Physicists at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg have discovered a striking new form of quantum behavior. In star-shaped Kagome crystals—named after a ...

A theoretical study introduces three convex measures of dynamical coherence for quantum channels, built on channel ...

Aalto spinout Coherence Quantum raises €2.78M and tells in an exclusive interview how it plans to cut the heat and wiring ...

For years, researchers have tried various ways to coax quantum bits—or qubits, the basic building blocks of quantum computers—to remain in their quantum state for ever-longer times, a key step in ...

Figure 1: To grasp the principal result of Niu and colleagues’ research, consider a device that raises a suspended weight in Earth’s gravitational field. Since both work and coherent ergotropy are ...

Quantum coherence and decoherence are fundamental indications of how well a system of quantum objects -- atoms or other quantum particles -- maintains its relationships and how reliably the ongoing ...

Excitons are particle-like entities that form when electrons bind to electron vacancies called holes. A long-standing goal in condensed-matter physics is the unambiguous creation of a collective ...
