The SHFSG+ Signal Generator, SHFQC+ Qubit Controller and SHFQA+ Quantum Analyzer are designed to the limits of analog performance. The SHF+ product line unites high-fidelity qubit control and quality performance and accelerates the development of longer coherence time qubits and scaling up quantum processing units (QPUs).
The SHFSG+, SHFQC+ and SHFQA+ improve the signal-to-noise ratio (SNR) by 10 dB, placing them among the highest available on the market. Such a high SNR dramatically reduces thermal qubit excitation and, in turn, maximizes quantum computing algorithm fidelity. A substantially improved phase noise allows for suppressing phase errors in the control of long-lived qubits.
“By working closely with many leading quantum computing research groups, we’ve observed that the setup allows for reduction of the phase error limit up to ten times and reaches levels of 10-6 for qubits in the millisecond lifetime range,” said Dr. Bruno Küng, principal product marketing manager at Zurich Instruments.
In addition to a noise-optimized signal chain, the SHF+ products also offer the ability to actively mute the output for measurements on even the most sensitive of qubits.
“Strong connections to research have allowed us to stay on the frontiers of science, as well as to scale our operations in a sustainable way. We thank our R&D teams for developing the SHF+ line, and to institutes such as ETH Zurich and many others for performing validations. This is a step towards more computational quantum power: better and longer quantum circuits, even for a few qubits, and the use of larger chips for more powerful QPUs. The story goes on — toward 4 9s and hundreds of qubits to accelerate the second quantum revolution,” concluded Dr. Sadik Hafizovic, the CEO of Zurich Instruments.
The SHFQC+, SHFSG+ and SHFQA+ will be launched at the meeting of the American Physical Society, March 3 through March 8 in Minneapolis, Minnesota. Zurich Instruments’ Quantum Technologies team is looking forward to meeting interested parties at Booth 811.
