Researchers at ETH Zurich have succeeded, for the first time, in quickly and continuously correcting errors in digital quantum systems. This means they have overcome an important hurdle on the road to practical quantum computing.
The researchers achieved this important success using a chip, specially produced in ETH Zurich’s own cleanroom laboratory, which features a total of 17 superconducting qubits.
The highly specialised electronics used to control the qubits on the chip were manufactured by ETH spin-off Zurich Instruments. The chip itself is located on the lowest level of a large cryostat – a special cooling device – and operates at a temperature of just 0.01 Kelvin, barely above absolute zero.MORE
