Towards quantum simulations of biological information flow

R. Dorner, J. Goold, V. Vedral
2012 Interface Focus  
For instance, in classical information theory, information is encoded within a bit that exists in one of two computational states, '0' or '1', at all times.  ...  Accordingly, the field quantum information theory has exploited quantum coherence to develop information processing schemes of superior power to their classical counterparts [7] .  ...

Gianlorenzo D'Angelo, Gabriele Di Stefano, Alfredo Navarra
2011 Proceedings of the 5th International Confernece on Ubiquitous Information Management and Communication - ICUIMC '11  
By switching among interfaces or by combining the available interfaces, each device might establish several connections.  ...  A connection is established when the devices at its endpoints share at least one active interface.
