Responsibility modulates neural mechanisms of outcome processing : an ERP study
The role of personal responsibility in decision-making and its influence on the outcome evaluation process have been investigated relatively rarely in cognitive neuroscience. The present event-related brain potential (ERP) study manipulated the subjective sense of responsibility by modifying outcome controllability in a gambling task. Participants reported a higher sense of responsibility and produced a larger fERN when they were told that the game was 'controllable' compared with when they were told that the game was 'uncontrollable.' In addition, fERN amplitude was correlatedwith individual self-reports of personal responsibility over the outcomes. These results indicate that self-attribution of responsibility associated with different degrees of controllability affects the outcome evaluation process and fERN amplitude
Multiparty quantum secret splitting and quantum state sharing
A protocol for multiparty quantum secret splitting is proposed with an
ordered EPR pairs and Bell state measurements. It is secure and has the
high intrinsic efficiency and source capacity as almost all the instances are
useful and each EPR pair carries two bits of message securely. Moreover, we
modify it for multiparty quantum state sharing of an arbitrary -particle
entangled state based on quantum teleportation with only Bell state
measurements and local unitary operations which make this protocol more
convenient in a practical application than others.Comment: 7 pages, 1 figure. The revision of the manuscript appeared in PLA.
