Physical property measurements of doped cesium iodide crystals

Mechanical and thermal property values are reported for crystalline cesium iodide doped with sodium and thallium. Young's modulus, bulk modulus, shear modulus, and Poisson's ratio were obtained from ultrasonic measurements. Young's modulus and the samples' elastic and plastic behavior were also measured under tension and compression. Thermal expansion and thermal conductivity were the temperature dependent measurements that were made

Perfect quantum transport in arbitrary spin networks

Spin chains have been proposed as wires to transport information between distributed registers in a quantum information processor. Unfortunately, the challenges in manufacturing linear chains with engineered couplings has hindered experimental implementations. Here we present strategies to achieve perfect quantum information transport in arbitrary spin networks. Our proposal is based on the weak coupling limit for pure state transport, where information is transferred between two end-spins that are only weakly coupled to the rest of the network. This regime allows disregarding the complex, internal dynamics of the bulk network and relying on virtual transitions or on the coupling to a single bulk eigenmode. We further introduce control methods capable of tuning the transport process and achieve perfect fidelity with limited resources, involving only manipulation of the end-qubits. These strategies could be thus applied not only to engineered systems with relaxed fabrication precision, but also to naturally occurring networks; specifically, we discuss the practical implementation of quantum state transfer between two separated nitrogen vacancy (NV) centers through a network of nitrogen substitutional impurities.Comment: 5+7 page

ERP Initiation - A Historical Perspective

In a competitive environment, firms continually need to find better business solutions with flexible and marketing-oriented structures. They need to establish new business objectives to fulfill their corporate visions. A whole organization should be aligned to achieve these objectives. Information technology (IT) needs to be aligned to the organization\u27s mission. IT professionals have provided systems to the organization and in most cases, these systems consist of individual functions, which should be used in an integrated manner. Enterprise Resource Planning (ERP) software has emerged to offer an integrated solution. It is suggested that ERP could facilitate the compatibility between task characteristics and technology characteristics, a long overdue IT solution. Some useful information about ERP can be found by examining the evolution of ERP from MRP
