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 …

Trapped-ion quantum information processors store information in atomic ions maintained in
position in free space by electric fields. Quantum logic is enacted through manipulation of …

Midcircuit operations, such as qubit state measurement or reset, are central to many tasks in
quantum information science, including quantum computing, entanglement generation, 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 …

Rydberg atoms, with their enormous electronic orbitals, exhibit dipole–dipole interactions
reaching the gigahertz range at a distance of a micrometre, making them a prominent …

A long-time quantum memory capable of storing and measuring quantum information at the
single-qubit level is an essential ingredient for practical quantum computation and …

Frustration, or the competition between interacting components of a network, is often
responsible for the emergent complexity of many-body systems. For instance, frustrated …

Remarkable progress towards realizing quantum computation has been achieved using
natural and artificial atoms as qubits. This paper presents a brief overview of the current …

We study the quantum dynamics of a two-level system interacting with a quantized harmonic
oscillator in the deep strong coupling regime (DSC) of the Jaynes-Cummings model, that is …

We use electronic microwave control methods to implement addressed single-qubit gates
with high speed and fidelity, for Ca+ 43 hyperfine “atomic clock” qubits in a cryogenic (100 …
