“…The use of charged particles in Penning traps for quantum information processing is being investigated by a number of groups [9,10,11,12,13,14,15,16]. By contrast with RF traps, there is no inherent heating of the ions by the trapping fields since only static fields are employed.…”

We report the experimental characterization of axialization -a method of reducing the magnetron motion of a small number of ions stored in a Penning trap. This is an important step in the investigation of the suitability of Penning traps for quantum information processing. The magnetron motion was coupled to the laser-cooled modified cyclotron motion by the application of a nearresonant oscillating quadrupole potential (the "axialization drive"). Measurement of cooling rates of the radial motions of the ions showed an order-of-magnitude increase in the damping rate of the magnetron motion with the axialization drive applied. The experimental results are in good qualitative agreement with a recent theoretical study. In particular, a classical avoided crossing was observed in the motional frequencies as the axialization drive frequency was swept through the optimum value, proving that axialization is indeed a resonant effect.

“…These observations made possible the most precise measurements of the electron magnetic moment and the fine structure constant [2]. The one-electron observations also triggered intriguing studies on using oneelectron qubits as building blocks for quantum information processing [3][4][5][6][7][8][9][10][11][12][13][14]. The possibility of a very long coherence time is very attractive.…”

A one-electron qubit would offer a new option for quantum information science, including the possibility of extremely long coherence times. One-quantum cyclotron transitions and spin flips have been observed for a single electron in a cylindrical Penning trap. However, an electron suspended in a planar Penning trap is a more promising building block for the array of coupled qubits needed for quantum information studies. The optimized design configurations identified here promise to make it possible to realize the elusive goal of one trapped electron in a planar Penning trap for the first time -a substantial step toward a one-electron qubit.

“…This system allows the m easurem ent o f fundamental physical con stants with striking accuracy and is reasonably free of decoherence and dissipation [9]. As a consequence, the determ ination (or the reconstruction [10]) o f the entangled quantum state o f the trapped electron is a decisive issue, especially in the light o f the fact that such a system has been already proposed as a candi date for quantum inform ation processing [11].…”
