Quantum computing laboratory kits, referring to this kind of Lab Kits, are transforming from symbols of cutting-edge scientific research into accessible tools for teaching and experimentation. Through its miniaturized and integrated design, it enables university teachers, students and researchers to practice on real physical systems, bridge the gap between theory and application, and serve as a key carrier for cultivating the next generation of quantum talents.
How to start teaching from scratch using quantum computing experimental platform
For those students with no foundation, the ideal experimental platform should be able to lead them to achieve a complete process from understanding to control. Take the "Gemini Lab" of Liangxuan Technology as an example. It is built as a full-stack experimental platform. Its teaching logic is to start from the observation of physical phenomena and then proceed step by step to quantum control. Students can personally debug pulse waveforms, complete a series of steps such as qubit initialization and logic gate operations, and use intuitive data charts to understand abstract quantum superposition states. Such a "ready-to-learn-out-of-the-box" design directly adapts to the existing physics experiment courses in colleges and universities, significantly lowering the teaching threshold.
The advantages of this platform are reflected in its openness and intuitiveness. It uses an open chassis design, so students can directly see the key modules such as internal magnets and radio frequency controls, breaking the barrier of the quantum system as a "black box". With the help of graphical programming and toolkits, students can start from the quantum circuit design and finally verify the algorithm on the real nuclear magnetic resonance quantum system. This kind of through experience from the underlying principles to the top-level applications cannot be replaced by pure software simulators.
What application scenarios are portable quantum computers suitable for?
As a portable quantum computer that creates a new application model, it has the characteristics of miniaturization and low cost. For example, a device like the "Quantum Spin Gemini Mini" weighs only 14 kilograms and is as big as a small printer. It is equipped with a complete operating system and touch screen. It can be easily moved and can be used as a "mobile quantum classroom." It is particularly suitable for conducting live demonstrations of quantum computing principles in lectures, seminars or between different classrooms, thereby making popular science and introductory education more flexible.
Portable devices play an important role in scientific research. They support the real operation of all basic quantum logic gates and have a complete curriculum from introductory to practical use. Researchers can use them for small-scale prototype verification of algorithms. They also play an important role in advanced teaching. Students can use it to conduct independent experimental exercises after class. Although its number of qubits is limited, it is enough for students to gain key practical experience in manipulating real qubits and characterizing decoherence characteristics. This is the basis for understanding the current computing technology in the NISQ (Noisy Intermediate Quantum) era.
What are the differences between quantum computing suites with different technical routes?
Mainstream laboratory kits are currently mainly based on nuclear magnetic resonance and superconductivity. These two technical paths have clear and clear applicable scenarios. Nuclear magnetic resonance paths, such as "Gemini Lab" and "Triangulum II" are representatives. Its biggest advantage is its stability and ease of use. It can operate at room temperature, has a relatively long coherence time, and the structure of the device is relatively open, making it particularly suitable for teaching demonstrations and basic principle experiments. Users can intuitively understand the physical process of treating the spin of an atomic nucleus as a qubit.
Focusing on cutting-edge scientific research and performance expansion is the superconducting quantum computing route. This type of system requires an extremely low temperature environment to operate, which is about 10 millikelvin, and is usually equipped with complex low-temperature equipment such as dilution refrigerators. Its advantages are fast qubit manipulation and large scalability potential. Laboratory-level superconducting quantum computing measurement and control systems such as Guoyi Quantum's SQMC series adopt modular designs and can be expanded from 4 bits to higher scales, providing a platform for research on topics such as quantum error correction and complex algorithms. However, their deployment and maintenance costs are also relatively high.
How to choose the right number of qubits for your lab
Clarifying the core needs of the laboratory is the key point in choosing the scale of qubits. For undergraduate teaching and general education on quantum computing, a 1-2-bit system is already sufficient. Such a scale can clearly demonstrate various core concepts such as qubits, quantum gates, superposition, and entanglement, and can run and equal baseline algorithms. For example, the "Gemini Lab" platform can achieve these algorithm experiments with extremely high fidelity and is cost-effective.
For graduate student training and scientific research purposes, a higher bit number and a more open system are needed. 3-bit and above systems, like the 3-bit "Triangular II", can support three-bit quantum gate operations and can be used to study more complex quantum optimization and dynamic simulation problems. However, for real research-level applications, such as quantum algorithm development, error mitigation research, etc., you have to consider superconducting quantum systems of 5 bits or higher. This type of system allows researchers to directly control the underlying hardware and conduct calibration, benchmark testing and decoherence studies, thereby accumulating key experience for future large-scale quantum computing.

What is the core function of quantum computing measurement and control system?
There is a "nerve center" connected between the user and the quantum chip, which is the quantum computing measurement and control system. It is as important as the quantum chip itself and cannot be underestimated. It needs to generate precise microwave signals that manipulate qubits, transmit them, and read extremely weak quantum state messages. Take Guodun Quantum's ez-Q® 2.0 system as an example. It can achieve synchronous control for quantum computers with a scale of thousands of bits. Its high precision and reliability have been proven in my country's "Zuchongzhihao" series of quantum computers.
For the laboratory environment, the modularity, scalability and ease of use of the measurement and control system are crucial. The SQMC superconducting quantum computing measurement and control system manufactured by Guoyi Quantum adopts a modular design with 4 bits as a unit, which can be gradually expanded according to the progress of research. The system provides a graphical interface and SDK to facilitate researchers to carry out experiments such as bit calibration and parameter scanning. This design allows laboratories to invest at a reasonable initial cost while retaining the flexibility for future upgrades to keep up with rapidly evolving technology trends.
How the quantum cloud platform expands the capabilities of the laboratory
Public cloud platforms such as Liangxuan Cloud are connected to real quantum machines and high-performance simulators with multiple technical routes and different bit sizes. The quantum cloud platform and privatized deployment services can greatly expand the resources and capabilities of a single laboratory. The laboratory does not need to purchase and maintain all the hardware on its own. Students can compare the execution effects of algorithms on different hardware through remote access, thereby gaining a broader experience.
If colleges and universities have higher data security requirements, customization requirements, or frequent use requirements, then a privatized quantum cloud platform is a better choice in this case. It can be deployed inside the campus to integrate existing quantum computing equipment in the laboratory, such as desktop nuclear magnetic quantum computers, as well as classical computing clusters to form a dedicated quantum computing environment. Students can submit tasks using the internal network, either for graphical programming or code development. The platform will provide a full set of functions such as task management and visual result analysis. This model not only ensures data security, but also achieves efficient sharing and unified management of resources. It is an ideal solution for building a school-level quantum computing teaching center.
The booming quantum computing laboratory suite, with its diverse options, marks that quantum technology education is entering a new stage that is more pragmatic and more popular. Whether it is a teaching platform for enlightenment or a scientific research system for cutting-edge exploration. These tools are transforming abstract quantum theory into tangible and verifiable experiments.
For those institutions that are planning to build or upgrade quantum computing laboratories, will they focus more on the broad coverage capabilities of basic teaching, or will they focus more on the breakthrough potential of cutting-edge science? How do you weigh and make choices between budget and goals? Feel free to express your opinion.
