Return a JIT‑compiled BP decoder for the given code and channel. Parameters ---------- parity_check_matrix : array‑like (m, n) e

Given an algebra g and an operator subspace k, verify that k is a subalgebra and gives rise to a Cartan decomposition. Similar to qp.liealg.check_

Apply an operation in a brickwall-like pattern to a qubit register and measure H. Parameters are assumed to have the dimensions (number of blocks

Circuit used to derive a0

Compute how many circuit evaluations one needs for kernel-based training and prediction.

Prints a Clifford Tableau representation for a given operation.

Sends |c>|x>|0> to |c>|ax mod N>|0> if c = 1. The mask arguments allow for the removal of unnecessary double-controlled additions.

Cost function to be minimized. Args: params (array[float]): array of parameters x (array[float]): 2-d array of input vectors

Returns a random undirected adjacency matrix of dimension (n,n). The diagonal elements are interpreted as node attributes.
