Active stabilization of ion trap radiofrequency potentials

Active stabilization of ion trap radiofrequency potentials.

We actively stabilize the harmonic oscillation frequency of a laser-cooled atomic ion confined in a radiofrequency (rf) Paul trap by sampling and rectifying the high voltage rf applied to the trap electrodes. We are able to stabilize the 1 MHz atomic oscillation frequency to be better than 10 Hz or 10 ppm. This represents a suppression of ambient noise on the rf circuit by 34 dB. This technique...

A linear radiofrequency ion trap for accumulation, bunching, and emittance improvement of radioactive ion beams

An ion beam cooler and buncher has been developed for the manipulation of radioactive ion beams. The gas-filled linear radiofrequency ion trap system is installed at the Penning trap mass spectrometer ISOLTRAP at ISOLDE/CERN. Its purpose is to accumulate the 60-keV continuous ISOLDE ion beam with high efficiency and to convert it into low-energy low-emittance ion pulses. The efficiency was foun...

Ion-Trap Quantum Computation

Quantum computation requires a very special physical environment. Numerous operations must be performed on the quantum states of the qubits (or quantum bits) before those states decohere, or lose the interlocking phase relationships that give quantum computation its power. Thought to be an unavoidable outcome of the interaction between the quantum state and the environment, decoherence threaten...
