Unraveling spin dynamics from charge fluctuations
The use of single electron spins in quantum dots as qubits requires detailed
knowledge about the processes involved in their initialization and operation as
well as their relaxation and decoherence. In optical schemes for such spin
qubits, spin-flip Raman as well as Auger processes play an important role, in
addition to environment-induced spin relaxation. In this paper, we demonstrate
how to quantitatively access all the spin-related processes in one go by
monitoring the charge fluctuations of the quantum dot. For this, we employ
resonance fluorescence and analyze the charge fluctuations in terms of
waiting-time distributions and full counting statistics characterized by
factorial cumulants.Comment: 14 pages, 8 figure
The Neighborhood’s Catalogue: Lower East Side Planning and Design File
This catalogue was designed to support the process of slow redevelopment over time, combined with conservation of diverse social and historical continuity and the exploration of new land and building uses. The catalogue shows how to involve neighborhoods in participation, supportive design, incremental planning and phased development. This project was made possible by a grant from the National Endowment for the Arts. Reprinted in 1987.https://dc.uwm.edu/caupr_mono/1047/thumbnail.jp

Making Every Photon Count: A Quantum Polyspectra Approach to the Dynamics of Blinking Quantum Emitters at Low Photon Rates Without Binning
The blinking statistics of quantum emitters and their corresponding Markov
models play an important role in high resolution microscopy of biological
samples as well as in nano-optoelectronics and many other fields of science and
engineering. Current methods for analyzing the blinking statistics like the
full counting statistics or the Viterbi algorithm break down for low photon
rates. We present an evaluation scheme that eliminates the need for both a
minimum photon flux and the usual binning of photon events which limits the
measurement bandwidth. Our approach is based on higher order spectra of the
measurement record which we model within the recently introduced method of
quantum polyspectra from the theory of continuous quantum measurements. By
virtue of this approach we can determine on- and off-switching rates of a
semiconductor quantum dot at light levels 1000 times lower than in a standard
experiment and 20 times lower than achieved with a scheme from full counting
statistics. Thus a very powerful high-bandwidth approach to the parameter
learning task of single photon hidden Markov models has been established with
applications in many fields of science
