Shuttling of Rydberg Ions for Fast Entangling Operations.

Summary of "Shuttling of Rydberg Ions for Fast Entangling Operations."

We introduce a scheme to entangle Rydberg ions in a linear ion crystal, using the high electric polarizability of the Rydberg electronic states in combination with mutual Coulomb coupling of ions that establishes common modes of motion. After laser initialization of ions to a superposition of ground and Rydberg states, the entanglement operation is driven purely by applying a voltage pulse that shuttles the ion crystal back and forth. This operation can achieve entanglement on a sub-μs timescale, more than 2 orders of magnitude faster than typical gate operations driven by continuous-wave lasers. Our analysis shows that the fidelity achieved with this protocol can exceed 99.9% with experimentally achievable parameters.

Cell membrane glycoproteins selective for sodium ions. Fast sodium current is associated with the action potential in neural membranes.

The movement of ions across energy-transducing cell membranes. Transport can be active, passive or facilitated. Ions may travel by themselves (uniport), or as a group of two or more ions in the same (symport) or opposite (antiport) directions.

A group of techniques developed to apply scientific methods and tools to solve the problems of DECISION MAKING in complex organizations and systems. Operations research searches for optimal solutions in situations of conflicting GOALS and makes use of mathematical models from which solutions for actual problems may be derived.
