Quantum control and spectroscopy of a polyatomic molecular ion
Abstract
Quantum control of trapped atoms has revolutionized precision metrology and research, enabling breakthroughs such as the worldÕs best atomic clocks, quantum information processing, and tests of fundamental physics. Achieving a similar level of control for molecules is a longstanding goal, with exciting applications such as deeper understanding of the physics of molecules, providing new platforms for quantum information processing, and testing fundamental physics. Recently, trapping, cooling, and probabilistic preparation in a single quantum state of the diatomic molecular ion CaH+ was realized in a proof-of-principle experiment using quantum-logic spectroscopy. The experiment demonstrated that it is possible to manipulate quantum states of molecules with similar control that scientists have over atoms. The goal of this proposal is to expand the molecular ion quantum control toolbox to include generation and characterization of quantum superposition and entangled states (year 1) and toward deterministic pure state preparation of CaH+ (year 2), and to apply these tools to perform state preparation and spectroscopy of the hyperfine structure of a polyatomic molecular ion, N2H+, in a cryogenic environment (year 3).
