What is quantum coherence?

We say a message is incoherent when we can't make it out, or when it doesn't make sense. A scribbled note, a drunken argument or a conversation taking place five tables down in a crowded cafe might ...
In a novel experiment, physicists have observed long range quantum coherence effects due to Aharonov-Bohm interference in a topological insulator-based device. This finding opens up a new realm of ...
Scientists have hypothesized that moir excitons -- electron-hole pairs confined in moir interference fringes which overlap with slightly offset patterns -- may function as qubits in next-generation ...
Duality ellipse The amount of coherence is linked to the amount of waveness and particleness of a quantum system through an duality ellipse relation. The coherence, modulated by the object shape, can ...
Researchers at Rice University have made a groundbreaking discovery in the field of quantum physics, unveiling a powerful quantum interference effect. This significant advancement involves ...
Scientists work to sync up quantum objects for high-resolution sensing and complex computation. (Nanowerk News) We say a message is incoherent when we can’t make it out, or when it doesn’t make sense.
