SYSTEMS AND METHODS FOR SCALABLE CONTROL OF SPIN QUANTUM MEMORIES - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240013084 titled 'SYSTEMS AND METHODS FOR SCALABLE CONTROL OF SPIN QUANTUM MEMORIES

Simplified Explanation

The patent application describes a scalable point defect qubit control system that utilizes a diamond waveguide array and a microwave line. Here is a simplified explanation of the abstract:

• The system includes a diamond waveguide array with one or more diamond waveguides and a microwave line located nearby.
• Each diamond waveguide in the array contains one or more qubits encoded in point defect sites.
• The microwave line is designed to receive a direct current (dc) signal that can shift the energy level of each point defect qubit based on its position in the diamond waveguide array.
• The microwave line also receives an alternating current (ac) signal that can control the quantum state of a point defect qubit.
• The properties of the ac signal are determined by the shift in energy level induced by the dc signal.

Potential applications of this technology:

• Quantum computing: The scalable control system can be used to manipulate and control qubits encoded in diamond waveguides, which are essential for quantum computing.
• Quantum communication: The system can enable the transmission and manipulation of quantum information encoded in point defect qubits, facilitating secure communication protocols.

Problems solved by this technology:

• Scalability: The diamond waveguide array allows for the integration of multiple qubits, enabling the creation of larger and more powerful quantum systems.
• Control and manipulation: The system provides a means to shift the energy levels and control the quantum states of the qubits, which is crucial for performing quantum operations.

Benefits of this technology:

• Scalability: The ability to scale up the number of qubits is essential for building practical quantum computers with increased computational power.
• Precise control: The system allows for precise control and manipulation of qubits, enhancing the accuracy and reliability of quantum operations.
• Compatibility: The use of diamond waveguides and microwave technology makes the system compatible with existing quantum computing architectures, facilitating integration into current frameworks.
