Unpublished opening lecture for the course on the theory of relativity in Argentina, 1925

Albert Einstein, Alejandro Gangui, and Eduardo L Ortiz

Audio, Transactions of the IRE Professional Group on (2009)

Honorable Rector, Honorable Professors, and Students of this University: In these times of political and economic struggle and nationalistic fragmentation, it is a particular joy for me to see people assembling here to give their attention exclusively to the highest values that are common to us all. I am glad to be in this blessed land before a small circle of people who are interested in topics of science to speak on those issues that, in essence, are the subject of my own meditations.. [abridged].

  1. Fundamental quantum limit to waveform estimation.
    Mankei M Tsang, Howard M HM Wiseman, and Carlton M CM Caves

    We derive a quantum Cramér-Rao bound (QCRB) on the error of estimating a time-changing signal. The QCRB provides a fundamental limit to the performance of general quantum sensors, such as gravitational-wave detectors, force sensors, and atomic magnetometers. We apply the QCRB to the problem of forc...

    We analyze a proposed experiment [S. Boixo et al., Phys. Rev. Lett. 101, 040403 (2008)] for achieving sensitivity scaling better than $1/N$ in a Nonlinear Ramsey interferometer that uses a two-mode Bose-Einstein condensate (BEC) of $N$ atoms. We present numerical simulations that confirm the Analyti...

  3. Generalized limits for single-parameter quantum estimation.
    Sergio S Boixo, Steven T ST Flammia, ... J M JM Geremia

    Phys Rev Lett 98(9):090401 (2007) PMID 17359140

    We develop generalized bounds for quantum single-parameter estimation problems for which the coupling to the parameter is described by intrinsic multisystem interactions. For a Hamiltonian with k-system parameter-sensitive terms, the quantum limit scales as 1/Nk, where N is the number of systems. Th...
