Abstract

We excited a transition between ground-state Zeeman sublevels in 40Ca+ using a radio frequency (RF) magnetic field. We discuss methods for generating an RF magnetic field of sufficiently large amplitude and for estimating the amplitude of the RF field to observe Rabi oscillations with high Rabi frequencies. A maximum Rabi frequency of ∼250 kHz was obtained. We also demonstrate a simple quantum gate operation on a combined system using the S1/2–D5/2 transition in 40Ca+.

Progress Towards the Quantum Control of the Zeeman Sublevels of Ultracold 87Rb Atoms

S. Martínez Sánchez, C. J. Ruiz Loredo, G. Ortiz Ugalde +3 more

This work presents the design and implementation of an RF system for the manipulation of the Zeeman sublevels of the87Rb atomic ground-state. This system allows efficient generation, control and transmission of the RF field that interacts with the atoms, facilitating the preparation of quantum states on demand via Rabi oscillations, while fine-tuning experimental parameters such as signal intensity and frequency. As Zeeman levels are highly sensitive to external magnetic fields, the system facilitates radio frequency spectroscopy, enabling precise measurement of such fields.

Observation of Mössbauer resonance line splitting caused by Rabi oscillations

Ilkka Juhani Tittonen, Mikk Lippmaa, Erkki Ikonen +2 more

We present the first experimental observation of the Rabi splitting of M\"ossbauer resonance lines. A radio-frequency magnetic field is tuned to induce transitions between hyperfine sublevels of the Zeeman-split excited or ground state of $^{57}\mathrm{Fe}$ nuclei. The line splitting corresponding to the Rabi flopping frequency is observed using a magnetically soft $^{57}\mathrm{FeNi}$ absorber foil of composition with almost zero magnetostriction.

Experimental study of one- and two-photon Rabi oscillations

T. Gentile, Barbara J. Hughey, Daniel Kleppner +1 more

We report an experimental study of one- and two-photon Rabi oscillations and other coherent effects in microwave transitions between Rydberg states of calcium. Selective field ionization allows us to observe the time evolution of both the initial and final states with high discrimination. The experiments include measurements of the dependence of the one- and two-photon oscillation frequencies on microwave power and detuning from resonance. We have used the off-resonant behavior of the two-photon oscillation frequency to measure the ac Stark shift. In a magnetic field we have also observed the free evolution of the magnetic sublevels and the effect of Zeeman splitting on the one-photon Rabi oscillations. The theory for these experiments is presented; our results are in excellent agreement.

Effect of the Bloch-Siegert shift on the frequency responses of Rabi oscillations in the case of nutation resonance

A. P. Saǐko, Г. Г. Федорук

The dynamics of a two-level spin system dressed by bichromatic radiation is studied under the conditions of double resonance when the frequency of one (microwave) field is equal to the Larmor frequency of the spin system and the frequency of the other (radio-frequency) field ω rf is close to the Rabi frequency ω 1 in a microwave field. It is shown theoretically that Rabi oscillations between dressed-spin states with the frequency ɛ are accompanied by higher-frequency oscillations at frequencies n ω rf and n ω rf ± ɛ, where n = 1, 2,.... The most intense among these are the signals corresponding to n = 1. The counter-rotating (antiresonance) components of the RF field give rise to a shift of the dressed-state energy, i.e., to a frequency shift similar to the Bloch-Siegert shift. In particular, this shift is manifested as the dependence of the Rabi-oscillation frequency ɛ on the sign of the detuning ω 1 − ω rf from resonance. In the case of double resonance, the oscillation amplitude is asymmetric; i.e., the amplitude at the sum frequency ω rf + ɛ increases, while the amplitude at the difference frequency ω rf − ɛ decreases. The predicted effects are confirmed by observations of the nutation signals of the electron paramagnetic resonance (EPR) of E ′ 1 centers in quartz and should be taken into account to realize qubits with a low Rabi frequency in solids.

On Rabi oscillations in ground hyperfine states of 87Rb atom driven by a microwave field

S. Sarkar, Vivek Singh, K. A. P. Singh +3 more

Abstract We have observed the Rabi oscillations of the population of 87 Rb atoms in the hyperfine ground state, when a cold atom cloud prepared in the hyperfine ground state (F = 1) was exposed to a microwave (MW) radiation field resonant to the |F = 1, m F = 0 > → |F = 2, m F = 0 > transition. After exposure to MW field, the atom cloud was imaged using the absorption probe method, and the cloud images have revealed that the population excited to the hyperfine state (F = 2) varied with the position in the atom cloud. At a given position in the atom cloud, the excited population shows Rabi oscillations between two hyperfine states with an increase in the MW field exposure time. Using these Rabi oscillations, the amplitude of the microwave magnetic field was estimated, which showed good agreement with the calculated field values. PACS numbers: 32.80.Pj, 33.55.Be, 67.85.-d.
