Extension of the Morris-Shore transformation to multilevel ladders
نویسندگان
چکیده
We describe situations in which chains of N degenerate quantum energy levels, coupled by time-dependent external fields, can be replaced by independent sets of chains of length N, N−1, . . . ,2 and sets of uncoupled single states. The transformation is a generalization of the two-level Morris-Shore transformation J.R. Morris and B.W. Shore, Phys. Rev. A 27, 906 1983 . We illustrate the procedure with examples of three-level chains.

In this paper, we use stimulated Raman adiabatic passage technique to implement single-qutrit quantum gates in tripod systems. It is shown by using the Morris-Shore (MS) transformation, the six-state problem with 5 pulsed fields can be reduced to a basis that decouples two states from the others. This imposes three pulses not connected to the initial condition with have the same shape. Using th...
متن کاملNew Coupled-Inductor Based Multilevel Inverter with Extension Capability
Multilevel inverters have been developed due to limitations of the conventional two-level voltage source inverters (VSIs). Most of the topologies of multilevel inverters that have been presented in the literature are based on the sharing of the rated voltage between the switches so that the switches with lower voltage ratings can be used. In these topologies, the current rating of all of the sw...
متن کاملA Direct Power Feeding System for AC Railway Networks Using Modular Multilevel Converter
Abstract Traditional railway power supply systems impose substantial power quality problems (PQ) on the utility network, such as unbalance, harmonics and a large amount of reactive power. This paper proposes a topology based on three-phase to single-phase modular multilevel converters (MMC) to obviate these problems. The MMC based traction substations (TSS) are connected directly to the utili...
متن کاملSandbar Migration Due to Cross-Shore Sediment Transport; A Case Study of Noshahr Coasts, Iran
Cross-shore sediment transport is one of the effective factors in erosion and sedimentation, and affects dynamics of the beach profile in coastal areas. Furthermore, sandbar migration due to cross-shore sediment transport mostly effects beach nourishment, displacement of pollutions trapped in sediments, and organism and plants’ lives. In this manuscript, sandbar migration due to cro...
