Contract signing with decoherence
We present a fair contract signing protocol without communication
with a judge during the exchange phase. To this end we use
particular Werner states and assume that the agents have no control
over the system decoherence. Finally, we show how to implement such
Werner states and discuss some limitations and extensions of the
proposed protocol (joint work with J. Bouda and N. Paunkovic).
This seminar will be held in the Alameda campus!
