Solutions of modular bootstrap constraints from quantum codes
[article]
2020
arXiv
pre-print
This relation reduces modular invariance of the 2d CFT partition function to simple algebraic relations at the level of a multivariate polynomial characterizing the corresponding code. ...
Here we report a way to assign to a particular family of quantum error correcting codes a family of "code CFTs" -- a subset in the space of Narain CFTs. ...
There are also many polynomials obeying the standard symmetries and constraints of the enumerator polynomial, which are nevertheless not enumerator polynomials of any actual code. ...

Parallel Shortest Lattice Vector Enumeration on Graphics Cards
[chapter]
2010
Lecture Notes in Computer Science
Our implementation is almost 5 times faster in high lattice dimensions. Exhaustive search is one of the main building blocks for lattice basis reduction in cryptanalysis. ...
In this paper we present an algorithm for parallel exhaustive search for short vectors in lattices. This algorithm can be applied to a wide range of parallel computing systems. ...
