Hyperbolic tesselation code

Hyperbolic tesselation code[1]

Description

Homogeneous-space code whose codewords are superpositions of positional delta functions on the hyperbolic phane. The positions are chosen according to certain planar tessellations. Tesselation code projections are onto a copy of an irreducible representation of the rotational symmetry group of the corresponding tessellation, known as the proper triangle group. The symmetry of the tesselation determines the easily implementable logical gate sets of this code.

Examples are the code constructed using the \(\{4,3,5\}\) tesselation realizing the binary icosahedral group \(2I\), the code constructed using the \(\{5,5,5\}\) tesselation realizing the modular-qudit Pauli group of 5-dimensional qudit, and the code constructed using the \(\{4,6,5\}\) tesselation realizing the single-qubit Clifford group \(2O\) [1].

Protection

Protects against sufficiently small shifts in position and momentum errors on the hyperbolic plane. Momentum errors are represented by LaPlacian eigenfunctions and are indexed by a continuous variable [1].

Gates

The logical operation of the codes are realized by rotations around certain points on the hyperbolic plane. If the hyperbolic plane is viewed as embedded in three dimensional space, the logical operations are implemented by Gaussian operations.

Cousins

Hyperbolic sphere packing— Hyperbolic tesselation codes are quantum counterparts of hyperbolic sphere packings because they store information in quantum superpositions of points on the hyperbolic plane.
Pauli tesselation QSC— Tesselation codes are constructed using symmetry groups of tesselations of real, spherical, and hyperbolic spaces [1]. Examples include the qutrit-Pauli tesselation code, Pauli tesselation QSC, and hyperbolic tesselation code, respectively.
Qutrit-Pauli tesselation code— Tesselation codes are constructed using symmetry groups of tesselations of real, spherical, and hyperbolic spaces [1]. Examples include the qutrit-Pauli tesselation code, Pauli tesselation QSC, and hyperbolic tesselation code, respectively.
