Once again accurate measurement is the key to understanding value.
Finnish researchers claim quantum computing breakthrough in Techxplore
Scientists have created a device which could make it easier to harness super-fast quantum computers for real-world applications, a team at Finland's Aalto University said on Wednesday.
Quantum computers are a new generation of machines powered by energy transfers between so-called "artificial atoms"—electrical circuits a fraction of a millimetre across. Scientists believe the devices will eventually be able to vastly outperform even the world's most powerful conventional supercomputers.
Last October, Google announced it had reached "quantum supremacy" by creating a machine which executed a calculation in 200 seconds that would have taken a classic computer 10,000 years to complete. Although a remarkable leap in the field, Google's Sycamore computer was held back by errors in its processing, caused in part by shortcomings in how the device measured the energy being stored in its memory. ...
