Generation and manipulation of magnonic Schrödinger cat states for quantum information science
With the rapid accumulation of information in modern society, it becomes more and more important to find efficient means to store and process big data. Traditional electronic devices suffer from the problems of large energy consumption and Joule heating. To overcome these problems, spintronics and quantum information sciences rise in the last few decades and have shown great potential to innovate our computing technologies. This project investigates the interplay of spintronics and quantum information and aims to take advantage of both fields to build a hybrid quantum system for studying exotic quantum phenomena and for performing multi-functional quantum information tasks. The major issues of this interdisciplinary field are how to generate, manipulate and detect the robust quantum state of spins and further entangle it to the existing quantum platforms, for example, photons, phonons, and qubits, as shown in the figure attached. Under this background, we set the objectives of our project as follows: (1) Identify the generation, manipulation, and decoherence channels of magnon quantum states including single magnon states, squeezed states, and Schrodinger cat states. (2) Build a theoretical framework to study the dynamics of magnon quantum states, taking the decoherence effects of magnons into account. (3) Propose new methods and materials to control the magnon quantum states and their applications in quantum information. (4) Set up the framework of quantum magnonics and disseminate the field to a wide community. Note that we are in the stage of the second quantum revolution that people are using basic principles of quantum mechanics to innovate our computing, simulation, and teleportation technologies. European has launched the well-known Quantum Technologies Flagship, and the Netherlands launched the Quantum Delta Program to build an excellent quantum ecosystem. The successful realization of my project will first strengthen the fundamental aspects of quantum information using hybrid quantum systems based on magnonic platforms. Further, it can bring considerable added value to the application of solid-state platforms for quantum computing, quantum communication, and quantum simulation and thus extend the current horizon of spintronics and quantum information science.

Project objective
Given the rapid development of information-based society, it becomes more important and urgent to find efficient means to store and process huge amount of information. While the traditional transistor technology is becoming a bottleneck, spintronics and quantum information science stand out as two promising candidates to innovate our current computing and storage concepts. The combination of these two fields can allow us to take advantages of both fields to build solid-state platforms for studying quantum phenomena and performing multi-functional quantum information tasks. However, their interaction was limited because of the different properties of classical magnetization in spintronics and quantum qubit in the quantum information. The situation is changing with the progress of magnonic spintronics, which manipulates the collective magnetic excitation so-called magnons, and fits neatly with continuous variable quantum information. In the SPINCAT project, I will provide a route to bridge the two fields by examining the generation and manipulation of the magnonic Schrödinger cat state in the continuous variable quantum information science. In particular, I will (i) generate and manipulate of magnonic cat state in magnetic ordered systems driven by parametric pumping, (ii) ascertain its robustness under the influence of magnon-photon and magnon-magnon scattering, (iii) detect this nonclassical state by coupling it to the cavity photons, and (iv) identify its applications in quantum computing and quantum teleportation. The SPINCAT is an original, novel and highly interdisciplinary project covering spintronics, quantum optics and quantum information. The successful implementation of this project will significantly broaden the horizon of each subfield, and fertilize the on-going topics in magnonic spintronics in particular. Further, the training and skills acquired in this project would increase my competence in academics and boost myself to become a mature researcher.
