INMA Impulso: Akashdeep Kamra
INMA Impulso seminar: Quantum Magnonics: Exploiting niches of magnets for quantum materials and computing
On Wednesday 27 September will take place a new session of the INMA Impulso conference series, a series of conferences that seeks to bring the most cutting-edge research to society.
The next session entitled: “Quantum Magnonics: Exploiting niches of magnets for quantum materials and computing” will be given by Akashdeep Kamra, from the Autonomous University of Madrid, IFIMAC – Condensed Matter Physics Center.
Summary of the talk:
Several unique properties of light/photons have enabled generation and manipulation of optical fields in “nonclassical” states resulting in crucial contributions to quantum information and gravitational waves detection, among other research areas. Owing to the similar, bosonic nature of both photons and magnons – the spin excitations of ordered magnets, much can be learned about spin transport and dynamics in magnetic insulators from the relatively mature field of quantum optics.
In this talk, we will discuss how concepts, such as Heisenberg uncertainty principle, provide crucial novel insights into the quantum properties of magnons and show the latter’s niche over photons in several regards. Focusing on the role of squeezing, we will see how anisotropic ferromagnets and Heisenberg antiferromagnets admit spontaneously squeezed excitations. The resulting quantum fluctuations enable magnons to couple strongly with other excitations and imbue them with an intrinsic entanglement. We will conclude with two examples on how these fresh insights open new avenues for exploiting magnetic insulators towards quantum computing technologies by interfacing these squeezed-magnons with spin qubits.
The INMA Impulso seminars are organised by the Instituto de Nanociencia y Materiales de Aragón (INMA), a joint institute of the CSIC and the University of Zaragoza.
The conference will take place on Wednesday 27 September at 12 noon in the Seminar of Theoretical Physics (above the Condensed Matter Physics corridor) of the Faculty of Sciences of the University of Zaragoza.
