Trapped-ion qubits store information in the electronic states of atomic ions that are maintained in position in free space by a confining field. Performing arbitrary operations using several qubits requires the ability to entangle them, a goal that for trapped-ion qubits is typically obtained by coupling their motional quantum states. This coupling has been realized with excellent fidelity — a measure of how close a qubit is to its expected state during operation — using laser light. Now, Daniel Slichter and collaborators report a laser-free method to entangle two trapped-ion qubits. The new method, which is based on an oscillating radiofrequency magnetic field gradient combined with microwave magnetic fields, results in comparable fidelity to laser-based methods, but works about four times faster. The same radiofrequency control fields are used to address individual qubits and entangle them with one another. The scheme is robust against various types of decoherence and is compatible with any trapped ion species. Because this method can be extended to perform simultaneous entangling operations on different pairs of ions without increases in complexity, it has potential for the realization of large-scale trapped-ion quantum processors.
