Vivace is our new 4GHz platform for high frequency signal generation and analysis, aimed at emerging applications in quantum technology. It has 8 RF input ports, 8 RF output ports, 4 digital input and 4 digital output ports, all synchronized to one very stable clock. Two branches of firmware provide a highly configurable platform for complex experiments with rigid timing constraints on multiple phase-coherent signals. Continuous wave mode is a microwave big-brother to our multifrequency lockin amplifier. Pulse sequencing mode is our new approach to timed pulse generation and analysis for control and readout of quantum systems.
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 (viˈvɑ tʃɛ), Italian for fast and lively, is used to denote tempo 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 ). Vivace uses tuning algorithms to lock-in on multiple, intermodulating tones, similar to musicians in an orchestra who create harmony by playing in the same key. The conductor sets the tempo, cuing each musician when to play and how to shape each tone. You compose your experiment in Python and Vivce will conduct it 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 that can be amplitude-scaled, time-stretched, looped, or multiplied with a carrier tone, with each operation controlled at run-time. Input signals are sampled and matched with a pre-stored templates, allowing for conditional triggering of new events with as little as than 200 ns latency.
Operate Vivace 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/demodulation of signals up to 4GHz, with no analog mixers and zero NCO leakage.
