C12 Quantum Electronics: Carbon’s Quantum Leap Toward Scalable Quantum Computing
C12 Quantum Electronics is at the forefront of advancing quantum computing technology by harnessing the unique properties of carbon nanotubes. Their breakthrough achievement in developing a suspended carbon nanotube quantum circuit with a record coherence time of approximately 1.3 microseconds—100 times greater than previous carbon-based qubits and tenfold longer than comparable silicon qubits—marks a significant milestone in the field. This achievement, demonstrated under practical operating conditions at 300 millikelvin, highlights carbon's exceptional thermal robustness and noise reduction capabilities, enabling denser and more scalable quantum chip architectures.
What sets C12’s approach apart is their innovative circuit quantum electrodynamics (cQED) architecture, where a single electron in a carbon nanotube couples with microwave photons inside a resonator. This elegant design eliminates common sources of decoherence found in other qubit platforms and opens the door to efficient long-range qubit coupling and multiplexed readout—a key for fault-tolerant quantum error correction. With these advances, carbon-based quantum hardware is poised to become a vital contender in the race for practical, large-scale quantum computing.
