  • Picture-Languages for Quantum Information I

    Speaker: Carl Miller (University of Maryland, College Park) - http://www.umiacs.umd.edu/~camiller/

    When: Mon, October 2, 2017 - 4:15pm
    Where: Atlantic 3100A

    Abstract: The conventional way to express proofs in quantum information is via vector spaces and linear operators. I will discuss a newer, intuitive approach which is based on local manipulations of box-and-wire diagrams. The first talk will introduce picture elements for some basic concepts (registers, states, processes). The primary references for this material are arXiv:1510.05468, arXiv:1605.08617, and the book Picturing Quantum Processes by B. Coecke and A. Kissinger.

    Abstract: I will continue with an introduction to proofs-by-picture in quantum information, and discuss some directions for further development.
  • Quantum Strategy Formalism I

    Speaker: Yuan Su (University of Maryland) -

    When: Mon, October 16, 2017 - 4:15pm
    Where: Atlantic 3100A

    View Abstract

    Abstract: This talk will focus on the quantum strategy formalism proposed by Gus Gutoski and John Watrous. In this new formalism, the strategy of each participant in any multi-party interaction is associated with a positive semidefinite operator, and the interaction output probability is given by the inner product of two such operators. The first part of the talk discusses basic notions of quantum strategy formalism, with occasional detour to quantum information preliminaries.

In this new formalism, the strategy of each participant in any multi-party interaction is associated with a positive semidefinite operator, and the interaction output probability is given by the inner product of two such operators. The second part of the talk presents a characterization of strategies in terms of linear constraints on positive semidefinite operators, with occasional detour to quantum information preliminaries.
