Precision and Accuracy of Thermal Calibration of Atomic Force Microscopy Cantilevers

January 1, 2006
Author(s)
G A. Matei, E J. Thoreson, Jon R. Pratt, David B. Newell, N A. Burnham
To have confidence in force measurements made with atomic force microscopes (AFMs), the spring constant of the AFM cantilevers should be known with good precision and accuracy, topics not yet thoroughly treated in the literature. In this study, we compared

Progress Towards a Precision Measurement of the Neutron Lifetime Using Magnetically Trapped Ultracold Neutrons

P.-N. Seo, Kevin Coakley, J M. Doyle, F H. DuBose, R Golub, E Korobkina, S K. Lamoreaux, Hans Pieter Mumm, C M. O'Shaughnessy, G R. Palmquis, A K. Thompson, Grace L. Yang, L Yang, Paul R. Huffman
As part of an on-going program utilizing magnetically trapped ultracold neutrons (UCNs,) we are developing a technique that offers the possibility of improving the precision of the neutron lifetime by more than an order of magnitude. The experiment works

Protected Realizations of Quantum Information

January 1, 2006
Author(s)
Emanuel H. Knill
There are two complementary approaches to realizing quantum information so that it is protected from a given set of error operators. Both involve encoding information by means of subsystems. Initialization-based error protection involves a quantum
