TRIAXIAL MAGNETIC FIELD CORRECTION COIL, PHYSICS PACKAGE, PHYSICS PACKAGE FOR OPTICAL LATTICE CLOCK, PHYSICS PACKAGE FOR ATOMIC CLOCK, PHYSICS PACKAGE FOR ATOM INTERFEROMETER, PHYSICS PACKAGE FOR QUANTUM INFORMATION PROCESSING DEVICE, AND PHYSICS PACKAGE SYSTEM
There is a need to maintain or enhance the magnetic field correction accuracy of a physics package while making the physics package more compact and portable. A triaxial magnetic field correction coil (96) is provided inside a vacuum chamber (20) surrounding a clock transition space (52) having atoms disposed therein. The triaxial magnetic field correction coil (96) is formed into a shape such that it is possible to correct, for magnetic field components of three axial directions passing through the clock transition space (52), a constant term, a first order spatial derivative term, a second order spatial derivative term, a third or higher order spatial derivative term, or some given combination of these terms. The triaxial magnetic field correction coil (96) can be used in, for example, a physics package (12) for an optical lattice clock.
