High-Fidelity, Single-Shot, Quantum-Logic-Assisted Readout in a Mixed-Species Ion Chain
Colin Bruzewicz, Robert McConnell, Jonathon Sedlacek +4
We use a co-trapped ion () to sympathetically cool and measure the quantum state populations of a memory-qubit ion of a different atomic species ($^{40}\mathr…
High-Fidelity Ion State Detection Using Trap-Integrated Avalanche Photodiodes
David Reens, Michael Collins, Joseph Ciampi +12
Integrated technologies greatly enhance the prospects for practical quantum information processing and sensing devices based on trapped ions. High-speed and high-fidelity ion state…
Integrated multi-wavelength control of an ion qubit
Robert J. Niffenegger, Jules Stuart, Cheryl Sorace-Agaskar +10
Monolithic integration of control technologies for atomic systems is a promising route to the development of quantum computers and portable quantum sensors. Trapped atomic ions for…
Iterative Precision Measurement of Branching Ratios Applied to 5P states in 88Sr+
Helena Zhang, Michael Gutierrez, Guang Hao Low +4
We report on a method for measuring the branching ratios of dipole transitions of trapped atomic ions by performing nested sequences of population inversions. This scheme is broadl…
A Brillouin Laser Optical Atomic Clock
William Loh, Jules Stuart, David Reens +6
Over the last decade, optical atomic clocks have surpassed their microwave counterparts and now offer the ability to measure time with an increase in precision of two orders of mag…
