For quantum computers to successfully solve real-world problems, it is necessary to tackle
the challenge of noise: the errors that occur in elementary physical components due to …

Quantum circuits—built from local unitary gates and local measurements—are a new
playground for quantum many-body physics and a tractable setting to explore universal …

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 …

Colloidal quantum dots (QDs) are nanoscale semiconductor crystals with surface ligands
that enable their dispersion in solvents. Quantum confinement effects facilitate wave function …

In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

The second quantum revolution has been built on a foundation of fundamental research at
the intersection of physics and information science, giving rise to the discipline we now call …

Exceptional points (EPs) correspond to degeneracies of open systems. These are attracting
much interest in optics, optoelectronics, plasmonics, and condensed matter physics. In the …

Optical atomic clocks represent the state of the art in the frontier of modern measurement
science. In this article a detailed review on the development of optical atomic clocks that are …

In quantum physics, measurements can fundamentally yield discrete and random results.
Emblematic of this feature is Bohr's 1913 proposal of quantum jumps between two discrete …

Atomic clocks based on optical transitions are the most stable, and therefore precise,
timekeepers available. These clocks operate by alternating intervals of atomic interrogation …
