Abstract: According to one implementation, a quantum computing device, includes a plurality of quantum bits, and waveform generators. Each waveform generator is coupled to a respective one of the quantum bits. Each of the waveform generators further include: a current-pulse generator, an adjustable negative resistor, an adjustable capacitor, and a transformer. Moreover, each waveform generator is configured to program the respective quantum bit that is coupled thereto, using less than a few milliwatts of power. Other implementations of systems, methods, and computer program products are also disclosed.
