Özet:
In the present thesis, we study superposition of coherent states as the kaleidoscope of quantum coherent states, associated with regular n-polygon symmetry and the roots of unity q2n = 1. These states are generalizations of the Schrödinger cat states, corresponding to the roots of unity q2 = −1. To describe physical characteristics of kaleidoscope states, we introduce new type of mod n exponential functions as a superposition of exponential functions in the form of discrete Fourier transform. These functions are also known as generalized hyperbolic functions, satisfying ordinary differential equations with proper initial conditions. Kaleidoscope states are eigenstates of n-th order eigenvalue problem for annihilation operator and are not minimal uncertainty states. These states are described as quantum Fourier transform of Glauber coherent states. Normalization factors, uncertainty relations, average number of photons and coordinate representation for these states are found in a compact form by mod n exponential functions. The set of kaleidoscope states, as orthonormal computatitonal basis of quantum states, describes generic qudit unit of quantum information. Relations of kaleidoscope states with quantum group symmetry are discussed. The special cases of trinity and quartet states, corresponding to qutrit and ququat units of quantum information are treated in details.
