Coherent Gate Operations in Hybrid Magnonics

Area of Science:

• Physics
• Quantum Information Science
• Materials Science

Background:

• Electromagnonics, the interplay of spin excitations and electromagnetic waves, shows potential for coherent information processing.
• A key challenge in hybrid magnonics is the absence of real-time manipulation methods for system dynamics.

Purpose of the Study:

• To introduce a novel technique for fast and uniform modulation in hybrid magnonics.
• To demonstrate benchmark coherent gate operations using this new method.

Main Methods:

• Implementation of a fast and uniform modulation technique.
• Demonstration of semiclassical analogies of Landau-Zener transitions.
• Observation of Rabi oscillations and Ramsey interference.
• Execution of controlled mode swap operations.

Main Results:

• Successful demonstration of various coherent gate operations in hybrid magnonics.
• Validation of the technique's efficacy for real-time dynamical manipulation.
• Establishment of a foundational method for controlling coherent signals.

Conclusions:

• The developed modulation technique provides a powerful tool for dynamical control in hybrid magnonics.
• This approach paves the way for advanced coherent information processing.
• The method is potentially generalizable to diverse applications.
