Intermodulation Products makes Presto, a combined microwave signal generator and analyzer especially suited
for quantum technologies such as characterization of superconducting qubits and control of multi-qubit chips.
Presto offers a high density of synchronized ports and removes the need of external IQ mixers or local
oscillators, simplifying the experimental setup and allowing for scalable control of many qubits. By making
use of the latest development in RF system-on-a-chip Presto integrates both high-speed ADCs and DACs not just
in a single box, but in a single chip, providing the lowest possible feedback latency for applications such as
qubit reset, as well as extremely low cross-port jitter. Single and multi-qubit gates, multi-level state
discrimination and randomized benchmarking can all be easily implemented using a Python API where complex wave
forms and filter matches are precisely scheduled in time. Other phenomena such as noise squeezing and noise
correlation can be studied using a multifrequency continuous wave mode.
Google's mission is to organize the world’s information and make it universally accessible and useful, and we
advance that mission every day in incredible new ways. Research across Google provides new ways of looking at
old problems and helps transform how we all work and live, and we think the biggest impact comes when everyone
in the world can access it. To that end, we use state-of-the-art computer science techniques to solve problems
for our users, our customers and the world, making it easier for you to do things every day, whether it’s
searching for photos of people you love, breaking down language barriers, or helping you get things done with
your own personal digital assistant.
Keysight's Quantum Engineering Solutions group enables your breakthroughs in quantum computing, sensing,
