Scientists build ‘baby’ wormhole as sci-fi moves closer to fact

Posted by in categories: computing, cosmology, quantum physics, space travel

Year 2022 😗


WASHINGTON, Nov 30 (Reuters) — In science fiction — think films and TV like “Interstellar” and “Star Trek” — wormholes in the cosmos serve as portals through space and time for spacecraft to traverse unimaginable distances with ease. If only it were that simple.

Scientists have long pursued a deeper understanding of wormholes and now appear to be making progress. Researchers announced on Wednesday that they forged two miniscule simulated black holes — those extraordinarily dense celestial objects with gravity so powerful that not even light can escape — in a quantum computer and transmitted a message between them through what amounted to a tunnel in space-time.

Scientists figured out how to manipulate ‘quantum light’ for the first time in history

Posted by in categories: particle physics, quantum physics

Manipulating anything in the world of quantum physics is tricky, but now, scientists have managed to manipulate quantum light particles that have a strong relationship with each other. The breakthrough sounds a bit obscure, especially if you aren’t studying quantum mechanics yourself, but it’s a huge success that will be fundamental in how scientists study the quantum realm from here forward.

Quantum aspects of the brain-mind relationship: A hypothesis with supporting evidence

Posted by in categories: neuroscience, quantum physics

Abstract.

If all aspects of the mind-brain relationship were adequately explained by classical physics, then there would be no need to propose alternatives. But faced with possibly unresolvable puzzles like qualia and free will, other approaches are required. In alignment with a suggestion by Heisenberg in 1958, we propose a model whereby the world consists of two elements: Ontologically real Possibles that do not obey Aristotle’s law of the excluded middle, and ontologically real Actuals that do. Based on this view, which bears resemblance to von Neumann’s 1955 proposal (von Neumann, 1955), and more recently by Stapp and others (Stapp, 2007; Rosenblum and Kuttner, 2006), measurement that is registered by an observer’s mind converts Possibles into Actuals. This quantum-oriented approach raises the intriguing prospect that some aspects of mind may be quantum, and that mind may play an active role in the physical world. A body of empirical evidence supports these possibilities, strengthening our proposal that the mind-brain relationship may be partially quantum.

What would we expect with a Partially Quantum Mind-Body System?

Posted by in categories: mapping, neuroscience, quantum physics

One of the largest mysteries of science is that humans have conscious awareness of their complex subjective experiences – or what we call “qualia” – such as being aware of what it’s like to delight in the color of a flower, melt into the comfort of a bed, or to feel sharp pain. Why and how qualia could emerge from physical matter and be a part of the human experience is unknown, and this is called the ‘hard problem’ of consciousness. Related to qualia is the mystery of why humans feel like they have free will, or the ability to intentionally choose and execute actions.

The ‘easy’ problem of consciousness is mapping these mind states to brain states, such as identifying which brain regions are active during a certain experience, such as smelling a flower. Despite advances in classical physics and neuroscience, many aspects of the mind-brain relationship, such as qualia, remain unresolved. New theories of mind are required to address this perennial mystery.

In a new paper, we propose that some aspects of mind are quantum and can play an active role in the physical world, explaining some of the unexplainable.

Photosynthesis Further Explained Using Quantum Chemical Calculations

Posted by in categories: chemistry, energy, quantum physics

Photosynthesis is the process that plants, algae, and even certain species of bacteria use to convert sunlight into oxygen and chemical energy stored as sugar (aka gluclose). But what are the mechanisms behind one of nature’s most profound processes?

These are questions that a team of researchers led by the Ludwig Maximilian University of Munich (LMU) hope to answer as they used quantum chemical calculations to examine a photosynthesis protein complex known as photosystem I (PSI) in hopes of better understanding the complete process of photosynthesis and how plants are able to convert sunlight to energy, specifically pertaining to how chlorophylls and the reaction center play their roles in the process.

The best of both worlds: A new algorithm fuses quantum and classical information for high-quality imaging

Posted by in categories: computing, information science, quantum physics

Researchers from Colorado State University and the Colorado School of Mines have thought up a new computational imaging strategy that exploits the best of both the quantum and classical worlds. They developed an efficient and robust algorithm that fuses quantum and classical information for high-quality imaging. The results of their research were published Dec. 21 in Intelligent Computing.

Recently, the quantum properties of light have been exploited to enable super resolution microscopy. While quantum information brings new possibilities, it has its own set of limitations.

The researchers’ approach is based on classical and quantum correlation functions obtained from photon counts, which are collected from quantum emitters illuminated by spatiotemporally structured illumination. Photon counts are processed and converted into signals of increasing order, which contain increasing spatial frequency information. The higher spatial resolution information, however, suffers from a reduced signal-to-noise ratio at increasingly larger correlation orders.

Machine intelligence and humanity benefit from ‘spiral’ of mutual learning, says proponent of ‘cognitive physics’

Posted by in categories: quantum physics, robotics/AI

Deyi Li from the Chinese Association for Artificial Intelligence believes that humans and machines have a mutually beneficial relationship.

His paper on machine , which was published in Intelligent Computing, builds on five groundbreaking works by Schrödinger, the father of quantum mechanics, Turing, the father of artificial intelligence, and Wiener, the father of cybernetics.

Inspired by Schrödinger’s book “What is Life? The Physical Aspect of the Living Cell,” Li believes that can be considered living things. That is, like humans, they decrease the amount of entropy or disorder in their environment through their interactions with the world.

Team devises crystal-clear solution to quantum computing puzzle

Posted by in categories: computing, quantum physics, security

University of Texas at Dallas researchers have developed a new approach that addresses challenges in the field of quantum computing and has the potential to revolutionize computing, communications and electronic security.

To make solid-state qubits, the basic information unit for quantum computers, a defect must be inserted into the to control the spin states of electrons. Creating and positioning the defect, however, especially in the most commonly used solid material——poses a major challenge.

UT Dallas researchers found that making qubits from thin, two-dimensional sheets of crystals called (TMDs) instead of diamond can solve this problem. Led by Dr. Kyeongjae Cho, professor of materials science and engineering in the Erik Jonsson School of Engineering and Computer Science, the researchers published their findings online Dec. 6 in Nature Communications.
