1. Quantum II (PHYS 4410) Lecture 7 Quantum teleportation then, Begin treatment of “impossible” problems Homework sessions are now Monday 4-6P here. HWK 2 is due today at 5PM.

2. Physics Colloquium 4PM today, Duane G1B20 Prof. Rob Schoelkopf, Yale University The Birth, Care, and Feeding of Cat States in Circuit QED: Quantum Jumps of Photon Parity

4. 150 A) TRUE B) FALSE TRUE or FALSE: In the end, a quantum system is always found in one or another of the energy eigenstates.

5. 150 A) TRUE B) FALSE TRUE or FALSE: Before your can discuss the quantum mechanics of some particular system, you must know the Hamiltonian.

6. 150 Why do we worry so much about the Hamiltonian?? Time dependence of state vectors. Thoughts? It is an observable. Provides orthonormal basis set like all Hermitian operators.
