Our digital microwave platforms offer synchronous signal synthesis and analysis on multiple ports, in a single device. Features include:
Vivace is fast and flexible. It can implement any qubit-cavity measurement we thought of and the guys at IMP are constantly improving it. They are always open for suggestions and quick to answer any questions we might have. I give them 10/10!

Vivace 'fast and lively' and Presto 'very, very fast' are named after tempos in music, an art form with many analogies to nonlinear physics and quantum technology. Intermodulation was first observed in music by the Italian violinist Giuseppe Tartini (see Tartini Tone ). Digital tuning algorithms lock in on multiple, intermodulating tones, similar to musicians in an orchestra who create harmony by playing in the same key. The Event Organizer sets the tempo, cuing and shaping each tone. You compose your measurement in Python, Vivace and Presto will conduct your experiment with the precision needed for high fidelity measurement and control of the quantum state.

Control pulse-based measurements with sub nanosecond resolution using the Quantum Event Organizer™. Each event cues the start of output pulses or input analysis. Output pulses are constructed from pre-stored templates which can be amplitude scaled, time stretched, looped, or multiplied with a carrier tone. Input analysis includes: sample, sample and average, demodulation and template matching. The latter allows for conditional triggering of new output events with as little as 200 ns total latency.
Operate Vivace and Presto as a multifrequency lock-in amplifier. Digital mixers up and down covert the measurement band with a Numerically Controlled Oscillator (NCO), giving perfect IQ modulation and demodulation with no analog mixers and zero NCO leakage.
