Problem
Scaling quantum processors to a large number of qubits faces challenges in maintaining signal fidelity due to noise and heat generation from extensive cabling and control electronics. Traditional control methods require numerous coaxial cables, which introduce significant heat load into the cryogenic environment and limit the density of control channels.
Solution
Viqthor provides microwave error correction and photonic signal processing technologies designed to enhance qubit readout fidelity and streamline the control of large-scale quantum processors. Their solutions utilize RF-over-fiber technology to replace bulky coaxial cables with optical fibers, significantly reducing heat load and cabling complexity. By employing multiplexing techniques and real-time embedded calibration, Viqthor's technology enables efficient and high-fidelity control of up to one million qubits, optimizing quantum processing unit (QPU) availability and performance.
