Qubits driven with a Josephson arbitrary waveform synthesizer
Acronym
q.JAWS
Description of the granted funding
The q.JAWS project generates arbitrary quantized voltage waveforms at a cryogenic temperature. The goal is a nearly ideal signal generator for quantum technologies: being able to synthesize almost perfectly accurate and noise-free arbitrary signals in a wide band from 0 Hz to 10 GHz, at an affordable price and energy-efficiently. The method is based on ultrafast optoelectronics that drives Josephson junctions, which quantize the signal. As a proof-of-concept application we drive a superconducting quantum bit (qubit) with a voltage signal, and benchmark the corresponding single-qubit gate error. Our concept holds the promise of scalability to a large number of independent outputs in one cryogenic system, such as a multi-qubit quantum computer.
