Archer Materials Advances Quantum Carbon Film Technology
Archer Materials Limited (ASX: AXE) has announced significant advancements in their quantum carbon film technology, marking a pivotal step towards the realization of quantum devices such as qubits and magnetic sensors.
Instant Summary:
- Improved electron spin lifetime to 800 ns at room temperature.
- Enhanced sample-to-sample repeatability and uniformity.
- Testing initiated on nanoscale islands for key quantum properties.
- Collaboration with Queen Mary University and EPFL for further development.
Technological Advancements
Archer Materials has made a breakthrough in enhancing the electron spin lifetime of its quantum carbon film, achieving a duration of 800 nanoseconds at room temperature. This marks a substantial improvement from the previous 385 nanoseconds, indicating progress towards the development of quantum devices like qubits and magnetic sensors.
The company has also improved the reproducibility and uniformity of these films, which are critical for the practical application of quantum technology. The advancements have been achieved through a collaborative effort with Queen Mary University of London and The École Polytechnique Fédérale de Lausanne, focusing on key quantum properties such as spin readout.
Testing and Verification
Archer has begun testing devices fabricated with nanoscale islands of the carbon films to verify essential quantum properties. These tests are crucial for demonstrating the functionality of quantum effects like the Coulomb blockade and electrically detected magnetic resonance (EDMR), which are vital for the realization of quantum computing and sensing devices.
The improvements in uniformity and variability, with standard deviations reduced to approximately 7%, are significant for scaling the technology from single qubits or sensor pixels to larger applications. The ability to maintain electron spin lifetime across different substrates is also a key focus of ongoing research.
Collaborative Efforts and Future Goals
Archer's collaboration with EPFL is currently directed towards developing EDMR on the company's carbon films, with initial tests on electrical readout devices underway. This approach sets Archer's technology apart from others that rely on optical systems for readout, such as diamond-based technologies.
The company is also working with Queen Mary University to extend Coulomb blockade measurements to single spin readout in carbon nano onions, aiming to apply these findings to carbon film-based qubits. These efforts are part of the 12CQ project, which seeks to bring quantum computing and sensing into everyday environments.
The advancements in Archer's quantum carbon films are likely to positively impact the company's stock, as they represent a significant step towards the commercialization of quantum technology. The improvements in spin lifetime and reproducibility enhance the potential for practical applications in quantum computing and sensing, potentially attracting investor interest and partnerships.
