How a superfluid simultaneously becomes a solid

In everyday life, all matter exists as either a gas, liquid, or solid. In quantum mechanics, however, it is possible for two distinct states to exist simultaneously. An ultracold quantum system, for instance, can exhibit the properties of both a fluid and a solid at the same time.

A low-cost protocol enables preparation of magic states and fault-tolerant universal quantum computation

Quantum computers, systems that perform computations leveraging quantum mechanical effects, could outperform classical computers in some optimization and information processing tasks. As these systems are highly influenced by noise, however, they need to integrate strategies that will minimize the errors they produce.

MRI technology inspires quantum advancement with 2D materials

The same technology behind MRI images of injury or disease also powers nuclear magnetic resonance (NMR) spectroscopy, which is used to analyze biological molecules for research on diseases and therapeutics. While NMR spectroscopy produces valuable data about the structure of molecules, the resolution is too low to sense individual atoms.

Novel approach suppresses magnetic noise for the fast optical control of a coherent hole spin in a microcavity

Quantum technologies, devices that work by leveraging quantum mechanical effects, could outperform classical technologies in some fields and settings. The so-called spin (i.e., intrinsic angular momentum) carried by quantum particles is central to the functioning of quantum systems, as it can store quantum information.

Symmetry-based Floquet optical selection rules help explain light-induced sidebands

Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD), in collaboration with international partners, have developed momentum-resolved Floquet optical selection rules. They show how these symmetry-based rules determine the spectral weight distributions of photon-dressed sidebands in time- and angle-resolved photoemission spectroscopy (TrARPES) experiments across different pump-probe configurations. This fundamental work […]

Overcoming disordered energy in light-matter interactions

Polaritons are formed by the strong coupling of light and matter. When they mix together, all the matter is excited simultaneously—referred to as delocalization. This delocalization has the unique ability to relay energy between matter that is otherwise not possible.
