Is There a New Quantum Computing Platform? Artificial Materials that Look Like Natural Materials Rare Earth Compounds with Quantum Entanglements.

Researchers have created a macroscopic quantum entangled state that mimics rare earth elements by mixing two-dimensional materials.

Physicists have developed a novel ultra-thin two-layer material that has quantum features generally associated with rare earth compounds. This material, which is reasonably inexpensive to manufacture and does not contain rare earth metals, could provide a new platform for unconventional superconductivity and quantum criticality research.

The researchers demonstrated that a completely new quantum form of matter can emerge from seemingly conventional materials. The breakthrough came as a result of their efforts to build a quantum spin liquid that could be used to study emergent quantum phenomena like gauge theory. This procedure includes synthesizing a single layer of atomically thin tantalum disulfide, but it also makes two-layer islands.

When the researchers looked at these islands, they discovered that interactions between the two layers caused the Kondo effect, which resulted in a macroscopically entangled state of matter that produced a heavy-fermion system.

Viliam Vao and colleagues developed a new ultra-thin two-layer material with quantum features that would ordinarily necessitate the use of rare earth elements. This material has the potential to improve quantum computers and promote quantum criticality and superconducting studies. Vao shares the narrative of how this discovery came to be in this interview.

The Kondo effect occurs when magnetic impurities and electrons interact, causing the electrical resistance of a material to fluctuate with temperature. Because the electrons behave as if they have more mass as a result, these compounds are known as heavy fermion materials. Materials containing rare earth elements are prone to this phenomena.

Heavy fermion materials are significant in a variety of cutting-edge physics fields, including quantum materials research. “The features of naturally occurring chemicals make it difficult to study complicated quantum materials.” Professor Peter Liljeroth states, “Our goal is to create artificial designer materials that can be easily tweaked and controlled externally to increase the variety of strange phenomena that can be generated in the lab.”

Heavy fermion materials, for example, could act as topological superconductors, which could be useful for constructing qubits that are more resistant to noise and environmental disruption, lowering quantum computer error rates. “Having a heavy fermion material system that can be easily included into electrical devices and tweaked would be extremely helpful in realizing this… Summary of the latest news from Brinkwire.
