We study the interaction of Rayleigh and shear horizontal surface acoustic waves (SAWs) with spin waves in thin Ni films on a piezoelectric LiTaO3 substrate, which supports both SAW modes
We study the interaction of surface acoustic waves (SAWs) with spin waves (SWs) in a Co40Fe40B20/Au/Ni81Fe19 system composed of two ferromagnetic layers separated by a nonmagnetic Au spacer layer.
We explore possibilities to efficiently create entanglement between multiple qubits by extending the standard gate set.
Magnonics addresses the physical properties of spin waves and utilizes them for data processing. Scalability down to atomic dimensions, operation in the GHz-to-THz frequency range, utilization of

WMI demonstrates a highly protected superconducting qubit as building block of a scalable quantum processor with strongly suppressed qubit coherence.
To control and measure the state of a quantum system, it must necessarily be coupled to external degrees of freedom. This inevitably leads to spontaneous emission via the Purcell effect,
Spray deposition is a scalable and cost-effective technique for the fabrication of magnetic hybrid films containing diblock copolymers (DBCs) and magnetic nanoparticles. However, it is challenging to
