In the original version of this Article, we claimed electrical control of a quantum-dot charge qubit on a timescale orders of magnitude faster than previous measurements on electrically controlled charge- or spin-based qubits. After publication, we became aware of a related work by Dovzhenko et al. on charge qubits that showed electrical control on a comparable timescale. Therefore, the Abstract of this Article has now been corrected to ‘Here we demonstrate complete control of the quantum-dot charge qubit on the picosecond scale’. Furthermore, the following statement has been added to the Discussion section to recognize the work of Dovzhenko et al.: ‘A similar timescale for electrical control was also observed in ref. 27 in a quantum-dot charge qubit using non-adiabatic voltage pulses.’
