Application: Physical media incorporating colour centres for use in quantum systems (Patent ID: US20230409948A1)
The patent filed by Microsoft describes an apparatus involving a crystal with a color center that can interact with a magnetic field and an electromagnetic signal to induce changes in the electron spin resonance frequency of the color center. The apparatus includes multiple color centers within the crystal, each with its own unique electron spin resonance frequency dependent on the projection of the magnetic field onto the color center axis. By emitting specific electromagnetic signals matching these frequencies, energy level transitions can be induced in the color centers, potentially enabling qubit transformations or measurements.
Furthermore, the patent details a quantum system utilizing the crystal and color centers in conjunction with a magnetic field generator, an electromagnetic signal generator, a memory storing computer-readable instructions, and a processor. The processor is programmed to control the magnetic field and electromagnetic signal generators to manipulate the color centers based on quantum program instructions stored in memory. This system allows for precise addressing and control of the color centers within the crystal, potentially enabling quantum computing applications and quantum sensing capabilities.
