A quantum internet is the holy grail of quantum information processing, enabling the
deployment of a broad range of quantum technologies and protocols on a global scale …

It is for the first time that quantum simulation for high-energy physics (HEP) is studied in the
US decadal particle-physics community planning, and in fact until recently, this was not …

We report on an elementary quantum network of two atomic ions separated by 230 m. The
ions are trapped in different buildings and connected with 520 (2) m of optical fiber. At each …

In this short review article, we aim to provide physicists not working within the quantum
computing community a hopefully easy-to-read introduction to the state of the art in the field …

Trapped ions are among the most promising systems for practical quantum computing (QC).
The basic requirements for universal QC have all been demonstrated with ions, and …

Realizing a long coherence time quantum memory is a major challenge of current quantum
technology. Until now, the longest coherence-time of a single qubit was reported as 660 s in …

Quantum networks play an extremely important role in quantum information science, with
application to quantum communication, computation, metrology, and fundamental tests. One …

The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

Photons at microwave and optical frequencies are principal carriers for quantum information.
While microwave photons can be effectively controlled at the local circuit level, optical …

We demonstrate remote entanglement of trapped-ion qubits via a quantum-optical fiber link
with fidelity and rate approaching those of local operations. Two Sr+ 88 qubits are entangled …
