CIQTEK Diamond Quantum Computer for Education is a teaching instrument based on the diamond's spin magnetic resonance of the nitrogen-vacancy (NV) center. 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 settings for conducting quantum mechanics and quantum computing experimental courses.
Diamond Quantum Computer for Education consists of the microwave module, optical module, power module, control and acquisition module. The rich hardware enables the instrument to support a variety of basic experiments related to quantum computing, as well as the development of additional teaching contents such as the quantum precise measurement and optically detected magnetic resonance (ODMR).
Set up and adjust the instrument, get familiar with the principle of optically detected magnetic resonance, nitrogen-vacancy (NV) center in diamonds, microwave generation, and pulse control.
Measure optically detected magnetic resonance spectra of NV centers, determine microwave resonance frequencies, and understand quantum bits.
Measurement of Rabi oscillations in NV color centers driven by microwaves and determine the microwave pulse corresponding to a quantum logic gate.
Spin echo is an effective technique used to suppress the coupling between the qubit and the environment, so as to prolong the coherence time.
T2 experiment shows the evolution of the quantum superposition state and measures the decoherence time of NV center spin.
The decoherence time is extended by designing the dynamical decoupling sequence to average out the coupling between the qubit and the environment.
A Deutsch-Jozsa quantum algorithm is realized on the NV center quantum processor.
