Experimental Methods for Trapping Ions Using Microfabricated Surface Ion Traps [PDF]
Journal of Visualized Experiments, 2017 Ions trapped in a quadrupole Paul trap have been considered one of the strong physical candidates to implement quantum information processing. This is due to their long coherence time and their capability to manipulate and detect individual quantum bits (qubits).

Sudden death and long-lived entanglement of two trapped ions [PDF]
, 2007 The dynamical properties of quantum entanglement in two effective two-level trapped ions interacting with a laser field are studied in terms of the negative eigenvalues of the partial transposition of the density operator. In contrast to the usual belief

Molecular Oncology, EarlyView.We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Engineering Dynamically Decoupled Quantum Simulations with Trapped Ions
PRX Quantum, 2023 An external drive can improve the coherence of a quantum many-body system by averaging out noise sources. It can also be used to realize models that are inaccessible in the static limit, through Floquet Hamiltonian engineering. The full possibilities for

Electronic spectroscopy of cold cations in a 22-pole trap by indirect methods [PDF]
, 2013 The confining capabilities of a 22-pole ion trap have been employed to mea- sure electronic spectra of cations of astrophysical relevance. The ion trap sits on the head of a closed cycle cryostat, enabling collisional cooling of the confined ions with

Interpreting the effects of DNA polymerase variants at the structural level
Molecular Oncology, EarlyView.Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

Driven geometric phase gates with trapped ions
New Journal of Physics, 2013 We describe a hybrid laser–microwave scheme to implement two-qubit geometric phase gates in crystals of trapped ions. The proposed gates can attain errors below the fault-tolerance threshold in the presence of thermal, dephasing, laser-phase and ...

Ultra-fast two-qubit ion gate using sequences of resonant pulses
New Journal of Physics, 2020 We propose a new protocol to implement ultra-fast two-qubit phase gates with trapped ions using spin-dependent kicks induced by resonant transitions. By only optimizing the allocation of the arrival times in a pulse train sequence the gate is implemented

Laser-Cooled Ion Beams and Strongly Coupled Plasmas for Precision Experiments [PDF]
, 2008 The first part of this thesis summarizes the results of laser-cooling of relativistic C3+ ion beams at the ESR/GSI. It is shown that laser cooling at high beam energies is feasible and that momentum spreads much smaller than those observed for electron ...
