Quantum bits in carbon nanotubes

One step toward telecom-compatible quantum communication: new experimental results from the BME Spin Spectroscopy research group published in ACS Nano.
 

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.
