This paper has been withdrawn by the authors, due a oversimplified decoherence model. It will be substituted by a new work.

In the frame of our approach we constructed the generalized oscillator connected with Krawtchouk polynomials (named Krawtchouk oscillator) and coherent states for this oscillator too. Ours results are compared with analogues ones obtained…

This paper has been withdrawn by the author due to a crucial error related with the consideration of regular points

The notions of qubits and coherent states correspond to different physical systems and are described by specific formalisms. Qubits are associated with a two-dimensional Hilbert space and can be illustrated on the Bloch sphere. In contrast,…

Quantum no-cloning, the impossibility of perfectly cloning an arbitrary unknown quantum state, is one of the most fundamental limitations due to the laws of quantum mechanics, which underpin the physical security of quantum key…

This paper has been withdrawn due to a crucial theoretical error.

The inability to produce two perfect copies of an unknown state is inherently linked with the inability to produce maximal entanglement between multiple spins. Despite this, there is no quantitative link between how much entanglement can be…

This paper has been withdrawn by the author due to some problems.

The paper has been withdrawn by the author due to unhappy mistake in the initial scope of the work.

This paper has been withdrawn by the author due to a crucial error in eq.59. I apologize for the inconveniences.

The investigation of the generalized coherent states for oscillator-like systems connected with given family of orthogonal polynomials is continued. In this work we consider oscillators connected with Meixner and Meixner-Pollaczek…

This paper has been withdrawn by the authors due to a critical error discovered in Figures 1, 2 and 4.

We propose two feasible experimental implementations of an optimal asymmetric 1->2 quantum cloning of a polarization state of photon. Both implementations are based on a partial and optimal reverse of recent conditional symmetrical quantum…

We withdraw our paper as the factorizability of the correlation functions is unproven.
