    Control of Entanglement in Ising-type Networks With One and Two Excitations

  • Original language description

    We analyze the dynamics of single and two particle states in Ising-type networks. The mutual entanglement is quantified using the concept of concurrence. We derive explicit expressions for the concurrence for single and two particle initial states in arbitrary passive networks and specify the result for Ising-type networks. We show how to design a network to prepare a prescribed pattern of entanglement for one excitation and study the maximum attainable entanglement for passive optical networks in general. The effect of network randomization on average entanglement is also studied.

    Kontrola entanglementu v Ising-podobne siti s jednou a dvema excitacemi

  • Czech description

    Studujeme dynamiku jedné a dvou excitací v sítích Isingovského typu. Pomocí konkurence charakterizujeme vzájemné provázání mezi mody. Odvozujeme explicitní výrazy pro konkurenci pro jedno a dvou částicové vstupní stavy v pasivních sítích a specifikujemevýsledek pro Isingovskou sít. Odvozujeme jak navrhnout sít, která realizuje předepsanou strukturu provázání a studujeme maximální provázání, které je možno získat pro pasivní optické sítě. Studujeme taky vliv randomizace sítě na provázání.
