Margaret Harris, the editor of the industry section of Physics World, tweeted (@DrMLHarris) about a Chinese "quantum couple", Dr. Yingqiu Dai and Dr. Zhifu Shi. As the first and third authors respectively, they published an important scientific achievement: based on the experimental results using CIQTEK X-band pulse electron paramagnetic resonance (EPR or ESR) spectroscopy EPR100, they improved the coherence time of quantum bits to 1.4 ms and increased the quality factor of quantum bits by 40 times! The editor of Physics World, Isabelle Dumé, reported the scientific achievements of the Key Laboratory of Microscopic Magnetic Resonance, Chinese Academy of Sciences, in the direction of molecular quantum bits research under the title "Molecular qubits stick around for longer". This major breakthrough was published in the authoritative academic journal, Chinese Physics Letters, under the title of "Experimental Protection of the Spin Coherence of a Molecular Qubit Exceeding a Millisecond", and attracted wide attention in the academic field. - Link to the paper in Chinese Physics Letters (Yingqiu Dai, Yue Fu, Zhifu Shi et al 2021 Chin. Phys. Lett. 38 030303): http://cpl.iphy.ac.cn/10.1088/0256-307X/38/3/030303 - Link to Physics World report: https://physicsworld.com/a/molecular-qubits-stick-around-for-longer It is worth mentioning that the CIQTEK X-band pulse EPR (ESR) spectroscopy EPR100 used in the experiment was designed by Dr. Yingqiu Dai's fiancé, Dr. Zhifu Shi. Dr. Yingqiu Dai and Dr. Zhifu Shi were using CIQTEK EPR100 for scientific research "CIQTEK X-band pulsed EPR (ESR) spectrometer plays a crucial role in the research process. Traditional commercial scientific instruments, affected by parameters such as the phase stability of the amplifier and the maximum number of pulses, cannot meet the needs of the experimental protocol. So the research team improved on the existing EPR spectrometer technology in the laboratory and completed the independent development of an arbitrary sequence generator, microwave pulse amplifier, and other components to complete a brand new X-band pulsed EPR (ESR) spectrometer that meets the experimental requirements. The final instrument can generate more than 10,000 high-precision pulse sequences with an accuracy of 50 ps, generating high-phase stability and high-intensity microwave pulses acting on quantum bits to finally complete the work." Dr. Zhifu Shi said. Extended Coherence Time Allows Quantum Technology to be Used More Widely In recent years, quantum computing has become a revolutionary technology. By taking advantage of the superposition and entanglement of quanta, quantum computers can accomplish in just a few seconds what classical computers cannot do in years for some specific scientific problems. And the longer the coherence time of quantum bits, the stronger the performance of...
View MoreQuantum technology has been developed and popularized, eventually bringing human society into the quantum era. On December 22, 2020, Xishan Senior High School in Jiangsu, China officially started the "Quantum Computing Theory and Experiment" course based on CIQTEK Diamond Quantum Computer for Education. This is the first time quantum computing has been introduced into Chinese primary and secondary schools, and it is another breakthrough for the quantum computing industry. Dr. Ming Chen from CIQTEK was explaining quantum computing to the students "The first channel is the laser, the third channel is the measurement, you need to pay attention to the state of each channel." Under the guidance of Dr. Ming Chen from CIQTEK, the students conducted Rabi oscillation experiments using the "Diamond Quantum Computing Teaching Machine". The students said, "It was fun to do quantum computing experiments with my classmates! This class allowed me to be exposed to cutting-edge technology during my high school years, which laid the foundation for my future major choice." Unlike Newton's classical theory, which emphasizes "certainty", "mechanics", and "uniqueness", quantum theory emphasizes "unmeasured ", "not unique", "interaction". The interaction between people in real life, the social state of one person with many faces, is obviously more consistent with quantum theory. Teaching the quantum theory way of thinking to children will allow them to quickly integrate into the forefront of world development. Countries around the world are gradually front-loading quantum teaching. In the United States, quantum computing education has been written into the National K12 Education Act, and in Europe, activities such as quantum computing basic education and quantum science summer camps are prevalent. Students experimenting on the CIQTEK Diamond Quantum Computer for Education CIQTEK Vice President Feng Zedong introduced, CIQTEK Diamond Quantum Computer for Education includes a series of courses on the basic theory of quantum computing, development history and experimental exploration, etc. The experimental part contains continuous wave experiments, Rabi oscillation experiments, echo experiments, T2 experiments, DJ experiments, etc. Students will experience the differences between quantum computing and ordinary computing, and explore the applications of quantum computing in new drug research, big data algorithms, password cracking and other fields. CIQTEK Diamond Quantum Computer for Education The Diamond Quantum Computer for Education is a teaching instrument based on the principle of NV-center and spin magnetic resonance in diamond, which can quantum manipulate and read out the spins of NV-center by controlling physical quantities such as laser, microwave, and magnetic field, so as to achieve quantum computing function.Based on this instrument, CIQTEK can provide overall solutions for quantum computing ...
View MoreProf. Dr. Jiangfeng Du and Prof. Dr. Fazhan Shi Team of the Chinese Academy of Sciences (CAS) Key Laboratory of Microscopic Magnetic Resonance, in collaboration with Dr. Xiaodong Wu of the University of Iowa, US, have made new progress in quantum precision measurement of the diamond nitrogen-vacancy (NV) center system. Using a deep-learning neural network approach, the two-dimensional nanoscale NMR spectra based on diamond quantum precision measurement were accelerated and the detection efficiency was improved by nearly an order of magnitude. The research results, entitled "Artificial intelligence enhanced two-dimensional nanoscale nuclear magnetic resonance spectroscopy" were published in the September 2020 issue of npj Quantum Information [npj Quantum Information 6, 79 (2020)]. Link to the article: https://www.nature.com/articles/s41534-020-00311-z The analysis of molecular structures of substances is an important tool for studying the properties and functions of substances in chemistry and life sciences. Nuclear magnetic resonance (NMR) is widely used in structural biology and clinical medicine because of its advantages such as non-destructive, physiological conditions, and even in situ detection. Traditional NMR techniques are limited by signal collection methods and can only measure the collective signals generated by more than billions of molecular systems. In recent years, nanomagnetic resonance spectroscopy has been realized based on diamond NV center. The CAS Key Laboratory of Microscopic Magnetic Resonance has achieved the first nanoscale two-dimensional NMR spectrum with a pair of coupled carbon-13 nuclear spins in the direction of NV color center-based nanoscale NMR on the optical detection magnetic resonance (ODMR) experimental platform [published in Adv. Quantum Technol. 2020, 3, 1900136 (2020)]. Due to the extremely weak microscopic NMR signals, it often takes a long time (hours to days) to accumulate signals in experiments for nanoscale 2D NMR spectroscopy measurements in order to obtain a high signal-to-noise ratio. To improve the detection efficiency, the research team led by Prof. Dr. Jiangfeng Du applied artificial intelligence methods to the data processing and analysis of 2D NMR spectra by training deep learning neural networks with model data and combining them with matrix filling methods, which finally made it possible to obtain nearly 4-fold (~5.7 dB) signal-to-noise ratio improvement even with a time consumption of 10%. Two-dimensional spectroscopy is the key to spin distance resolution and the basis of single-molecule structure resolution. This work provides a universal method applicable to the acceleration of two-dimensional NMR spectroscopy, which can be applied to the structure resolution of single molecules at the nanoscale. Fig. (a) After adopting the deep learning algorithm, it is possible to extract complex nanomagnetic spectral line information from a ...
View MoreRecently, the experimental course "Fundamentals of Quantum Information Technology", which is based on CIQTEK Diamond Quantum Computer for Education, was officially opened in the College of Physical Science and Technology of Central China Normal University in Wu Han, China. Students Using CIQTEK Diamond Quantum Computer for Education in the Fundamentals of Quantum Information Technology Course At this stage, the rapid development of quantum technology is not compatible with the serious lack of quantum technology practitioners, engineering, and technical personnel who do not have a deep enough understanding of quantum technology, they lack practical skills.

View MoreIn December, CIQTEK received a special gift, a thanks banner from the Magnetic Resonance Laboratory of Tsinghua University Analysis Center. A thanks banner is a traditional way to show thanks and gratitude in China. In November 2019, an electron paramagnetic resonance (EPR or ESR) spectroscopy in the Magnetic Resonance Laboratory of Tsinghua University's Analysis Center failed to measure the signal. After the discussions, the team decided to ask CIQTEK team for help. As the company with advanced EPR (ESR) spectroscopy technology, CIQTEK has the strength of independent research and development of EPR (ESR) instruments and professional service & support team. After arranging for engineers to visit the site, the EPR spectroscopy in the MR lab was able to detect the signal again after troubleshooting and maintenance. According to the feedback from the magnetic resonance laboratory of Tsinghua University Analysis Center, the same test conditions of manganese standard signal was the same as before the repair after the end of the repair and turn-on test (Figure 1); restart the instrument, the test was normal (Figure 2); adjust the field amplitude increased to five times, the signal intensity expanded to about five times (Figure 2); the manganese standard signal could be measured at different modulation frequencies. A fullerenes sample, the test is normal. It is reported that the EPR (ESR) spectroscopy was unable to measure the signal due to the damage of the modulation field system. For such problems, the CIQTEK EPR (ESR) engineers took only 4 working days from on-site inspection to restoration of the test, which greatly relieved the testing pressure in the laboratory and met the testing needs of the students and teachers. Since its inception, CIQTEK has been committed to helping our customers more efficiently promote the development of technology and explore the future of mankind. We take "first-class products, first-class service" as our aim, and always insist on customer first. Establishing excellent brand service is our constant pursuit. The Magnetic Resonance Laboratory of Tsinghua University Analytical Center wrote in the banner, "The maintenance work of EPR spectroscopy is professional, timely and reliable, setting standards for instrument industry." CIQTEK is honored to receive such high praise, and will continue to work hard and contribute to the revitalization of the high-end scientific instrument industry. Tsinghua University Analysis Center The Department of Analytical Chemistry at Tsinghua University was established in 1926 as one of the key "specialties" at the beginning of the Department of Chemistry.
