Entropic Heisenberg limits and uncertainty relations from the Holevo information bound [PDF]

, 2018
Strong and general entropic and geometric Heisenberg limits are obtained, for estimates of multiparameter unitary displacements in quantum metrology, such as the estimation of a magnetic field from the induced rotation of a probe state in three ...

An Optical Coordinate Measuring Machine for Nanoscale Dimensional Metrology

Journal of Advanced Computational Intelligence and Intelligent Informatics, 2004
Coordinate Measuring Machines (CMMs) are commonly used for geometry verification and replication on solid parts and work pieces on many scales. As the parts predicable continues to grow smaller and smaller, so grows the need to accurately measure the dimensional accuracy of these parts.

High Entropy Wide‐Bandgap Borates with Broadband Luminescence and Large Nonlinear Optical properties

Advanced Functional Materials, EarlyView.
High‐entropy rare‐earth borates exhibit excellent nonlinear optical and broadband luminescence properties arising from multi‐component doping, chemical disorder, increased configurational entropy, and increased lattice and electronic anharmonicity. This formulation enabled us to obtain a large, environmentally stable single crystal with 3X higher laser‐
