Subspace benchmarking high-fidelity entangling operations with trapped ions
Physical Review Research, 2020 We present a new and simplified two-qubit randomized benchmarking procedure that operates only in the symmetric subspace of a pair of qubits and is well suited for benchmarking trapped-ion systems.

Simulations of ion trapping in a micrometer-sized cylindrical ion trap [PDF]
Journal of the American Society for Mass Spectrometry, 2006 We have performed detailed SIMION simulations of ion behavior in micrometer-sized cylindrical ion traps (r0 = 1 microm). Simulations examined the effects of ion and neutral temperature, the pressure and nature of cooling gas, ion mass, trap voltage and frequency, space-charge, fabrication defects, and other parameters on the ability of micrometer-sized

Microfabricated ion traps [PDF]
Contemporary Physics, 2011 Ion traps offer the opportunity to study fundamental quantum systems with high level of accuracy highly decoupled from the environment. Individual atomic ions can be controlled and manipulated with electric fields, cooled to the ground state of motion with laser cooling and coherently manipulated using optical and microwave radiation.

Design of an Integrated Bell-State Analyzer on a Thin-Film Lithium Niobate Platform
IEEE Photonics Journal, 2022 Trapped ions are excellent candidates for quantum computing and quantum networks because of their long coherence times, ability to generate entangled photons as well as high fidelity single- and two-qubit gates. To scale up trapped ion quantum computing,

Optical trapping of an ion [PDF]
Nature Photonics, 2010 For several decades, ions have been trapped by radio frequency (RF) and neutral particles by optical fields. We implement the experimental proof-of-principle for trapping an ion in an optical dipole trap. While loading, initialization and final detection are performed in a RF trap, in between, this RF trap is completely disabled and substituted by the ...

Thermometry in a Multipole Ion Trap
Applied Sciences, 2020 We present a characterization of the ions’ translational energy distribution in a multipole ion trap. A linear mapping between the energy distribution of the trapped ions onto the ions’ time-of-flight (TOF) to a detector is demonstrated.

A high-fidelity quantum matter-link between ion-trap microchip modules
Nature Communications, 2023 A possible route to scalability of trapped-ion-based quantum computing platforms is to connect multiple modules where ions can be shuttled across different registers.

Modular cryostat for ion trapping with surface-electrode ion traps [PDF]
Review of Scientific Instruments, 2013 We present a simple cryostat purpose built for use with surface-electrode ion traps, designed around an affordable, large cooling power commercial pulse tube refrigerator. A modular vacuum enclosure with a single vacuum space facilitates interior access and enables rapid turnaround and flexibility for future modifications.

Nanofriction in cold ion traps [PDF]
Nature Communications, 2011 Sliding friction between crystal lattices and the physics of cold ion traps are so far non-overlapping fields. Two sliding lattices may either stick and show static friction or slip with dynamic friction; cold ions are known to form static chains, helices, or clusters, depending on trapping conditions.

Trapping of highly charged ions with an electrostatic ion trap [PDF]
Journal of Physics: Conference Series, 2009 In the current contribution, we present our first results with an electrostatic ion trap which has been constructed at LKB (Laboratoire Kastler Brossel) in collaboration with the Weizmann institute. The electrostatic ion trap is composed of two coaxial electrostatic mirrors, working for charged particles in the same way as a Fabry-Perot interferometer ...
