Def. Let p>2p>2 be a prime number, then we will call quadratic residues all 1≤x≤p−11≤x≤p−1 modulo pp such that the equation a2≡x(modp)a2≡x(modp) has solutions and quadratic nonresidues otherwise. Note that 00 is neither quadratic residue nor quadratic nonresidue. Theorem...

We propose a quantum mechanical algorithm for solving quadratic residue equation z 2=b (mod M) based on Grover quantum search. The quantum algorithm will take O( ) steps for finding the solutions to the equation by exploiting the properties of quantum superposition and interference effect, while ...
We apply variational method to the perturbed nonlinear Schrdinger equation having quadratic-cubic form of nonlinearity, to study localized optical pulses. Super-Gaussian and super-sech solitons are used as envelopes for the trial function. Numerical simulations are presented for specific values of the ...
