"record long coherence times, 10 μs, for qubits, which defines number of quantum operations... carbon atoms have hollow tubular shape and 1 nm thickness... easily integrated into quantum devices and permits many possible ways to read out the quantum information. Also, the carbon tubes are very flexible and their vibrations can be used to store information from the qubit"
