Implementing Fault-tolerant Entangling Gates on the Five-qubit Code and the Color Code
C. Ryan-Anderson, N. C. Brown, M. S. Allman +34
We compare two different implementations of fault-tolerant entangling gates on logical qubits. In one instance, a twelve-qubit trapped-ion quantum computer is used to implement a n…
A high fidelity light-shift gate for clock-state qubits
C. H. Baldwin, B. J. Bjork, M. Foss-Feig +7
To date, the highest fidelity quantum logic gates between two qubits have been achieved with variations on the geometric-phase gate in trapped ions, with the two leading variants b…
Chip-integrated voltage sources for control of trapped ions
J. Stuart, R. Panock, C. D. Bruzewicz +5
Trapped-ion quantum information processors offer many advantages for achieving high-fidelity operations on a large number of qubits, but current experiments require bulky external…
Evidence for multiple mechanisms underlying surface electric-field noise in ion traps
J. A. Sedlacek, J. Stuart, D. H. Slichter +4
Electric-field noise from ion-trap electrode surfaces can limit the fidelity of multiqubit entangling operations in trapped-ion quantum information processors and can give rise to…
Method for Determination of Technical Noise Contributions to Ion Motional Heating
J. A. Sedlacek, J. Stuart, W. Loh +4
Microfabricated Paul ion traps show tremendous promise for large-scale quantum information processing. However, motional heating of ions can have a detrimental effect on the fideli…
Distance scaling of electric-field noise in a surface-electrode ion trap
J. A. Sedlacek, A. Greene, J. Stuart +4
We investigate anomalous ion-motional heating, a limitation to multi-qubit quantum-logic gate fidelity in trapped-ion systems, as a function of ion-electrode separation. Using a mu…
Intracavity Rydberg atom electromagnetically induced transparency using a high finesse optical cavity
Jiteng Sheng, Yuanxi Chao, Santosh Kumar +3
We present an experimental study of cavity assisted Rydberg atom electromagnetically induced transparency (EIT) using a high-finesse optical cavity (). Rydberg atoms…
High-Fidelity, Single-Shot, Quantum-Logic-Assisted Readout in a Mixed-Species Ion Chain
Colin Bruzewicz, Robert McConnell, Jonathon Sedlacek +4
We use a co-trapped ion () to sympathetically cool and measure the quantum state populations of a memory-qubit ion of a different atomic species ($^{40}\mathr…
Heralded multiphoton states with coherent spin interactions in waveguide QED
V Paulisch, A González-Tudela, H J Kimble +1
WaveguideQEDoffers the possibility of generating strong coherent atomic interactions either through appropriate atomic configurations in the dissipative regime or in the bandgap re…
Electric field cancellation on quartz: a Rb adsorbate induced negative electron affinity surface
J. A. Sedlacek, E. Kim, S. T. Rittenhouse +3
We investigate the (0001) surface of single crystal quartz with a submonolayer of Rb adsorbates. Using Rydberg atom electromagnetically induced transparency, we investigate the ele…
Collective state synthesis in an optical cavity using Rydberg atom blockade
Santosh Kumar, Jiteng Sheng, Jonathon A. Sedlacek +2
We investigate the coherent manipulation of interacting Rydberg atoms placed inside a high-finesse optical cavity for the deterministic preparation of strongly coupled light-matter…
Atom Based Vector Microwave Electrometry Using Rubidium Rydberg Atoms in a Vapor Cell
J. Sedlacek, A. Schwettmann, Harald Kübler +1
It is clearly important to pursue atomic standards for quantities like electromagnetic fields, time, length and gravity. We have recently shown, using Rydberg states, that Rb atoms…
Exploiting Rydberg Atom Surface Phonon Polariton Coupling for Single Photon Subtraction
H. Kübler, D. Booth, J. Sedlacek +2
We investigate a hybrid quantum system that consists of a superatom coupled to a surface phonon-polariton. We apply this hybrid quantum system to subtract individual photons from a…
