Physics 213/113, Winter 2023: Quantum Information is Physical.
The subject of the course is ideas from information theory which have been or may be useful
for quantum many body physics.
Here is a slightly longer description of my current plan:
The course will include a primer on Shannon's theory
on the compression and transmission of information,
and its extensions to quantum systems.
Applications to manybody physics incorporate
the consequences of locality, which include
 the ubiquitous area law for the entanglement entropy
of subsystems in lowenergy states,
 constraints on the dynamics of quantum field theories,
and
 the ideas about tensor networks which underlie stateoftheart numerical methods.
The final section of the course will explore the deep connections
between faulttolerant quantum computers and
highlyentangled (spin liquid) phases of matter.
The target audience includes
students working on high energy physics, condensed matter physics (soft and hard) and astrophysics,
both theorists and experimenters, as well as ambitious undergrads with some familiarity with quantum mechanics.
The website for a previous incarnation of the course is
