All Abstracts | Poster Abstracts | Talk Abstracts | Tutorial Abstracts 1. Convexity and Positivity in Quantum Information: Part IHoward Barnum, Los Alamos National Laboratory (Session 101 : Thursday from 16:00-18:00) Abstract. Convex sets and convex cones occur frequently in quantum
information theory. For example, normalized density matrices, completely
positive maps, separable states, and POVMs all form convex sets. Finding an
optimal quantum information processing protocol can often be cast as
minimizing a linear function over a compact convex set, a problem for which
much is known. This tutorial will cover some of the basic theory of convex
sets and optimization over them, and applications to quantum information
processing.
2. Convexity and Positivity in Quantum Information: Part IIAndrew Landahl, University of New Mexico (Session 101 : Thursday from 16:00-18:00) Abstract. Convex sets and convex cones occur frequently in quantum information theory. For example, normalized density matrices, completely positive maps, separable states, and POVMs all form convex sets. Finding an optimal quantum information processing protocol can often be cast as minimizing a linear function over a compact convex set, a problem for which much is known.

3. Beyond T1: Measuring Coherence with State and Process TomographyJohn Martinis, University of California, Santa Barbara (Session 101 : Thursday from 13:30-15:30) Abstract. The tutorial would review the physics and mathematics behind the metrology of qubit coherence, using specific examples from recent experiments on superconducting qubits.
4. Entanglement and VerificationSteven van Enk, University of Oregon (Session 101 : Thursday from 10:00-12:00) Abstract. Besides giving a general and simple introduction to bipartite entanglement,
the main idea of the tutorial is to illustrate the differences between the
theory and practice of entanglement verification.
