Measurement-based ground state cooling of a trapped ion oscillator
Chungsun Lee, Simon C. Webster, Jacopo Mosca Toba +3
Measurement-based cooling is a method by which a quantum system, initially in a thermal state, can be prepared in its ground state through some sort of measurement. This is done by…
Certifying Multilevel Coherence in the Motional State of a Trapped Ion
Ollie Corfield, Jake Lishman, Chungsun Lee +6
Quantum coherence is one of the clearest departures from classical physics, exhibited when a system is in a superposition of different basis states. Here the coherent superposition…
Resilient entanglement gates for trapped ions
A. E. Webb, S. C. Webster, S. Collingbourne +5
Constructing a large scale ion trap quantum processor will require entangling gate operations that are robust in the presence of noise and experimental imperfection. We experimenta…
Generation of high-fidelity quantum control methods for multi-level systems
J. Randall, A. M. Lawrence, S. C. Webster +3
In recent decades there has been a rapid development of methods to experimentally control individual quantum systems. A broad range of quantum control methods has been developed fo…
Trapped-ion quantum logic with global radiation fields
S. Weidt, J. Randall, S. C. Webster +7
Trapped ions are a promising tool for building a large-scale quantum computer. However, the number of required radiation fields for the realisation of quantum gates in any proposed…
Ground-state cooling of a trapped ion using long-wavelength radiation
S. Weidt, J. Randall, S. C. Webster +5
We demonstrate ground-state cooling of a trapped ion using radio-frequency (RF) radiation. This is a powerful tool for the implementation of quantum operations, where RF or microwa…
Generation of spin-motion entanglement in a trapped ion using long-wavelength radiation
K. Lake, S. Weidt, J. Randall +3
Applying a magnetic field gradient to a trapped ion allows long-wavelength microwave radiation to produce a mechanical force on the ion's motion when internal transitions are drive…
Efficient preparation and detection of microwave dressed-state qubits and qutrits with trapped ions
J. Randall, S. Weidt, E. D. Standing +6
We demonstrate a method for preparing and detecting all eigenstates of a three-level microwave dressed system with a single trapped ion. The method significantly reduces the experi…
Simple Manipulation of a Microwave Dressed-State Ion Qubit
S. C. Webster, S. Weidt, K. Lake +2
Many schemes for implementing quantum information processing require that the atomic states used have a non-zero magnetic moment, however such magnetically sensitive states of an a…
Two-dimensional ion trap lattice on a microchip
R. C. Sterling, H. Rattanasonti, S. Weidt +5
Microfabricated ion traps are a major advancement towards scalable quantum computing with trapped ions. The development of more versatile ion-trap designs, in which tailored arrays…
