Quantum Markov semigroups provide a rigorous mathematical framework for describing the time‐continuous evolution of open quantum systems. These semigroups encapsulate the interplay between coherent ...

Giant atoms, artificial atoms larger than the interacting wavelength of light, exhibit decoherence-free behavior, but what ...

Quantum entanglement has shifted from a philosophical puzzle to a design brief for engineers working at the scale of atoms, ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

The qubit state decays toward the "north pole" of the sphere due to decoherence. Using the study's coherence-stabilized sensing protocol, the researchers temporarily counteracted the decay, leading to ...

The demonstration of the first antimatter quantum bit paves the way for substantially improved tests of nature’s fundamental symmetries. Particles such as the antiproton, which has the same mass but ...
