LMI Seminar: Precision Spectroscopy in engineered subspaces
Roee Ozeri, Weizmann Institute
Noise limits the coherence of quantum superpositions thus compromising the precision with which spectroscopy can be performed. In the field of quantum information processing several methods were developed that mitigate the effect of noise on quantum coherence. Examples include, dynamic decoupling (DD), decoherence-free-subspaces (DFS) and quantum error-correction codes. In this talk I will describe the use of Hilbert space engineering to improve on the precision of spectroscopy in trapped-ion experiments, and their implication on the detection of new fundamental physics.
