More than 100 years ago, Hertz succeeded in transmitting signals over a few metres to a receiving antenna using an electromagnetic oscillator, thus proving the electromagnetic theory developed by Maxwell. Since this seminal work, technology has developed, and various oscillators are now available at the quantum mechanical level. For quantized electromagnetic oscillations, atoms in cavities can be used to couple electric fields. However, a quantum mechanical link between two mechanical… 
Microwave quantum logic gates for trapped ions
TLDR
The approach, which involves integrating the quantum control mechanism into the trapping device in a scalable manner, could be applied to quantum information processing, simulation and spectroscopy.
Coupled quantized mechanical oscillators
TLDR
This work implements direct controllable coupling between quantized mechanical oscillators held in separate locations through the mutual Coulomb interaction of two ions held in trapping potentials separated by 40 μm, establishing that direct coherent motional coupling is possible for separately trapped ions.
An optical-fiber interface to a trapped-ion quantum computer
TLDR
This work demonstrates the integration of an optical fiber with a planar ion trap, and shows the physical interaction between fiber light and the trapped-ion qubit, and quantifies the perturbative effects of the fiber dielectric on ion trap operation.
Experimental quantum simulations of many-body physics with trapped ions.
TLDR
An overview of different trapping techniques of ions as well as implementations for coherent manipulation of their quantum states and current approaches for scaling up to more ions and more-dimensional systems are given.
Dipole–dipole interaction between trapped two-level ions interacting with a quantized field in the Lamb–Dicke regime
To achieve more accuracy in a system containing N trapped two-level ions interacting with a single-mode quantized field, in this paper we will consider the dipole–dipole interaction (DDI) between the
Sympathetic cooling of a trapped proton mediated by an LC circuit
Efficient cooling of trapped charged particles is essential to many fundamental physics experiments1,2, to high-precision metrology3,4 and to quantum technology5,6. Until now, sympathetic cooling has

Scalability is a challenging yet key aspect required for large scale quantum computing and simulation using ions trapped in radio-frequency (rf) Paul traps. In this thesis 171Yb+ ions are used to
Quantum Parametric Oscillator with Trapped Ions.
TLDR
The Coulomb interaction between two trapped ions is exploited to achieve strong nonlinear coupling between normal modes of motion at the single-phonon level and this coupling is applied to directly measure the parity and Wigner functions of the ions' motional states.

A trapped single ion inside a Bose–Einstein condensate

This work investigates whether atomic quantum gases and single trapped ions can be advantageously combined into one hybrid system, by exploring the immersion of a single trapped ion into a Bose–Einstein condensate of neutral atoms.
Quantum jumps of light recording the birth and death of a photon in a cavity

An experiment in which quantum jumps in the photon number are observed and a similar QND procedure to mesoscopic fields with tens of photons is applied, which should open new perspectives for the exploration of the quantum-to-classical boundary.

A model for an ion trap quantum computer that combines scalability (a feature usually associated with solid state proposals) with the advantages of quantum optical systems (in particular, quantum control and long decoherence times) is proposed.
