Quantum information technology is a major disruptive innovation that impacts and reconstructs the traditional technology system. How to make students understand the basic principles of quantum information science and perform basic experimental practice in daily teaching has become a hot and difficult issue in the current physics experimental teaching.

Recently, Dr. Shiyun Zhou, an experimental instructor from the Department of Physics of Fudan University, Shanghai, China, and his student Zhengyang Zhao jointly published the research result of "Quantum Control Involved the NV-center in Diamond" in the journal Physics Experimentation. Based on the CIQTEK Diamond Quantum Computer for Education, the research results introduced the basic contents of quantum computing based on NV center in diamonds (initialization, regulation, and readout of quantum bits), designed and extended the teaching contents related to Rabi oscillation. 

Teaching Experiment
Quantum computing experiments are rich in theoretical content and difficult to operate. Successful completion of the experiment does not mean that students really understand its content. Therefore, it is necessary to discuss the teaching design and extension of quantum computing experimental contents. The researchers used CIQTEK Diamond Quantum Computer for Education as the basis for their quantum computing teaching experiments, which contain two parts.

a. Learning basic quantum regulation and understanding the basics of quantum computing, such as initialization, manipulation, and readout of quantum bits.
b. Conducting practical applications, students understand the superiority of quantum algorithms by implementing the classical quantum D-J algorithm

Based on teaching practices at Fudan University, the researchers focus on the teaching content and methods of the first part of the experiment, i.e., the quantum regulation part.

Experimental Extension
To better help students understand, the researchers designed and expanded the teaching content related to Rabi oscillation: through the Rabi oscillation experiment to understand the interaction between microwaves and spins, familiar with the initialization and readout of quantum states; discuss the effect of microwave frequency in the Rabi oscillation experiment, which leads to the method of measuring resonant frequency; measure the resonant frequency through the continuous wave experiment and discuss the effect of microwave duration parameters on the measurement results during the measurement process; change the position of the magnet, qualitatively demonstrate the system synthesis characteristics of the NV center, so that students understand how to perform parametric optimization in the actual instrument.

Through this teaching design, teachers can teach students heuristically, guide them to think actively, help them understand the principles and techniques of quantum modulation more comprehensively, and lay a good foundation for the further realization of quantum computing.

Quantum information science is an emerging science and technology formed by the cross-fertilization of physics, information science, and other disciplines, which has the characteristics of broad-based, cross-cutting, emphasis on research practice, and the combination of theory and experiment. Therefore, involving students in the experimental practice of quantum information science in daily teaching practice is of great value to help students fully understand the principles and techniques of quantum regulation, which is the foundation of quantum information science.

Introduction to the Journal of Physics Experimentation
Physics Experimentation was founded in 1980, which is an academic journal (Physics) under the supervision of the Ministry of Education and sponsored by Northeast Normal University, China, and is the journal of the Steering Committee for Teaching Physics and Astronomy of the Ministry of Education. It mainly publishes the results of physics experiments and exchanges new ideas, new methods, and new developments in physics experimental teaching reform.

CIQTEK Diamond Quantum Computer for Education | Focus on quantum information science experimental teaching
CIQTEK Diamond Quantum Computer for Education is a teaching instrument based on the spin magnetic resonance of nitrogen-vacancy (NV) center in diamond. By controlling basic physical quantities such as optics, electricity and magnetism, it implements quantum manipulation and readout of NV center spins, which enables the demonstration of basic concepts of quantum computing, such as qubits, quantum gates and quantum algorithms.
The instrument works at room temperature (no need for a cryogenic environment), making the operating cost almost zero. The desktop design makes it easy to adapt to classrooms, laboratories, and other environments for conducting quantum mechanics and quantum computing experimental courses.
