Quantum bits (qubits) emitting and absorbing photons in the telecom wavelength window (1300-1600 nm) are a key requirement for quantum communication based on fibre optics. However, the best-known, most popular solid-state qubits, such as the nitrogen-vacancy center in diamond, are active in the optical wavelength window (380-740 nm). Therefore, the recent experimental results of the BME Spin Spectroscopy research group, characterising the interaction of electrons in carbon nanotubes and telecom-wavelength photons, might be of high importance to establish novel telecom-compatible qubits. The authors believe that their findings may foster the application of carbon nanotubes in quantum technology.
News portal of the Hungarian Academy of Sciences covers research results of our colleague Péter Makk, as one of the most successful recent recipients of the Bolyai Scholarship.
