Quantum Information Technology

Spiller, Timothy

HPL-2002-319

Keyword(s): quantum information; quantum computing; quantum cryptography; quantum teleportation

Abstract: A new quantum information technology (QIT) could emerge in the future, based on current research in the fields of quantum information processing and communication (QIPC). In contrast to conventional IT, where quantum mechanics plays a support role in improving the building blocks, fundamental quantum phenomena play a central role for QIPC - information is stored, processed and communicated according to the laws of quantum physics. This additional freedom could enable future QIT to perform tasks we will never achieve with ordinary IT. This article provides an introduction to QIPC, some indication of the state of play today, and some comments on the future.
