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…
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…
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…
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…
Fast entangling gates in long ion chains
Zain Mehdi, Alexander K. Ratcliffe, Joseph J. Hope
We present a model for implementing fast entangling gates (s) with ultra-fast pulses in arbitrarily long ion chains, that requires low numbers of pulses and can be imple…
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…
