    Quantum state protection using all-optical feedback

    No full text
    An all-optical feedback scheme in which the output of a cavity mode is used to influence the dynamics of another cavity mode is considered. We show that under ideal conditions, perfect preservation against decoherence of a generic quantum state of the source mode can be achieved.Comment: 10 pages, 4 figures, to appear in the Dan Walls Memorial Volume, edited by H.

    Marginal revenue product and salaries: Moneyball redux

    No full text
    Scully (1974) used a two equation regression model to estimate a baseball player’s salary to compare to the actual salary the player earned in order to determine if a player is paid his net marginal revenue product. We replicate the spirit of that paper, but introduce several useful innovations to estimate net marginal revenue products for a large sample of free-agent baseball players. Our results suggest that the highest paid free agents are overpaid, while all other free agents are underpaid or paid appropriately. We found no evidence for the notion that some clubs may be more adept at finding “bargain” free agents.net marginal revenue product; free agents; baseball

    Improving quantum microscopy and lithography via Raman photon pairs: II. analysis

    No full text
    We show that by using the strongly correlated photon pairs generated in a Raman quantum erasure scheme (Scully M and Druhl K 1982 Phys. Rev. A 25 2208), it is possible to exceed the Rayleigh resolution limit of classical microscopy. The complete analysis of the underlying physics is given here. Further discussion of the physics and potential applications are presented in a companion paper (Scully M O 2004 Improving quantum microscopy and lithography via Raman photon pairs: I. Biological applications, submitted)

    Columbus Community Legal Services:Location, Location, Location!

    This year’s annual Mirror of Justice Lecture, sponsored by the Pope John Paul II Guild of Catholic Lawyers, traced the evolution of the law school’s legal clinic and highlighted its place in the local community as an oasis of justice, compassion and help. Professor Ellen Scully, who was the director of Columbus Community Legal Services for 25 years, noted in her Oct. 28 remarks that the clinic was patterned from the beginning after a law firm, a model that has worked exceptionally well over the years. “Columbus Community Legal Services is a special place, reflective of the mission of the Church and the law school. Everybody is a stakeholder in it. It attracts special people,” said Scully. A summary of the event is available here
