Quantum entanglement between distant large objects

 

Entanglement is a link between two sister particles or objects, making them behave as a single entity. Researchers at the Niels Bohr Institute, University of Copenhagen, entangled a mechanical oscillator—a vibrating dielectric membrane—with an atom cloud's spin (magnetic orientation).  These very different entities were possible to entangle by connecting them with photons, particles of light. Atoms can be useful in processing quantum information, and the membrane—or mechanical quantum systems in general—can be useful for the storage of quantum information.

Professor Eugene Polzik, who led the effort, states that: "With this new technique, we are on route to pushing the boundaries of the possibilities of entanglement. The bigger the objects, the further apart they are, . . . the more interesting entanglement becomes from both fundamental and applied perspectives. With the new result, entanglement between very different objects has become possible."

The experiment might be a step towards limitless precision of measurements of motion.

The work, "Entanglement between distant macroscopic mechanical and spin systems" was published in Nature Physics.

Cognitive phenomena show quantum, particle-like features

Animals gather nutrients and avoid physical dangers; they actively enhance their access to information and thus their survival through the sensory system. Because sensory organs are information-gathering machines, interaction with sensory stimuli corresponds to an energy-information exchange. 

The subtle regulation of brain frequencies' path, rhythm, and extent makes the brain a complex yet ingenious system. However, the brain is much more than a finely regulated circuit board. Electrical activity generates associations, meaning, and memory in ways reminiscent of quantum networks. Quantum theory has modeled mental phenomena in fields as diverse as search engine optimization, psychology, economics, and sociology for nearly a century. More than 70 recent national surveys examined the order effect of successive attitude questions and found that human judgment aligns with quantum probability theory. In quantum systems, outcomes depend heavily on the measurement context; likewise, almost all cognitive processes, such as memory, decisions, and perception, are contextual. In social science, quantum theory can predict how question order affects outcomes.

The cortex's pattern of neuronal activation triggers corresponding memories or experiences and forms a "temporal horizon." Reminiscent of the observer effect in quantum mechanics, the brain's quantum-like evolution maintains the mind's unity and permanence. Measurement (interaction) actively changes the particle being measured, and in the brain, this corresponds to cognitive change. The mental world is organized into a steady, stepwise progression of perception or learning, such as the empowering moment of riding a bike for the first time. The same holds for recognition, getting a joke, or meeting a friend. A moment of inspiration occurs when a new balance forms and understanding clicks. Conscious awareness holds mental content "fixed" and "frozen" within a discrete yet continuous phenomenal unity. Because sensory processing converts spatial relationships into temporal rhythms, the material world's spatial relationships translate into temporal evolution. 

The brain's gradually improving responses to stimuli shaped the mind into a structural, organizational mirror of physical systems. Therefore, social interaction engenders particle-like features and quantum characteristics, such as uncertainty, hysteresis, and territorial needs.

Quantum entanglement is characteristic of the mind

In the material world, apparent randomness often conceals the underlying determinism. The fusion of predictability with the unexpected creates a fractal structure in nature. Surprisingly, the temporal rhythm of mental phenomena also represents a fractal structure. The mind forms resonance and interference, indicating that cognitive processes obey the laws of quantum mechanics. Therefore, a social laser can model social unrest as a coherent energy transmission.

Entanglement is a phenomenon in which changes in one part of the system instantaneously influence the state of another part, even across large distances. Applying entanglement in a cognitive context can model emotional behavior. For example, entanglement activates associative target words simultaneously. In the social context, social entanglement refers to a perceived power difference in human interaction. It leads to domination, empowering one partner and subjugating the other. Thus, social entanglement plays a role in shaping social structure.  

One person can even create an entanglement between two separate events! When two events are separated in time, nonlocality encompasses fictional time travel to the past. This recollection updates comprehension by pushing understanding into the past and the future. This timelessness indicates that understanding can be influenced by significant temporal spans. In this way, childhood memories transform into adult understanding within an adult's mind. 

Similar to the quantum mechanic's particle experiment, new information can entirely overturn a solidified mental reality. When we uncover a secret, our comprehension expands to the past, envisioning the time of the first experience. Ideas in the hidden corners of the mind can be reshaped by information years or even decades later. For instance, sexual harassment and abuse are demeaning and degrading for the victim. However, even years later, a new understanding can reverse the relationship dynamics and empower the victim. Often, revealing or constructively processing past abuses, victims of sexual or social misconduct experience healing and liberation. 

We have more power over our personal history than we realize. By creating a positive meaning for the past, we give rise to a better future.
