Quantum computing with identical atoms and fewer loopholes for Bell

Optical clock-transitions such as the ones in Ytterbium and Strontium atoms are prime candidates for encoding qubits for quantum information processing. In this work, we investigate the challenges involved in using these candidates for quantum information applications. We devise entangling operations for identical atoms trapped in optical tweezers, as well as determine the feasibility of rapid qubit rotation and measurement of qubits encoded in these desirable low-decoherence clock transitions. The rapid control of atomic qubits is crucial for high-speed synchronization of quantum information processors, but is also of interest for tests of Bell inequalities that avoid the detection loophole in spacelike separated entangled qubits.
