Recent years have witnessed an explosion of interest in quantum devices for the production,
storage, and transfer of energy. This Colloquium concentrates on the field of quantum …

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 …

Quantum decoherence plays a pivotal role in the dynamical description of the quantum-to-
classical transition and is the main impediment to the realization of devices for quantum …

Quantum technologies exploit entanglement to revolutionize computing, measurements, and
communications. This has stimulated the research in different areas of physics to engineer …

This Colloquium describes a new paradigm for creating strong quantum interactions of light
and matter by way of single atoms and photons in nanoscopic lattices. Beyond the …

Inherent symmetry of a quantum system may protect its otherwise fragile states. Leveraging
such protection requires testing its robustness against uncontrolled environmental …

We propose a general framework for studying two-dimensional (2D) topologically ordered
states subject to local correlated errors and show that the resulting mixed state can display …

Quantum computation features known examples of hardware acceleration for certain
problems, but is challenging to realize because of its susceptibility to small errors from noise …

We construct a new class of quantum error-correcting codes for a bosonic mode, which are
advantageous for applications in quantum memories, communication, and scalable …

Coherence refers to correlations in waves. Because matter has a wave-particle nature, it is
unsurprising that coherence has deep connections with the most contemporary issues in …
