Query: Quantum harmonic oscillator state synthesis by reservoir engineering   The robust generation of quantum states in the presence of decoherence is a
primary challenge for explorations of quantum mechanics at larger scales. Using
the mechanical motion of a single trapped ion, we utilize reservoir engineering
to generate squeezed, coherent and displaced-squeezed states as steady states
in the presence of noise. We verify the created state by generating two-state
correlated spin-motion Rabi oscillations resulting in high contrast
measurements. For both cooling and measurement, we use spin-oscillator
couplings that provide transitions between oscillator states in an engineered
Fock state basis. Our approach should facilitate studies of entanglement,
quantum computation, and open-system quantum simulations in a wide range of
physical systems.
