Generating Entanglement Through Measurements: A Time to Tear Down and a Time to Build

Entanglement is one of the primary features of quantum systems, which characterizes how one part of a system is independent of the remainder. To reveal entanglement, measurements can be conducted. However, in the quantum world, one cannot measure a system without affecting it. In many situations, measurements simply destroy the entanglement of interest. In this talk, Postdoctoral Scholar Zhu-Xi Luo (KITP and Harvard) will describe how to turn the game around: we design competing measurements to generate more entanglement, realizing exotic phases of matter that are potentially useful for robust quantum computation.
