ER=EPR: Leonard Susskind's FAQ on Black Holes & Quantum Complexity

  • Thread starter MTd2
  • Start date
In summary, the ER=EPR theory, proposed by physicists Leonard Susskind and Juan Maldacena in 2013, suggests that entangled particles and black holes are connected through wormholes. This theory has implications for understanding quantum entanglement, the black hole information paradox, and the structure of the universe. While it has not been proven, it has gained support from the scientific community and could potentially challenge traditional theories in physics.

Entanglement is not Enough
Leonard Susskind
(Submitted on 3 Nov 2014)
This is the written version of a lecture given at KITP in Oct 2014 on Black Holes and quantum complexity. I've included (in boldface) various questions that came up during the lecture and discussions the following day, as well as the quantitative calculations that form the basis of the arguments.

It is odd that no one has acknowledged this post. I have Susskind's paper on my e-reader as an enlightening soporific and anodyne to the day's controversies. Thanks.
 

FAQ: ER=EPR: Leonard Susskind's FAQ on Black Holes & Quantum Complexity

1. What is the ER=EPR theory?

The ER=EPR theory is a conjecture proposed by physicists Leonard Susskind and Juan Maldacena in 2013. It suggests that entangled particles, or "ER" (Einstein-Rosen) bridges, are connected by "EPR" (Einstein-Podolsky-Rosen) wormholes, providing a possible explanation for the quantum entanglement phenomenon.

2. How does ER=EPR relate to black holes?

ER=EPR proposes that the same wormhole connections that exist between entangled particles also exist between black holes. This suggests that entangled particles and black holes are connected through a network of wormholes, allowing for the transfer of information and potentially solving the black hole information paradox.

3. What is the significance of ER=EPR in understanding quantum complexity?

ER=EPR suggests that the connections between entangled particles and black holes could also exist between other complex quantum systems, leading to the theory that these systems are linked through a "quantum web." This could have implications for our understanding of the underlying structure of the universe and the nature of quantum complexity.

4. Is ER=EPR a proven theory?

No, ER=EPR is still a conjecture and has not been proven. However, it has gained significant interest and support from the scientific community and is being further explored through ongoing research and experiments.

5. How does ER=EPR impact our current understanding of black holes and quantum mechanics?

ER=EPR challenges traditional theories and opens up new possibilities for understanding the connections between black holes, entangled particles, and the nature of quantum mechanics. If proven, it could have a significant impact on our understanding of the universe and the laws of physics.
