The Quantum Frontier with Brian Greene and John Preskill
Quantum Computing: Foundations, Scaling Challenges, and Gravitational Links
Explore how the probabilistic nature and inescapable entanglement of quantum mechanics enable computational power far beyond classical limits, and discover how these insights are now resolving long-standing mysteries about spacetime and black holes.
Short Summary
- Quantum computation achieves power by leveraging the exponential complexity of describing highly entangled quantum systems, which overwhelms classical memory capacities.
- Realizing useful quantum computing requires Quantum Error Correction (QEC) to bridge the gap between noisy physical qubits (error $\approx 1/1,000$) and reliable logical qubits (target error $\approx 1/1,000,000,000,000$).
- Discovering the necessary mathematical structures for QEC and information scrambling has provided unexpected, powerful tools for studying quantum gravity and spacetime geometry.
This conversation with physicist John Preskill navigates the core concepts of quantum mechanics, assesses the current state and future hurdles of building quantum computers, and traces the profound, cross-disciplinary impact of quantum information science on fundamental physics like cosmology and black hole thermodynamics.

Brian Greene's interviews are consistently outstanding.
This is the kind of conversation I can go on for a long time with two honest, very well prepared people. A conversation where you can learn and understand the topic of the day. Thank you
Hearing about the frontiers of science from those exploring them is just fantastic. And Dr. Greene is very good at hosting the discussion. This and PBS Spacetime may be my favorite channels.
One of the most enjoyable conversations I can recall.
Great 👍👍👍❤❤❤ conversation
Love love love these conversations. It brings substance and structure to such profound topics to the masses and still allows humans (highly intelligent ones) to be, in their own sense, trapped in a quantum state. Thanks for all you and your teams hard work!
I stopped at 23:31 for now. It took me more than 23 minutes to finish, as I paused often to get some information from GPT. It’s a blessing to live in this era, everyone can be so close to the knowledge they’d like to explore!
Brian’s backdrop tells more stories than the entire shelf of books🥀
Simply brilliant. thank you very much mr Preskill, mr Greene and WSF
"to teach a class is the best thing to learn something". I love this statement from John 😊
