Abstract
(EN)

This disclosure relates to quantum electronic devices for storing qubits. In particular, this disclosure relates to a quantum electronic device comprising a carbon nanosphere adapted to store a qubit represented by an electron spin and a control and readout device to set the qubit and read the qubit stored on the carbon nanosphere. Qubits stored on carbon nanospheres have a long electron spin lifetime at room temperature. This disclosure further relates to a method for quantum computing. The method comprises storing a qubit represented by an electron spin on a carbon nanosphere, performing a quantum operation on the qubit to generate a resulting qubit and reading the resulting qubit from the nanosphere. There is further provided a spintronic device comprising multiple carbon nanospheres adapted to provide a qubit represented by an electron spin in that carbon nanosphere and a control device to facilitate interaction between the qubits to perform a quantum operation.
