High-Fidelity Raman Spin-Dependent Kicks in the Presence of Micromotion

Haonan Liu, Varun D. Vaidya, Monica Gutierrez Galan +3

We propose high-fidelity single-qubit spin-dependent kicks (SDKs) for trapped ions using nanosecond Raman pulses via amplitude modulation of a continuous-wave laser with a tunable…

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…

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…

Scalable quantum computation with fast gates in two-dimensional microtrap arrays of trapped ions

Zain Mehdi, Alexander K. Ratcliffe, Joseph J. Hope

We theoretically investigate the use of fast pulsed two-qubit gates for trapped ion quantum computing in a two-dimensional microtrap architecture. In one dimension, such fast gates…

Optimised fast gates for quantum computing with trapped ions

Evan P. G. Gale, Zain Mehdi, Lachlan M. Oberg +3

We present an efficient approach to optimising pulse sequences for implementing fast entangling two-qubit gates on trapped ion quantum information processors. We employ a two-phase…

Micromotion-Enhanced Fast Entangling Gates For Trapped Ion Quantum Computing

Alexander K. Ratcliffe, Lachlan M. Oberg, Joseph J. Hope

RF-induced micromotion in trapped ion systems is typically minimised or circumvented to avoid off-resonant couplings for adiabatic processes such as multi-ion gate operations. Non-…

Scaling Trapped Ion Quantum Computers Using Fast Gates and Microtraps

Alexander K. Ratcliffe, Richard L. Taylor, André R. R. Carvalho +1

Most attempts to produce a scalable quantum information processing platform based on ion traps have focused on the shuttling of ions in segmented traps. We show that an architectur…
