Starting today: Kazhdan Sunday seminar: “Computation, quantumness, symplectic geometry, and information”

Sunday, 27 October, 2019 – 14:00 to 16:00

Repeats every week every Sunday until Sat Feb 01 2020

Location: Ross 70

See also: Seminar announcement; previous post Symplectic Geometry, Quantization, and Quantum Noise.

The Google supremacy claims are discussed (with updates from time to time) in this earlier post. Don’t miss our previous post on combinatorics.

Tentative syllabus for “Computation, quantumness, symplectic geometry, and information”

1. Mathematical models of classical and quantum mechanics.

2. Correspondence principle and quantization.

3. Classical and quantum computation: gates, circuits, algorithms (Shor, Grover). Solovay-Kitaev. Some ideas of cryptography

4. Quantum noise and measurement, and rigidity of the Poisson bracket.

5. Noisy classical and quantum computing and error correction, threshold theorem- quantum fault tolerance (small noise is good for quantum computation). Kitaev’s surface code.

6. Quantum speed limit/time-energy uncertainty vs symplectic displacement energy.

7. Time-energy uncertainty and quantum computation (Dorit or her student?)

8. Berezin transform, Markov chains, spectral gap, noise.

9. Adiabatic computation, quantum PCP (probabilistically checkable proofs) conjecture [? under discussion]

10. Noise stability and noise sensitivity of Boolean functions, noisy boson sampling

11. Connection to quantum field theory (Guy?).
