Controlled insertion of one and two atoms into a high-finesse optical cavity

摘要: Entangled quantum states have applications as a model system for strongly correlated many body states, resource information processing and tool enhanced precision measurements. Deterministic entanglement schemes create the desired state by transferring under action of carefully chosen Hamiltonian into an entangled state. The must follow unitary evolution, uncontrolled parasitic interactions with environment leading to spontaneous decay or partial measurements be avoided. paper present experiment, on loading number Doppler-cooled caesium atoms from magneto-optical trap standing wave optical dipole trap. positions individual are then determined sub-micrometer precision, enabling prepare, manipulate read out each atom. Using conveyor belt, transported mode high-finesse cavity.
