I understand that we can create entangled particles in the lab. But how many (non-locally) entangled particles (such as photons/polarisation or electrons/spin) exist in free nature?

Very nice research. Coincidentally I was working on practically the similar thing today. However, as layman as layman can get. But I find this very nice. Thanks!Mentz114 said:Have a look at this. Someone obviously thinks entanglement is ubiquitous.

entropy1 said:If all or very many particles in the universe are entangled, does that mean that by measuring, say, a property of a particular particle, the properties of its entangled co-particles collapse into a different value (non-locally)?

No, but QM does require thinking about physical systems in an unfamiliar and more mathematically abstract way. You do have to form at least a qualitative understanding of what we're talking about when we say "operator" and "vector in Hilbert space" and how these concepts relate to the observable properties of stuff around us.entropy1 said:Do I really have to become a physicist to be able to understand some basic aspects of quantum mechanics?
- as Dr Henry P. Stapp said in "Mind, Matter and QM" : "How is quantum theory related to reality?" - according to him, it's the second of the "four basic questions concerning the nature of nature".Nugatory said:... and how these concepts relate to the observable properties of stuff around us.
When I said "... relate to the observable properties of stuff" I was deliberately using the wording I did to avoid bringing up this question about "reality". Many people (myself included) find that question interesting and important, but there is little point in taking it on until you understand how quantum theory works as a mathematical tool for predicting the results of observations.AlexCaledin said:"How is quantum theory related to reality?"

The number of entangled particles in nature refers to the number of particles that are connected or correlated in a quantum state, even if they are physically separated from each other.
It is impossible to accurately determine the exact number of entangled particles in nature as it is an ongoing and constantly changing phenomenon. However, it is estimated that there are trillions of entangled particles in the universe.
Scientists use various methods, such as quantum tomography and Bell tests, to detect and confirm the existence of entangled particles in nature. These methods involve measuring the properties of the particles and comparing them to determine if they are correlated.
Entangled particles have significant implications in quantum mechanics and have led to the development of technologies such as quantum computing and quantum cryptography. They also provide insights into the nature of reality and the interconnectedness of particles in the universe.
No, not all particles in nature are entangled. Entanglement is a unique property of quantum particles, and it is not a default state for all particles. Scientists are still studying the conditions and factors that lead to entanglement in nature.
