Diamond quantum computing Educational Instrument
Diamond quantum computing educational instrument is based on the principle of NV center in diamond and spin magnetic resonance, which controls the physical quantities such as laser, microwave and magnetic field to conduct quantum control and readout of the spin state of NV center, to realize the function of quantum computing. The instrument works at ambient conditions without the need for cryogenic environments, which makes the operating cost of the instrument almost zero. It can demonstrate the basic concepts of quantum computing, includes qubits, quantum logic gates, and quantum algorithms. We not only provide the instrument but also a turnkey solution for the course.  The tabletop design enables it to easily adapt to a variety of teaching environments, such as quantum physics experiments, general quantum computing courses, and so on.

Experiment content
Diamond quantum computing educational instrument is composed of a 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 more teaching contents such as quantum precise measurement and optically detected magnetic resonance.

Instrument Set Up

Set up and adjust the instrument, get familiar with the principle of optically detected magnetic resonance, NV center, microwave generation and pulse contorl.


Continuous Wave Spectrum

Understand NV center qubit by measuring the optically detected magnetic resonance spectrum and get the resonance frequency for spin control.


Rabi Oscillation

The Rabi oscillation of NV center is measured, and get the microwave pulse length corresponding to the quantum logic gate.


Spin Echo

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 Measurement

T2 experiment shows the evolution of quantum superposition state and measures the decoherence time of NV center spin.


Dynamical Decoupling

The decoherence time is extended by designing the dynamical  decoupling sequence to average out the coupling between the qubit and the environment.


D.J. Algorithm

A two-qubit Deutsch-Jozsa quantum algorithm is realized on the NV center quantum processor.
