Operation of a Quantum Computing Element

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method and architecture for operating a quantum computing element built on a network of 'shuttling lanes'—specialized pathways that allow for the controlled movement (shuttling) of spin qubits (quantum bits) through multiple junctions and manipulation zones. The approach enables qubits to be initialized, manipulated, and read out while freely moving across the network, passing through various processing locations, which is not possible in many existing architectures. This innovation allows the number of qubits to exceed the number of network junctions, supporting more flexible and scalable quantum computation.

Use CasesContent extracted from patent full text and abstract with AI.

• Universal quantum computers capable of running complex quantum algorithms across many qubits.
• Implementations of error-corrected quantum computing using surface codes or other quantum error correction techniques.
• Flexible quantum processors for research and industrial applications.
• Quantum simulators for modeling physical, chemical, or biological processes.
• Cryptography and cybersecurity solutions requiring high-performance quantum operations.

BenefitsContent extracted from patent full text and abstract with AI.

• Increases flexibility in qubit management, avoiding strict assignment between qubits and network cells, allowing qubits to move and interact anywhere in the network.
• Enables higher qubit density, as more qubits can be used than there are physical junctions, supporting scalable, large-scale quantum computing.
• Facilitates complex multi-qubit operations such as entanglement anywhere on the network, aiding in universal quantum computing.
• Reduces required number of loading/readout terminals, which can improve performance and reduce manufacturing complexity and thermal noise.
• Supports parallel operations and efficient implementation of error correction codes, boosting reliability and computational speed.
