The most important part of any quantum computer are its quantum bits, or qubits. IonQ’s qubits are ionized ytterbium atoms, a silvery rare-earth metal. Each ytterbium atom is perfectly identical to every other ytterbium atom in the universe. ...

The ion trap, a device that confines ions within a confined space via electromagnetic fields, stands out as a highly promising candidate for the realization of large-scale quantum computing. However, the principal challenge in this approach is to simultaneously maintain stable ion trapping and precis...
Furthermore, the QCCD architecture has been used to implement high-fidelity quantum logic, and can be paired with laser-free gate schemes4,11,17. Recently, QCCD architectures have been used to demonstrate key steps towards the fault-tolerant operation of a trapped ion quantum computer11,18,19...

Every proposal for constructing a large-scale quantum computer has engineering challenges, and the QCCD ar- chitecture is no different. As described in the original paper, difficulties include: (1) constructing a device ca- pable of trapping a large number of small ion crystals, (2) ...
Prof. Luming Duan atTsinghua Universityhas recently achieved a significant breakthrough in the field of quantum simulation. For the first time, researchers realized the stable trapping and cooling of a two-dimensional crystal of up to 512 ions and performed a quantum simulation with 3...
We present a design for the experimental integration of ion trapping and superconducting qubit systems as a step towards the realization of a quantum hybrid system. The scheme addresses two key difficulties in realizing such a system: a combined microfabricated ion trap and superconducting qubit archit...
Atomic ions trapped in electromagnetic potentials have long been used for fundamental studies in quantum physics. Over the past two decades, trapped ions have been successfully used to implement technologies such as quantum computing, quantum simulation,
One-dimensional systems exhibiting a continuous symmetry can host quantum phases of matter with true long-range order only in the presence of sufficiently long-range interactions1. In most physical systems, however, the interactions are short-ranged, hindering the emergence of such phases in one dim...
