Supporting cutting-edge fields, the "quantum future" of diamond wafers

With the iteration of diamond technology, diamonds and their products are playing an increasingly important role in aerospace,machine tool machinery, and other fields, which also gives them broader imagination space in cutting-edge fields such as quantum technology, biomedicine, and semiconductors.

The application of diamond in the quantum field mainly benefits from its unique physical properties, such as the nitrogen vacancy (NV) centers inside, which maintain the stability of quantum states at room temperature and can interact with light, making diamond an ideal physical platform for developing high-performance quantum sensors and quantum computing components.

Quantum sensor

The NV center of diamond can be operated at room temperature through optical and radio frequency excitation, utilizing the splitting of the Zeeman effect to quantify the external magnetic field and achieve high sensitivity quantum magnetic field sensing (MDPI). Compared to other technologies such as optical pump magnetometers, superconducting quantum interference devices (SQUID), and microelectromechanical systems (MEMS), this type of sensor has the advantages of no cooling and high spatial resolution. The high performance of diamond NV center sensors and their ability to operate stably at room temperature provide possibilities for their applications in fields such as biological imaging and magnetic resonance imaging (MRI) technology improvement.

Quantum computing

In the field of quantum computing, diamond NV centers are considered a powerful candidate for implementing quantum bits due to their stable spin state at room temperature and ability to communicate with states through light (Nature). Compared with superconducting qubits that need to work in environments close to absolute zero, quantum bits in diamond NV centers can operate at room temperature, greatly simplifying the design and expansion of quantum computers.

Quantum storage

The diamond NV center also enables rapid manipulation of electron and nuclear spins on the nanosecond to microsecond time scales, which is crucial for logical operations. In addition, the diamond NV center can interact with nearby nuclear spins, utilizing these nuclear spins to provide additional quantum states for logical operations or long-term storage of quantum information, and can maintain a longer coherence time even at room temperature.

Although diamond NV centers have shown great potential in the field of quantum technology, they still face challenges in their further application and development, including improving the accuracy of NV center generation and control, extending integration to large-scale quantum systems, and cost-effectiveness.
