What Is Entanglement Anyway?

Mar 18, 2015

Entanglement or non-separability is the core idea of quantum theory. It is a simple idea: the universe is not a bunch of independent parts, but is rather one entity that evolves through time as one entity. That’s it. The problem is that this means there’s no such thing as causation. This is very hard to wrap your head around. Quantum theory is extraordinarily accurate, and our knowing quantum theory is why we have things like cell phones and computers. But what is quantum theory, really? Why is entanglement its primary prediction? This talk will explain what quantum theory is. I will show that quantum theory has nothing to do with tiny particles, wave-function collapse, or Schroedinger’s cat. Quantum theory is about how observers obtain information about the world. It is, in particular, about how observers who have memories and use language obtain information about the world. It is, in other words, about how you and I interact with perfectly ordinary things like tables and chairs and each other. You will leave this talk with a new understanding of quantum theory, and a new appreciation for entanglement.

Chris Fields is an interdisciplinary information scientist interested in both the physics and the cognitive neuroscience underlying the human perception of objects as spatially and temporally bounded entities. His current research focuses on deriving quantum theory from classical information theory; he also works on cell-cell communication and cellular information processing, the role of the “unconscious mind” in creative problem solving, and early childhood development, particularly the etiology of autism-spectrum conditions. He and his wife, author and yoga teacher Alison Tinsley, recently published Meditation: If You’re Doing It, You’re Doing It Right, in which they explore the experience of meditation with meditators from many walks of life.

Dr. Fields has also been a volunteer firefighter, a visual artist, and a travel writer. He currently divides his time between Sonoma, CA and Caunes Minervois, a village in southwestern France.
