- Abstract: We present a discussion of the generalized Clifford group over non-cyclic
finite abelian groups. These Clifford groups appear naturally in the theory of
topological error correction and abelian anyon models. We demonstrate a
generalized Gottesman-Knill theorem, stating that every Clifford circuit can be
efficiently classically simulated. We additionally provide circuits for a
universal quantum computing scheme based on local two-qudit Clifford gates and
magic states.

Clifford circuits can be utilized to disentangle quantum state with cost, thanks to the Gottesman-Knill theorem.
Based on this idea, Clifford Circuits Augmented Matrix Product States ( CAMPS) was proposed recently and was shown to be able to reduce entanglement in various quantum systems.
In this work, we explore the power of CAMPS method in critical spin chains described by conformal field theories (CFTs) in the scaling limit.

We study simulability of marginals as well as Pauli expectation values of Clifford and matchgate hybrid circuits.
Most importantly, we show that the known simulability of Pauli expectation values of Clifford circuits acting on product states can be generalized to Clifford circuits acting after any matchgate circuit.

We study Clifford quantum circuits acting on $mathsfd$-dimensional lattices of prime $p$-dimensional qudits.
We calculate homotopy classes of such loops for any odd $p$ and $mathsfd=0,1,2,3$, and $4$.
We observe that the homotopy classes of loops of Clifford circuits in $(mathsfd+1)$-dimensions coincide with the quotient of the group of Clifford Quantum Cellular Automata modulo shallow circuits and lattice translations in $mathsfd$-dimensions

Groups [18.6870237776672]
Crystallographic groups describe the symmetries of crystals and other repetitive structures encountered in nature and the sciences.
We derive linear and nonlinear representations of functions that are (1) smooth and (2) invariant under such a group.
We show that such a basis exists for each crystallographic group, that it is orthonormal in the relevant $L$ space, and recover the standard Fourier basis as a special case for pure shift groups.
