Construction of quantum BCH code based on cyclotomic coset

open access: yesTongxin xuebao, 2021
Quantum-error-correcting code can overcome quantum decoherence efficiently, which is the key technology to realize quantum computers.A series of quantum BCH code was proposed based on classical codes.First, a general way of well-chosen cyclotomic coset ...

On cyclotomic elements and cyclotomic subgroups in $K_{2}$ of a field [PDF]

open access: yesActa Arithmetica, 2016
The problem of expressing an element of K_2(F) in a more explicit form gives rise to many works. To avoid a restrictive condition in a work of Tate, Browkin considered cyclotomic elements as the candidate for the element with an explicit form. In this paper, we modify and change Browkin's conjecture about cyclotomic elements into more precise forms, in

The Class Number of the Cyclotomic Field [PDF]

open access: yesProceedings of the National Academy of Sciences, 1949
Let g denote an odd prime, and h = h(g) the class number of the cyclotomic field R(), where is a primitive gth root of unity. It is known that we can write

Frequency-Hopping Sequences With Optimal Average Hamming Correlation and Their Applications in Energy and Spectrum Harvesting Technologies Area

open access: yesIEEE Access, 2021
The research of cyclotomy theory can be traced to Gauss and it has been applied to many fields such as cryptography, coding theory, and combinatorics. According to $v$ prime numbers or compound words, the incision on the residue-like ring ${\mathbb Z ...

Cyclotomic splitting fields [PDF]

open access: yesProceedings of the American Mathematical Society, 1970
Suppose k is an algebraic nunmber field and D a finite- dimensional central division algebra over k. It is well known that D has infinitely many maximal subfields which are cyclic exten- sions of k. From the point of view of group representations, how- ever, the natural splitting fields are the cyclotomnic ones.

ON WEIL NUMBERS IN CYCLOTOMIC FIELDS [PDF]

open access: yesInternational Journal of Number Theory, 2009
In this paper, we study the p-adic behavior of Weil numbers in the cyclotomic ℤp-extension of the pth cyclotomic field. We determine the characteristic ideal of the quotient of semi-local units by Weil numbers in terms of the characteristic ideals of some classical modules that appear in the Iwasawa theory.

Efficient Algorithm for Finding Roots of Error-Locator Polynomials

open access: yesIEEE Access, 2021
A novel method for finding roots of polynomials over finite fields has been proposed. This method is based on the cyclotomic discrete Fourier transform algorithm. The improvement is achieved by using the normalized cyclic convolutions, which have a small

New Constructions for Near-Optimal Sets of Frequency-Hopping Sequences via the Gaussian Periods in Finite Fields

open access: yesIEEE Access, 2022
Frequency-hopping sequences (FHSs) have been widely applied in frequency-hopping code-division multiple-access (FH-CDMA) systems, since they can be used for transmitting messages efficiently along with switching frequencies at set intervals by each ...
