The NovaDePro project addresses a core challenge in quantum information science: how to reliably detect and correct errors in quantum computing systems based on superconducting qubits. While recent years have seen rapid progress in building multi-qubit quantum processors, achieving truly fault-tolerant operation remains a formidable obstacle. At the heart of this problem lies the need for improved quantum error correction (QEC), which requires not only robust qubit performance, but also new hardware-efficient strategies for detecting and correcting errors in real time. Existing methods often rely on architectures and protocols that are difficult to scale or suffer from limitations in readout fidelity, calibration stability, or protection against environmental decoherence.
NovADePro was conceived to respond to these challenges from two complementary angles. First, it explores new physical mechanisms for detecting multi-qubit parity — a central operation in many QEC codes — using simplified yet tunable coupling architectures. Second, it aims to develop a new class of quantum circuits that incorporate intrinsic error protection into the physical design of the qubit itself. These two directions, while distinct, both serve the overarching goal of building more robust and scalable quantum processors capable of supporting the stringent demands of QEC.
The project is grounded in a recognition that overcoming the limitations of current approaches requires a departure from incremental tuning of existing designs. Instead, NovADePro pursues alternative circuit topologies, novel control paradigms, and material-platform integration strategies that may offer advantages in error suppression and ‘error diagnostis’.
The expected impact of the project lies in its potential to shift the capabilities of superconducting qubit platforms closer to fault-tolerant thresholds. By demonstrating novel error detection protocols and protected qubit architectures, NovADePro contributes to enabling future reliable quantum computation. The outcomes of NovADePro are anticipated to inform future approaches to building superconducting qubits specifically for realizing quantum error corrected quantum computers.
