MIT Physicist: Are We Trapped Inside a Black Hole?
Notas do episódio
In this episode, I talk with Seth Lloyd, MIT professor and one of the pioneers of quantum computing. We discuss how quantum computers work and why just a few hundred qubits could unlock computational capabilities far beyond those of conventional computers, whether quantum computers will be able to break modern encryption, and how they could accelerate the development of artificial intelligence.
We also explore whether it might be possible to simulate the entire Universe, why the Universe itself can be viewed as a quantum computer, whether the laws of physics allow time travel and sending information into the past, as well as black holes, quantum information, and the limits of our understanding of reality.
