MULTICLONES QUANTUM CLONING OF QUTRITS

International Journal of Quantum Information, 2010
In this paper, we present the explicit transformations of the optimal 1 → 3 universal quantum and the phase-covariant cloning in 3 dimensions (qutrits). The fidelities of two types of cloners reach the theoretical bounds.

Quantum Router for Qutrit Networks

2020
Networks of quantum circuits or, more generally, networks transmitting quantum information will need, just like classical networks (e.g. internet), a mechanism for directing data to adequate nodes. Routing, understood as packet switching, is one of the most important processes in classical networks.

A Qutrit Switch for Quantum Networks

2017
The chapter contains information about a construction of quantum switch for qutrits. It is an expansion of the idea of quantum switch for qubits. For the networks based on quantum effects the switch could realize an operation of changing the direction of transferred information.

Distributed qutrit–qutrit entanglement via quantum Zeno dynamics

Optics Communications, 2011
Abstract A scheme is proposed to generate a three-dimensional entangled state for two atoms trapped in two distant cavities via quantum Zeno dynamics. We study such system in the regime of resonant atom–field interactions, which makes the scheme work very fast.

Qutrits in multiparticle systems

Quantum Electronics, 2007
The evolution of complex composite quantum systems which can be reduced to systems with a small dimensionality of the Hilbert space (of the qutrit, ququart type, etc.) is considered. In the case of the interaction of an ensemble of two-level atoms with light, the conditions are found under which a qutrit is produced from the light and atomic states ...
