On the Exact Evaluation of Certain Instances of the Potts Partition Function by Quantum Computers [PDF]

open access: yes, 2007
We present an efficient quantum algorithm for the exact evaluation of either the fully ferromagnetic or anti-ferromagnetic q-state Potts partition function Z for a family of graphs related to irreducible cyclic codes.

Complete Solving for Explicit Evaluation of Gauss Sums in the Index 2 Case

open access: yes, 2010
Let $p$ be a prime number, $q=p^f$ for some positive integer $f$, $N$ be a positive integer such that $\gcd(N,p)=1$, and let $\k$ be a primitive multiplicative character of order $N$ over finite field $\fq$.

A note on the sign (unit root) ambiguities of Gauss sums in index 2 and 4 cases

open access: yes, 2009
Recently, the explicit evaluation of Gauss sums in the index 2 and 4 cases have been given in several papers (see [2,3,7,8]). In the course of evaluation, the sigh (or unit root) ambiguities are unavoidably occurred.

The value distribution of incomplete Gauss sums

open access: yes, 2012
It is well known that the classical Gauss sum, normalized by the square-root number of terms, takes only finitely many values. If one restricts the range of summation to a subinterval, a much richer structure emerges.

On the arithmetic of a family of twisted constant elliptic curves

open access: yes, 2019
Let $\mathbb{F}_r$ be a finite field of characteristic $p>3$. For any power $q$ of $p$, consider the elliptic curve $E=E_{q,r}$ defined by $y^2=x^3 + t^q -t$ over $K=\mathbb{F}_r(t)$.

Abstract algebra, projective geometry and time encoding of quantum information

open access: yes, 2005
Algebraic geometrical concepts are playing an increasing role in quantum applications such as coding, cryptography, tomography and computing. We point out here the prominent role played by Galois fields viewed as cyclotomic extensions of the integers ...

On matrix elements for the quantized cat map modulo prime powers

open access: yes, 2008
The quantum cat map is a model for a quantum system with underlying chaotic dynamics. In this paper we study the matrix elements of smooth observables in this model, when taking arithmetic symmetries into account. We give explicit formulas for the matrix

Bounds for twisted symmetric square $L$-functions - III

open access: yes, 2012
Let $f$ be a newform, and let $\chi$ be a primitive character of conductor $q^{\ell}$. Assume that $q$ is an odd prime. In this paper we prove the subconvex bound $$ L(\t1/2,\Sym f\otimes\chi)\ll_{f,q,\varepsilon} q^{3\ell(1/4-1/36+\varepsilon)} $$ for ...

Computing Dirichlet character sums to a power-full modulus

open access: yes, 2014
The Postnikov character formula is used to express large portions of a Dirichlet character sum in terms of quadratic exponential sums. The quadratic sums are then computed using an analytic algorithm previously derived by the author.

Factorization of numbers with Gauss sums: I. Mathematical background

open access: yes, 2011
We use the periodicity properties of generalized Gauss sums to factor numbers. Moreover, we derive rules for finding the factors and illustrate this factorization scheme for various examples.
