CLASSICAL COMMUNICATION COSTS IN QUANTUM INFORMATION PROCESSING

MING-XING LUO, Xiu‐Bo Chen, Yixian Yang +1 more

Classical communication plays an important role in quantum information processing such as remote state preparation and quantum teleportation. First, in this paper, we present some simple faithful remote state preparation of an arbitrary n-qubit state by constructing entanglement resources and special measurement basis for the sender. Then to weigh the classical resource required, we present an information-theoretical model to evaluate the classical communication cost. By optimizing the classical communication in quantum protocols, we obtain the optimal classical communication cost. This model can also be applied to the quantum teleportation. Moreover, based on the present computation model, we reinvestigate some remote state preparation and teleportation protocols in which the classical communication cost was imperfectly computed. Finally, some problems will be presented.Classical communication plays an important role in quantum information processing such as remote state preparation and quantum teleportation.

SEARCH FOR QUANTUM AND CLASSICAL MODES OF INFORMATION PROCESSING IN MICROTUBULES: IMPLICATIONS FOR “THE LIVING STATE”

Stuart R. Hameroff, Jack A. Tuszyński

Dynamical activities within living eukaryotic cells are organized by microtubules, main structural components of the cytoskeleton and cylindrical polymers of the protein tubulin. Evidence and theoretical models suggest that states of tubulin may play the role of “bits ” in classical microtubule computational automata. The advent of quantum information devices, key roles played by quantum processes in protein dynamics, and coherent ordering in the cell cytoplasm further suggest that microtubules may function as quantum computational devices, and that mesoscopic and macroscopic quantum states are characteristic of living systems. In this paper new results from molecular dynamics simulation based on recently obtained atomic structure of tubulin are presented which provide support for classical and quantum modes of microtubule information processing. 1.
