Physicists at the University of Konstanz have developed a method to use light to alter the magnetic properties of common crystals like hematite in a non-thermal way, enabling high-speed data processing and quantum research at room temperature, potentially revolutionizing information technology and quantum studies.
Researchers have successfully created a strong coupling between magnons and phonons in a thin film at room temperature, using shear sound waves to link ultrasound and magnetic waves. This breakthrough could lead to the development of hybrid wave-based devices for information processing with minimal losses, potentially opening the door for exciting progress in information and communication technologies. The key element enabling this work was a nano-structured surface acoustic wave resonator, which enhanced shear sound waves and allowed for a strong coupling between surface sound waves and magnets in the resonator.
Scientists at HZDR in Germany have developed a new method for transmitting quantum information using the magnetism of magnons, addressing the need for efficient information transmission within quantum networks, which is crucial for the advancement of quantum computing technology.
Researchers at HZDR have manipulated atomic-sized qubits in silicon carbide using wave-like excitations in magnetic disks called magnons, presenting a new approach for transducing quantum information. This method could potentially enable the transduction of information within quantum networks, addressing the need for efficient communication between distinct quantum modules. The team's research demonstrates the feasibility of addressing qubits exclusively with magnons, offering insights for the development of a practical quantum computer in the future.
Researchers at the University of Manitoba have developed a highly performing device based on cavity magnon polaritons that can emit and amplify microwaves. This device significantly outperforms previously proposed solid-state devices for coherent microwave emission and amplification at room temperature. The new gain-driven polariton realized by the researchers could open exciting new possibilities for the development of highly performing solid-state microwave sources that can be integrated on-chip. These polariton microwave sources are frequency tunable due to the fabulous controllability of light-matter interaction and could ultimately be integrated in a broad range of technologies and devices, including wireless communication systems and quantum computers.
