An Integrated Ultralow Noise Spiral Interferometric Laser
William Loh, David Reens, Dave Kharas +14
Photonic integration offers the potential to bring complex high-performance optical systems to the form factor of a compact semiconductor chip. However, the range of system functio…
Real-time magnetic field noise correction using trapped-ion monitor qubits
Kyle DeBry, Agustin Valdes-Martinez, David Reens +2
We demonstrate a trapped-ion protocol in which a nearby, dedicated "monitor" qubit tracks magnetic-field drifts in real time without interrupting data-qubit operations. Using two $…
Error correction of a logical qubit encoded in a single atomic ion
Kyle DeBry, Nadine Meister, Agustin Valdes Martinez +6
Quantum error correction (QEC) is essential for quantum computers to perform useful algorithms, but large-scale fault-tolerant computation remains out of reach due to demanding req…
Optical Atomic Clock Interrogation Via an Integrated Spiral Cavity Laser
William Loh, David Reens, Dave Kharas +18
Optical atomic clocks have demonstrated revolutionary advances in precision timekeeping, but their applicability to the real world is critically dependent on whether such clocks ca…
Experimental quantum channel discrimination using metastable states of a trapped ion
Kyle DeBry, Jasmine Sinanan-Singh, Colin D. Bruzewicz +6
We present experimental demonstrations of accurate and unambiguous single-shot discrimination between three quantum channels using a single trapped ion. The th…
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…
