Researchers created a new quantum state of matter, dubbed a higher-order topological magnet, that may address key issues in quantum technology.
When different quantum states combine, new collective states of matter can emerge. In the quantum realm, combining components such as atoms that possess quantum effects can give rise to macroscopic quantum states of matter, featuring exotic quantum excitations that do not exist anywhere else.
'Creating a many-body topological quantum magnet makes it possible to explore an exciting new direction in physics. Excitations in topological quantum magnets have wildly different properties than those found in conventional magnets and could allow us to create new physical phenomena that are beyond the capabilities of current quantum materials,' Lado says.
'Topological quantum excitations, such as those realized in the topological quantum magnet we now built, can feature substantial protection against decoherence. Ultimately, the protection offered by these exotic excitations can help us overcome some of the most pressing challenges of currently available qubits,' Lado says.
