Nov 10 Some more math (Dirac's bra/ket notation, tensors), Quantum teleporation, measurements in other bases, superdense coding
Nov 17 EPR and Bell inequalities, simulating classical circuit by quantum circuits, effects of garbage, Deutsch's algorithm
Nov 24 The Fourier transform over Z_2^n, Deutsch-Jozsa algorithm, Bernstein-Vazirani algorithm, Simon's algorithm

Feb 2 The singular value decomposition. Schmidt decomposition. Purifications. Fidelity.
Mar 5 Fidelity and other distance measures, relations among them. Bit commitement.

May 7 QMA-complete problems
May 14 QMA-complete problems
May 21 Perfect completeness for IP[k]. Perfect completeness for QIP[k] for k >2.
May 28 MA is in AM. QIP = QIP[3]
Jun 4 Super-operators, l_1 norm for super-operators, diamond norm, characterizing the acceptance probability of QIP[3] by the diamond norm of a super-operator determined by the verifier's actions
Jun 11 Amplificiation of QIP[3], QIP is in EXP
