Low-latency control system for feedback experiments with optical tweezer arrays
Amir H. Dadpour, Timur Khayrullin, Fouad Afiouni +4
We present and characterize a modular, open-source system to perform feedback control experiments on configurations of atoms and molecules in arrays of optical tweezers. The system…
Efficient algorithms to solve atom reconfiguration problems. II. The assignment-rerouting-ordering (aro) algorithm
Remy El Sabeh, Jessica Bohm, Zhiqian Ding +5
Programmable arrays of optical traps enable the assembly of configurations of single atoms to perform controlled experiments on quantum many-body systems. Finding the sequence of c…
Alkaline earth atoms in optical tweezers
Alexandre Cooper, Jacob P. Covey, Ivaylo S. Madjarov +3
We demonstrate single-shot imaging and narrow-line cooling of individual alkaline earth atoms in optical tweezers; specifically, strontium-88 atoms trapped in lig…
Improved entanglement detection with subspace witnesses
Won Kyu Calvin Sun, Alexandre Cooper, Paola Cappellaro
Entanglement, while being critical in many quantum applications, is difficult to characterize experimentally. While entanglement witnesses based on the fidelity to the target entan…
Identification and control of electron-nuclear spin defects in diamond
Alexandre Cooper, Won Kyu Calvin Sun, Jean-Christophe Jaskula +1
We experimentally demonstrate an approach to scale up quantum devices by harnessing spin defects in the environment of a quantum probe. We follow this approach to identify, locate,…
Compressing measurements in quantum dynamic parameter estimation
Easwar Magesan, Alexandre Cooper, Paola Cappellaro
We present methods that can provide an exponential savings in the resources required to perform dynamic parameter estimation using quantum systems. The key idea is to merge classic…
