Earlier this year, Archer announced that it had made advances in optimising and validating the 12CQ qubit material coherence times (ASX ann.
The Archer team prepared and characterised the coherence properties of over 150 separately synthesised qubit material batches. As a result of this work, the Archer team has engineered the quantum properties of its unique qubit material to achieve electron spin coherence times exceeding 230 nanoseconds at room temperature1 while maintaining the intrinsic metallic-like character of the qubit material. This was achieved by making the qubit material using a different precursor and applying post-synthesis treatments.
Archer believes that no other similar nanomaterial has been shown to achieve such long-lived electron spin coherence at room temperature2 . The long room temperature quantum coherence times had previously3 only been achieved for the qubit material at extremely low temperatures of approximately -173-degreeC. In the context of qubit processor development, the increase in quantum coherence time at room temperature is significant. By extending quantum coherence times, qubit materials can maintain stable quantum states for longer durations, providing a solid foundation for executing more sophisticated quantum algorithms and achieving reliable quantum computations
Archer increased its qubit material room temperature capabilities by over 30%, meaning it can now routinely prepare qubit material maintaining quantum superposition states for over 30% longer than previously achieved at room temperature3
