Witt Groups and Bulk-Boundary Correspondence for Stabilizer States
BÅażej Ruba, Bowen Yang
We establish a bulk--boundary correspondence for translation-invariant stabilizer states in arbitrary spatial dimension, formulated in the framework of modules over Laurent polynom…
Optimal Remainder Estimates in the Quantization of Complex Projective Spaces
Tommaso Aschieri, BÅażej Ruba, Jan Philip Solovej
We study Berezin-Toeplitz quantization of complex projective spaces and obtain full asymptotic expansions of the Berezin transformation and of products of Toepl…
Point potentials on Euclidean space, hyperbolic space and sphere in any dimension
Jan DereziÅski, Christian GaÃ, BÅażej Ruba
In dimensions d= 1, 2, 3 the Laplacian can be perturbed by a point potential. In higher dimensions the Laplacian with a point potential cannot be defined as a self-adjoint operator…
Homological invariants of Pauli stabilizer codes
Blazej Ruba, Bowen Yang
We study translationally invariant Pauli stabilizer codes with qudits of arbitrary, not necessarily uniform, dimensions. Using homological methods, we define a series of invariants…
