In a new publication in Nature Materials, an international team of researchers has developed groundbreaking artificial chains ...

Quantum state transfer, whereby quantum information is conveyed between distinct physical locations without compromising inherent quantum properties, is fundamental to the advancement of quantum ...

For the homogeneous Heisenberg chain, the researchers used the nanographene molecule Olympicen, which consists of five carbon rings. In 2024, Empa researchers and their partners successfully for the ...

Frustrated quantum spin chains are one-dimensional systems in which competing interactions between adjacent and next-nearest-neighbour spins inhibit the establishment of conventional magnetic order.

The rapid progress of quantum simulators is now enabling them to study problems that before have been limited to the domain of theoretical physics and numerical simulation. A team of researchers at ...

Neutron scattering is considered the method of choice for investigating magnetic structures and excitations in quantum materials. Now, for the first time, the evaluation of measurement data from the ...

This ambiguity should give quantum computers true “superpowers”. At least in theory, quantum-based computers can perform calculations in fractions of a second that stump today's best supercomputers.

In these chains, the magnetic moments align in an antiparallel manner but do not completely cancel out. Also of great interest are two-dimensional spin lattices, which exhibit a much greater variety ...
