QDAC-II Compact is a high-precision, 25-bit resolution, ultra-low-noise DAC with 24 voltage channel generators with a 1 MS/s sample rate and a step size of <0.2 μV. Each of the 24 channels has five voltage generators working in parallel: DC, sine, triangle, square, and arbitrary waveform.
Performs fast multi-dimensional gate voltage sweeps using a 300 kHz output filter. Once at your operation point, the QDAC is switchable to an ultra-low noise DC voltage with a 10 Hz output filter and 25-bit resolution, with minimal transients.
QDAC-II Compact is a versatile and easy-to-use solution. Controlled directly by SCPI commands with an endless number of applications, it can be stacked with multiple OPX1000 and QSwitch units to operate as one advanced quantum control system.
“QM’s chip packaging solutions are exquisite pieces of engineering that have enhanced our resonator Q-factors to as much as 200 million. It is clearly a very highly engineered product that I’m sure will be widely adopted in the field.”
"OPX played a crucial role in our advanced quantum experiments. This platform is the most flexible and user-friendly system in our lab. It saved us a significant amount of time, enabling us to concentrate on quantum science and make progress much faster compared to writing our own code. Furthermore, the Quantum Machines customer success team has been extremely helpful in addressing our needs and maximizing the solution's full potential."
