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 many-body physics incorporate
the consequences of locality, which include
-- the ubiquitous area law for the entanglement entropy
of subsystems in low-energy states,
-- constraints on the dynamics of quantum field theories,
and
-- the ideas about tensor networks which underlie state-of-the-art numerical methods.
The final section of the course will explore the deep connections
between fault-tolerant quantum computers and
highly-entangled (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
here.
