Bilayer crystals of trapped ions for quantum information processing

March 25, 2024
Samarth Hawalder, Prakriti Shahi, Allison Carter, Ana Maria Rey, John J. Bollinger, Athreya Shankar
Trapped ion systems are a leading platform for quantum information processing, but they are currently limited to 1D and 2D arrays, which imposes restrictions on both their scalability and their range of applications. Here, we propose a path to overcome

Individual qubit addressing of rotating ion crystals in a Penning trap

July 25, 2022
Anthony M. Polloreno, Ana Maria Rey, John J. Bollinger
Trapped ions boast long coherence times, and excellent gate fidelities, making them a useful platform for quantum information processing. Scaling to larger numbers of ion qubits, potentially solved by photonic interconnects between Paul traps, or by

Collective P-Wave Orbital Dynamics of Ultracold Fermions

September 28, 2021
Mikhail Mamaev, Peiru He, Thomas Bilitewski, Vijin Venu, Joseph Thywissen, Ana Maria Rey
We introduce a protocol to observe p-wave interactions in ultracold fermionic atoms loaded in a 3D optical lattice. Our scheme uses specific motionally excited band states to form an orbital subspace immune to band relaxation. A laser dressing is applied

Quantum-enhanced sensing of displacements and electric fields with large trapped-ion crystals

August 6, 2021
Kevin Gilmore, Matthew Affolter, Judith Jordan, Diego Barberena, Robert Lewis-Swan, Ana Maria Rey, John J. Bollinger
Developing the isolation and control of ultracold atomic systems to the level of single quanta has led to significant advances in quantum sensing, yet demonstrating a quantum advantage in real world applications by harnessing entanglement remains a core

Dipole-Dipole Frequency Shifts in Multilevel Atoms

June 30, 2021
Andre Cidrim, Asier Pineiro Orioli, Christian Sanner, Ross B. Hutson, Jun Ye, Romain Bachelard, Ana Maria Rey
Dipole-dipole interactions lead to frequency shifts which are expected to limit the performance of next generation atomic clocks. In this work, we compute dipolar frequency shifts accounting for the intrinsic atomic multilevel structure in standard Ramsey
