Title: Transport of Quantum States and Separation of Ions in a Dual RF Ion Trap
Published: September 01, 2002
Abstract: We have investigated ion dynamics associated with a dual linear ion trap where ions can be stored in and moved betweenn two distinct locations. Such a trap is a building block for a system to engineer arbitrary quantum states of ion ensembles. Specifically, this trap is the unit cell in a strategy for scalable quantum computing using a series of interconnected ion traps. We have transferred an ion betwee trap locations 1.2 mm apart in 50 υs with near unit efficiency ({greater than} 10 6 consecutive transfers) and negligible motional heating, while maintaining internal-state coherence. In addition, we have separated two ions held in a common trap into two distinct traps.
