Zero-field identification and control of hydrogen-related electron-nuclear spin registers in diamond
Alexander Ungar, Hao Tang, Andrew Stasiuk +5
Spin defects in diamond serve as powerful building blocks for quantum technologies, especially for applications in quantum sensing and quantum networking. Electron-nuclear defects…
Exponential onset of scalable entanglement via twist-and-turn dynamics in XY models
Tommaso Roscilde, Meenu Kumari, Alexandre Cooper +1
The efficient preparation of scalable multipartite entanglement is a central goal in the development of next-generation quantum devices. In this work, we show that the so-called ``…
Quantum channel for modeling spin-motion dephasing in Rydberg chains
Christopher Wyenberg, Kent Ueno, Alexandre Cooper
We introduce a quantum channel to model the dissipative dynamics resulting from the coupling between spin and motional degrees of freedom in chains of neutral atoms with Rydberg in…
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. III. The bird and batching algorithms and other parallel implementations on GPUs
Fouad Afiouni, Remy El Sabeh, Naomi Nishimura +3
We present efficient implementations of atom reconfiguration algorithms for both CPUs and GPUs, along with a batching routine to merge displacement operations for parallel executio…
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…
