It is generally acknowledged that it is no longer socially acceptable to espouse prejudiced beliefs, yet prejudiced attitudes and discriminatory behaviours still occur. The present study sought to determine when and by whom prejudiced attitudes would be expressed. Specifically, an experiment was conducted to examine the impact of injunctive social norms emanating from a social group with which participants identified and participants' level of homophobia on the expression of opinions about gay men. Participants were presented with information indicating that the majority of group members agreed with a number of prejudiced injunctive statements (pro-prejudice norm), that the majority disagreed with the statements (anti-prejudice norm), or they were given no information about other group members' opinions (control). Participants then reported their own responses to the same injunctive statements. Participants' levels of homophobia were assessed either before or after they were given the normative information. The results indicated that activation of a pro-prejudice injunctive norm for those higher in homophobia resulted in more prejudiced opinions being expressed in comparison to those who received no normative information or those who had a nonprejudiced norm activated. Those lower in homophobia expressed less prejudiced opinions than those higher in homophobia and this did not differ as a function of social norm. The results demonstrate how prejudice can come to be expressed even in the presence of a broad societal norm that suggests that is it wrong to express such opinions.

We give a simple proof of a formula for the minimal time required to simulate a two-qubit unitary operation using a fixed two-qubit Hamiltonian together with fast local unitaries. We also note that a related lower bound holds for arbitrary n-qubit gates.

In this paper we investigate the effect of dephasing on proposed quantum gates for the solid-state Kane quantum computing architecture. Using a simple model of the decoherence, we find that the typical error in a controlled-NOT gate is 8.3x10(-5). We also compute the fidelities of Z, X, swap, and controlled Z operations under a variety of dephasing rates. We show that these numerical results are comparable with the error threshold required for fault tolerant quantum computation.
