Condensed matter physics is a study of complex phenomena arising from interactions of many particles it includes studies of solids liquids gases plasmas bio molecules etc where even fundamentally very simple constituent particles electrons grain of sand etc can lead to complex behaviors in systems consisting of 10 23 particles. Condensed matter is one of the most active fields of physics with a stream of discoveries in areas from superfluidity and magnetism to the optical electronic and mechanical properties of materials this book presents state of the art research in this field. There are many aspects of quantum information that condensed matter physics can address coherence entanglement fabrication of nanoscale elements and the communication between them to name but a few many proposed schemes have in common the fabrication of nanostructures and communication links that incorporate a method of quantum control we are exploring the application of spintronics and novel materials such as cnts or graphene to quantum information spintronics experiments require a . Condensed matter physicists study matter in its nearly unlimited variety of condensed states from liquids to crystalline solids from thin films to fabricated or chemically synthesized nanostructures from quantum hall electron gases to superconductors from carbon nanotubes to liquid crystals and from amorphous structures to complex fluids we seek both to clarify the fundamental issues behind the striking properties of these systems and to illuminate their potential for useful
