0000 Techniques are described for controlling qubits using baseband pulse sequences. Many, or even all, qubits in a system can be controlled by baseband pulse sequences that are synchronized to a clock signal shared by the qubits. The baseband pulse control techniques allow many qubits to be driven with the same parameterized baseband pulse sequence applied based on a common clock signal, with parameters of the baseband pulse sequence selected based on the desired operation. This approach greatly simplifies the electronics needed to drive a collection of qubits, as there is no need for picosecond timing, nor the complexities that arise from varied gate durations.
