantum in terms of information — an idea with strong epistemic grounding — provided new and powerful insights. By taking the information perspective seriously and asking, “Whose information?” the founders of QBism began a fundamentally new line of inquiry that, in the end, doesn’t require science fiction ideas like infinite parallel universes. That to me is one of its great strengths.

But, like all quantum interpretations, there is a price to be paid by QBism for its psi-epistemic perspective. The perfectly accessible, perfectly knowable Universe of classical physics is gone forever, no matter what interpretation you choose. We’ll dive into the price of QBism next time.

AI is creating an alternative reality where even Tom Hanks can’t be trusted

Posted by in category: robotics/AI

Like Tom Hanks, victims of AI-generated trickery will need help getting out the message that they are not the ones who generated the content that’s being ascribed to them. The value of human expertise and decision-making in crisis management will become even more evident.

The AI revolution will have permanent repercussions beyond anything we can perhaps imagine today. Soon, organizations exploring and implementing the use of AI will invite unprecedented levels of risk.

Deepfake AI is now being used to create voice clones, convincing images and video hoaxes, all of which can be used to destroy an individual’s reputation or livelihood.

AI and Emerging Tech Challenges Call for Collaborative Solutions

Posted by in categories: cybercrime/malcode, policy, robotics/AI

Artificial intelligence (AI) and emerging technologies have ushered in a new era, bringing unprecedented opportunities and challenges. In today’s rapidly evolving digital landscape, addressing these multifaceted challenges necessitates a collaborative effort spanning various sectors and calls for policy reforms while emphasizing global cooperation.

The rapid advancement of technologies, particularly artificial intelligence, has introduced transformative possibilities alongside a range of concerns. While AI holds the potential to revolutionize industries and enhance our daily lives, it also raises pressing issues related to data privacy, misinformation, and cybersecurity.

Experts have proposed adopting the “information environment” framework to address these multifaceted challenges. This framework comprises three essential components:

Quantum Leap: Physicists Successfully Simulate Super Diffusion

Posted by in categories: computing, particle physics, quantum physics

Quantum physicists have simulated super diffusion in quantum particles on a quantum computer, paving the way for deeper insights into condensed matter physics and materials science. This achievement, realized on a 27-qubit system programmed remotely from Dublin, emphasizes the potential of quantum computing in both commercial and fundamental physics inquiries.

Quantum physicists at Trinity, working alongside IBM Dublin, have successfully simulated super diffusion in a system of interacting quantum particles on a quantum computer.

This is the first step in doing highly challenging quantum transport calculations on quantum hardware and, as the hardware improves over time, such work promises to shed new light in condensed matter physics and materials science.

‘Ring of fire’ eclipse Oct. 14 will be practice run for total solar eclipse next year

Posted by in category: space

Scientists generally, said NSF’s Lisa Winter, will be able to view a very active corona — or upper atmosphere of the sun — during the precious minutes that the sun is nearly completely blocked by the moon. The sun is nearing its maximum of solar activity in its 11-year-cycle, unlike the last U.S. total solar eclipse of 2017, meaning that “the corona will be very active this time around,” said Winter, who is NSF’s program director for solar-terrestrial research.

Solar activity has an immense impact on the ionosphere, which is a layer of Earth’s atmosphere that interacts with electromagnetic radiation from above and below its extent. These interactions affect the propagation of radio signals.

Neuroscientists’ long-term memory discovery might help dementia research

Posted by in categories: biotech/medical, neuroscience

Neuroscientists in New York have made a major breakthrough in memory research that promises to revolutionize our understanding of neurodegenerative diseases like Alzheimer’s.

A new study details how a structural cell that wraps around blood vessels may actually play an important role in the formation and storage of long-term memories.

According to the U.S Centers for Disease Control and Prevention, roughly 5.8 million American adults live with Alzheimer’s disease and other related dementias. And yet, our understanding of these diseases is still fairly limited, largely thanks to question marks over how memories are actually formed.

New research may make future design of nanotechnology safer with fewer side effects

Posted by in categories: biotech/medical, nanotechnology

A new study, published in Nature Nanotechnology, may offer a strategy that mitigates negative side effects associated with intravenous injection of nanoparticles commonly used in medicine.

“Nanotechnology’s main advantage over conventional medical treatments is its ability to more precisely target tissues, such as targeted by chemotherapy. However, when nanoparticles are injected, they can activate part of the called complement,” said senior author Dmitri Simberg, Ph.D., professor of Nanomedicine and Nanosafety at the University of Colorado Skaggs School of Pharmacy on the University of Colorado Anschutz Medical Campus.

Complement is a group of proteins in the immune system that recognize and neutralize bacteria and viruses, including nanoparticles which are foreign to the body. As a result, nanoparticles are attacked by triggering side effects that include shortness of breath, elevated heart rate, fever, hypotension, and, in rare cases, anaphylactic shock.

Natural genetically modified crops: Grasses take evolutionary shortcut by borrowing genes from their neighbors

Posted by in categories: biotech/medical, food, genetics

Grass may transfer genes from their neighbors in the same way genetically modified crops are made, a new study has revealed.

Research, led by the University of Sheffield, is the first to show the frequency at which grasses incorporate DNA from other species into their genomes through a process known as lateral gene transfer.

The stolen genetic secrets give them an by allowing them to grow faster, bigger or stronger and adapt to new environments quicker.

“The Universe Came From a Black Hole” String Theory Founder Reveals James Webb Telescope’s New Image. Deep within dense star clusters, something extraordinary dwells: Stars. But these, are no ordinary stars, but colossal celestial beings, known as supermassive stars. And now, their existence has been unveiled by the piercing gaze of the James Webb Space Telescope.

According to the standard model of cosmology, after the universe came out of the big bang, it took between 500 million to 1 billion years for the first stars to form. That however, is changing.
