Problem
Current quantum computing systems face challenges in maintaining qubit stability and accuracy, leading to errors that hinder reliable algorithm execution and limit the potential for practical applications. Conventional approaches to quantum error correction often require a large number of physical qubits, adding complexity and cost.
Solution
Quantum Circuits is developing a full-stack quantum computing system based on superconducting Dual-Rail Cavity Qubits (DRQ) with built-in error detection. This technology enhances system performance by actively detecting and processing quantum errors, specifically single photon loss, the dominant error channel in superconducting cavities. The DRQ architecture enables Quantum Error Detection (QED), allowing for the identification and removal of erasure events, leading to higher fidelities and more reliable computation. The system also features Real-Time Control Flow (RTCF) for advanced classical operations in parallel with quantum systems, and Error Detection Handling (EDH) which allows users to manage QED themselves.
Target Audience
The primary target audience includes researchers, developers, and enterprises seeking to explore and implement quantum computing solutions for complex problems, particularly those requiring high fidelity and error awareness.
