View MoreQuantum 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 ExperimentQuantum 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 algorithmBased 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 ExtensionTo 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 co...

CIQTEK is pleased to sponsor this award to scientists who have contributed significantly to electron paramagnetic resonance (EPR or ESR) research. This time, congratulations to Dr. Shen Zhou from the National University of Defense Technology, Dr. Sergey Veber from the International Tomography Center of SB RAS, and Dr. Zhiyuan Zhao from the University of Science and Technology of China for winning the awards.APES 2022, Webinar, November 4-7, 2022CIQTEK is happy to sponsor the APES 2022 during November 4-7, 2022. The symposium this year is an online event for international speakers and participants, a new start for Asia-Pacific EPR/ESR Society in the post-epidemic era. The main aims of APES 2022 are to bring together EPR/ESR spectroscopists and to promote and facilitate collaboration among the EPR/ESR community. APES 2022 is intended to stimulate discussions on the forefront of research in all aspects of EPR/ESR ranging from theoretical and experimental advances in CW/Pulsed EPR, high frequency, and high field EPR, ENDOR, PEDLOR/DEER, time-resolved EPR, FMR, MRI, ODMR to applications in medicine, biology, chemistry, materials science and nanotechnology.On November 5, Dr. Shen Zhou gave a report entitled "Quantum Computing with Multi-levelled Endohedral Fullerene Qudits".Abstract of the PresentationParamagnetic fullerenes, such as fullerenes, have been proposed as a chemical way of implementing quantum information applications, due to their long spin coherence time. Moreover, the S>1/2 system provides a new way of tackling the scalability issue, by directly embedding qudit (d is the dimension of the quantum system). However, the addressability of the individual electron spin levels was not easy. Using molecular engineering, the degeneracy of transitions between different mS states can be lifted by zero-field splitting effects, so that the multiple electron spin transitions are differentiable. We started the multilevel study by observing quantum phase interference in a three leveled spin system of photoexcited C70. Then, the quantum geometric phase manipulation, which has long been proposed for the advantages of error tolerance and gating speed, was implemented in a pure electron spin system using N@C60 derivatives for the first time. To further make use of the abundant energy levels in the paramagnetic fullerene system, the hyperfine interactions were harnessed to perform quantum manipulations in a multi-processing manner via the three parallel channels. When the same operations were applied to the multi-processes, error corrected Deutsch-Jozsa (D-J) algorithm has been achieved. Different operations were also managed to be applied parallelly, demonstrating the multi-task ability of this molecular qudit system.Biography of Dr. Shen ZhouMy name is Shen Zhou, and I am now an associate pro...

At the 12th Asia-Pacific EPR/ESR Symposium (APES 2022), the CIQTEK Sponsored Young Scientist Award was awarded to Dr. Fei Kong, CAS Key Laboratory of Microscale Magnetic Resonance and School of Physical Sciences, University of Science and Technology of China.As winner of the 2022 competition, Dr. Fei Kong was invited to gave a prize lecture, "Zero-field EPR spectroscopy based on quantum sensors", at the conference, on November 6th.APES 2022, Webinar, November 4-7, 2022CIQTEK is happy to sponsor the APES 2022 during November 4-7, 2022.

Methods 15, 697–699 (2018)]. A key figure of single-molecule EPR is that it can resolve heterogeneous molecular information, which is averaged in conventional EPR measurement. However, the current single-molecule measurements are insufficient to do so, due to the poor spectral resolution. Here, I will introduce an easy way to substantially improve the spectral resolution, i.e., removing the magnetic field. The zero-field EPR has been well-studied for decades [Chem. Rev. 83, 49–82 (1983)]. It has narrower spectra with the tradeoff of much poorer sensitivity. Difference from conventional inductive detection, the signal of NV-EPR comes from the statistical fluctuation rather than the thermal polarization of spins, which does not depend on the magnetic field. Therefore, the NV center is an ideal sensor for zero-field EPR detection. I will show that the NV-EPR has the advantage in not only spatial resolution but also spectral resolution.Biography of Dr. Fei KongDr. Fei Kong was born in Hefei, China. In 2012 he obtained a B.Sc. degree at the University of Science and Technology of China (USTC) and later undertook experimental research there on quantum control and quantum simulation using nitrogen-vacancy centers in diamond with Prof. Dr. Jiangfeng ...
