Intel teamed up with QuTech to work on another approach to quantum control.     Image: Tim Herman / Intel Corporation Intel's quantum computing efforts are starting to show tangible results: two years after the company first unveiled its Horse Ridge cryogenic control chip, researchers have demonstrated that the technology is delivering on its original promise, and paving the way for quantum computers to become more practical. Practicality, in effect, is not quantum devices' most remarkable trait. In their current format, quantum computers rely on quantum chips that need to be cooled down to extreme temperatures, in order to exert better control over the fragile qubits on the processor. Typically, qubits operate at 20 millikelvin, or about...

Linde and Bluefors to develop cryogenic hardware for quantum computing

cold storage
This week, the Anglo-German-American industrial gas and chemicals maker Linde announced a new partnership with Finnish refrigeration technology maker Bluefors to develop and scale a product for quantum computing cryogenics. So could this rarefied segment of the refrigeration technologies sector become the next version of the still-red-hot investment market for cold-storage logistics? According to an announcement from the two companies this week, Linde will bring to bear its experience as the world leader in large cryogenic installations, combining with Bluefors’ ultra-low temperature interface, which is needed for quantum computing. Together, the companies say, their combined approach will ensure cryogenics are ready for the “next steps” in large-scale quantum computing, in terms of cooling power, efficiency and robustness.
