SemiQon builds scalable quantum processing units for quantum computing using semiconductor quantum-dot qubits and cryogenic ultra-low dissipation CMOS hardware.
It expands upon VTT’s groundbreaking demonstration of monolithically integrated on-chip quasi-dissipationless cryogenic multiplexers based on proprietary CMOS technology and devices with extremely low noise levels.
The ultra-low-charge-noise background of quantum-dot devices at relatively higher temperatures, above 1 K, was demonstrated and served as the foundation for the company’s goals. This was done using the same process to fabricate qubits and CMOS circuits on the same chip.
