Hi all,
a reminder of Beni Yoshida's talk today at 4 pm in the Time Room.
Title: Exotic topological order from quantum fractal code
Speaker: Beni Yoshida (MIT and Caltech)
Abstract:
We present a family of three-dimensional local quantum codes with
pairs of fractal logical operators. It has two polynomials over
finite fields as input parameters which generate fractal shapes of
anti-commuting logical operators, and possesses exotic topological
order with quantum glassiness which is beyond descriptions of
conventional topological field theory. A necessary and sufficient
condition for being free from string-like logical operators is
obtained under which the model works as marginally self-correcting
quantum memory. We also provide theoretical tools to analyze
physical and coding properties of translation symmetric stabilizer
Hamiltonians.
