Geometric picture behind quantum expanders I don't see how is this supposed to help. |

Heuristics for definitions of open and closed quantum dynamics "a measurement corresponding to an operator X=∑λλPλ is represented by ρ↦∑λPλρPλ" doesn't seem to be correct, i.e. post-measurement result is given by one of $P_{\lambda}\rho P_{\lambda}$ (plus normalization), for $\lambda$ chosen nondeterministically. |

Constructing a Hamiltonian (as a polynomial of $q_i$ and $p_i$) from its spectrum Are the coefficients in this polynomial supposed to be real, or integer...? (in the latter case, you only have countably many such polynomials and uncountably many possible spectra) If the coefficients are real, your polynomial would have to somehow encode a subset of $N$ in the coefficients, which might be difficult to do) An interesting question, BTW. |

What papers should everyone read? What's the purpose behind reading these original papers? |

What papers should everyone read? Griffiths' books are excellent, but I don't think this answer is particularly on topic in this thread. |

What papers should everyone read? OP specifically asks: "Please provide at least a sentence what is inside and why you consider it so worth reading." |

Convexity — reference request I'm not sure what you are asking for. The paper you mention does not use the concept of convexity in any intricate way. Maybe try checking John Watrous' lecture notes on quantum information theory: cs.uwaterloo.ca/~watrous/CS766 |

Possible research implications of proof of John Cardy's a-theorem in QFT More background? |

Quantum mechanics as a Markov process Hmm, this could be an interesting question, but can you provide more background and expand the question a little bit? |
