MITIGATING STRAY-COUPLING VIA MULTI-JUNCTION QUBITS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240039532 titled 'MITIGATING STRAY-COUPLING VIA MULTI-JUNCTION QUBITS

Simplified Explanation

The patent application describes systems and techniques for reducing stray-coupling in multi-junction qubits. Here is a simplified explanation of the abstract:

• A device is provided that includes a first qubit with multiple josephson junctions between capacitor pads.
• The device also includes multiple second qubits, each coupled to different capacitor pads.
• The second qubits are not coupled to the same capacitor pad.

Potential applications of this technology:

• Quantum computing: The technology can be used in quantum computers to improve the performance and reliability of multi-junction qubits.
• Quantum communication: The technology can enhance the efficiency and accuracy of quantum communication systems.

Problems solved by this technology:

• Stray-coupling: The technology mitigates stray-coupling, which is a common issue in multi-junction qubits. Stray-coupling can lead to errors and instability in quantum systems.

Benefits of this technology:

• Improved qubit performance: By reducing stray-coupling, the technology improves the performance and reliability of multi-junction qubits.
• Enhanced quantum system stability: The technology increases the stability of quantum systems by minimizing the impact of stray-coupling.
• Higher accuracy in quantum operations: With reduced stray-coupling, the technology enables more accurate quantum operations, leading to better results in quantum computing and communication.
