The toric code
WebAug 8, 2024 · The toric code is an example of a topological state of matter. A state of matter, or phase, cannot become a different phase without some discontinuity in the physical properties as coefficients in the Hamiltonian change. This discontinuity may exist in an arbitrary order derivative or non-local observable. WebThe toric code is fairly symmetric between the vertex and plaquette terms. Clearly, focusing on the \(\sigma_z\) diagonal basis was a choice. If we draw loops (blue lines) through the …

WebJan 18, 2024 · Toric code Hamiltonian. The toric code Hamiltonian \begin{equation} H = -\sum_s A_s - \sum_p B_p \end{equation} involves local four-qubit parity operators, where each qubit lives on an edge in a square lattice. WebSep 2, 2024 · In the present work we consider Kitaev’s toric code[22,23,25] which is a stabilizer code formulated on a square lattice with periodic boundary conditions (see Figure1and Section2.1). We will only consider bit-ip errors which correspond to syndromes with one type of violated stabilizer that can be represented as plaquette
WebDec 11, 2024 · A bstract. It was well known that there are e -particles and m -strings in the 3-dimensional (spatial dimension) toric code model, which realizes the 3-dimensional ℤ 2 topological order. Recent mathematical result, however, shows that there are additional string-like topological defects in the 3-dimensional ℤ 2 topological order.
