Microfabrication of an 8-qubit processor chip for a trapped-ion quantum computer demonstrator

Micro and Nano Engineering
Multilayer surface-electrode ion traps provide a scalable platform for quantum processors. In this paper we present a demonstrator chip designed to implement an 8-qubit shuttling-based quantum processor with chip-integrated microwave control for quantum ...

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

Advanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

Structural Transitions and Melting of Two-Dimensional Ion Crystals in RF Traps

Entropy
We investigate the structural properties and melting behaviors of two-dimensional ion crystals in an RF trap, focusing on the effects of ion temperature and trap potential symmetry. We identify distinct crystal structures that form under varying trapping

Octupolar perturbation of a single ion Penning trap

, 2003
The classical dynamics of a single ion, trapped in a Penning trap perturbed by a octupolar electrostatic perturbation, was investigated. The Penning trap provided three-dimensional trapping of charged particles by means of a magnetic field plus a ...

Quantum entanglement of ions for light dark matter detection

Journal of High Energy Physics
A detection scheme is explored for light dark matter, such as axion dark matter or dark photon dark matter, using a Paul ion trap system. We first demonstrate that a qubit, constructed from the ground and first excited states of vibrational modes of ions

Calibration of an audio-frequency ion trap mass spectrometer

, 2002
A method for calibration of an audio-frequency (AF) ion trap mass spectrometer is described. The method is proposed to surmount the obstacle that there is a lack of a proper calibrant for mass spectrometers in the mass-to-charge ratio (m/z) range of 10(6)

Ion trap quantum computing [PDF]

, 2011
Richard Feynman first proposed the idea of quantum computers thirty years ago. Since then, efforts have been undertaken to realize large-scale, fault-tolerant quantum computers that can factor large numbers much more quickly than classical computers ...
