QDevil’s new product, called QDAC-II, is a 24 channel DAC (Digital to Analog Converters) that operates with ultra-low noise at a sample rate of 1 million samples per second, a thousand times faster than its predecessor. A key benefit of this device is that it enables much faster tuning of the qubits than previously possible. It can be used to provide DC and intermediate frequency control of quantum devices including gate electrodes, flux bias coils and other purposes. Each channel is also equipped with a DC current sensor with a resolution down to a few tens of picoamps with sampling rates up to 3 kHz. for uses such as gate leakage detection. Additional information about this product is available in a news release from QDevil here, a web page for the product here and a short video here.
