Error-Resilient Fast Entangling Gates for Scalable Ion-Trap Quantum Processors
Isabelle Savill-Brown, Zain Mehdi, Alexander K. Ratcliffe +5
Non-adiabatic two-qubit gate proposals for trapped-ion systems offer superior performance and flexibility over adiabatic schemes at the cost of increased laser control requirements…
High-speed and high-connectivity two-qubit gates in long chains of trapped ions
Isabelle Savill-Brown, Joseph J. Hope, Alexander K. Ratcliffe +5
We present a theoretical study of fast all-to-all entangling gates in trapped-ion quantum processors, based on impulsive excitation of spin-dependent motion with broadband laser pu…
Radial Fast Entangling Gates Under Micromotion in Trapped-Ion Quantum Computers
Phoebe Grosser, Monica Gutierrez Galan, Isabelle Savill-Brown +7
Micromotion in radio-frequency ion traps is generally considered detrimental for quantum logic gates, and is typically minimized in state-of-the-art experiments. However, as a dete…
Multimode feedback cooling of the collective modes of a Bose-Einstein condensate
Ryan J. Thomas, Jordan A. McMahon, Zain Mehdi +5
We experimentally demonstrate cavity-free feedback cooling of the three lowest-lying collective modes of a Bose-Einstein condensate in a prolate harmonic trap. Using shadowgraph im…
Multi-mode cooling of a Bose-Einstein condensate with linear quantum feedback
Zain Mehdi, Matthew L. Goh, Matthew J. Blacker +2
We theoretically investigate measurement-based feedback control over the motional degrees of freedom of an oblate quasi-2D atomic Bose-Einstein condensate (BEC) subject to continuo…
Fast mixed-species quantum logic gates for trapped-ion quantum networks
Zain Mehdi, Varun D. Vaidya, Isabelle Savill-Brown +6
Quantum logic operations between physically distinct qubits is an essential aspect of large-scale quantum information processing. We propose an approach to high-speed mixed-species…
