User talk:Shitikanth/sandbox/QIP (complexity)

Shitikanth,

I noticed several gaps in the narrative on this page:

- 'quantum interactive proof', 'strategy', 'no matter what the prover does' (what is the prover allowed to do?), 'completeness' and 'soundness' are not defined (a definition or a reference should be given here)

- the description of the proof system for quantum circuit distinguishability is incomplete at best

- the proof of statement (1): the description of the protocol is clipped, and the proof seems incomplete

- the proof of statement (2) is also incomplete

- a description of the steps in the QIP = PSPACE proof would be helpful

- much of the notation in the section on parallel approximation is undefined (Phi_1, Phi_2, theta, Psi, ...)

- the loss matrix in the MMWU algorithm should be defined ("observe the loss matrix..." is probably a vestige from the generic scheme)

- details on approximate calculation of the matrix operations and implementation in PSPACE is missing

- reference for Reichardt et al. is missing

- check for typos everywhere; there are quite a few
