Applications in Spectral Analysis and Structural Analysis


CIQTEK Optically Detected Magnetic Resonance Spectrometer (ODMR) can be applied to the analysis of the structure and function of biological macromolecules, single-molecule imaging, subcellular imaging, cell sorting, etc., and the measurement scale spans the order of nanometers to micrometers.


- Electron Paramagnetic Resonance (EPR) for Single Protein and Single Molecule

EPR (ESR) spectroscopy of individual protein molecules at ambient conditions was studied by analyzing the interaction between the NV center and external electron spins. The measurement of materials at the nanoscale or even at a single spin level can obtain information hidden by a statistical average of the ensemble, to understand the structure and properties of materials more fundamentally.


- Nanoscale Nuclear Magnetic Resonance

In the field of single molecular NMR, rapid progress has been made in recent years. In 2016, NMR spectra of individual proteins were obtained using this technique. With the development of technology, the resolution of the chemical shift has been dramatically improved. The resolution of 1 Hz (sample volume: picoliter) can be achieved, and NMR at a single-cell scale can be realized.


- Detection of Temperature, Magnetic Field, Action Potential in Living Cells

The application of NV center in diamond nanoparticles to track living cells in real-time can achieve nanoscale local temperature measurement, to monitor local temperature changes in active states such as cancer cells and feedback on their physiological conditions. The application of NV color centers to detect the action potentials of single neurons in worms has laid a foundation for the application of this technology in the field of neuroscience. The magnetic field imaging of magnetotactic bacteria is realized by applying the magnetic properties of NV centers.



Applications in Quantum Computing


Quantum Computing

Quantum computing refers to the use of quantum mechanical phenomena to study computing systems to perform data operations.


Diamond NV Centers as Qubits

The NV center spin in a diamond can be initialized, manipulated, and read out with high efficiency at ambient conditions, and has a long coherence time, which is an ideal qubit.


Quantum Computing Application Examples

> High Fidelity Quantum Control

The microwave pulse can be used to control the flip of the spin state of the NV center to form a quantum gate. The operation fidelity of the single-qubit quantum gate can reach 99.99 % through a sophisticated design of the pulse sequence. This is the current record of single-qubit quantum gate fidelity and reaches a fault tolerance threshold.

> Quantum Algorithm

Quantum algorithm uses many fundamental properties of quantum mechanics, such as quantum superposition, parallelism, entanglement, measurement collapse, etc. These physical properties bring great help to the improvement of computational efficiency and form a brand-new computational mode - quantum algorithm. D - J algorithm and large number factorization algorithm were demonstrated using NV center, which is an essential step towards realizing room temperature quantum computer

> Quantum Error Correction

Errors are always inevitable, both in classical and quantum computing. In classical information processing, coding is often used to reduce the probability of error. Similarly, in quantum computation, the probability of error occurrence can also be reduced through quantum error correction. Electron spins in diamonds can be operated quickly, while nuclear spins have longer coherence time. The hybrid system consisting of electronic spin and nearby nuclear spin is used to demonstrate the quantum error correction process, which is a crucial step towards the scalability of quantum computation.
