Quantum computing a step closer with ‘world’s smallest’ memory
1 min read
Scientists at The University of Utah have successfully transferred spin information from an electron to a more robust atomic nucleus, creating what could be the world's smallest computer memory.
The team was able to store data for 112 seconds, thousands of times longer than memories storing information on electron spin. It is believed to be the first demonstration of electrically readable nuclear spin memory and could pave the way for spintronics and quantum computing of the future.
"The length of spin memory we observed is more than adequate to create memories for computers," said Professor Christoph Boehme, pictured, associate professor of physics. "It's a completely new way of storing and reading information."
Boehme, who led the team, created a custom built 240GHz pulsed electron paramagnetic resonance spectrometer to control the spin of nuclei in a highly magnetised, low temperature environment. (8.59 Tesla, -269.5°C).
The scientists are now looking to carry out the procedure at higher temperatures and without the need for strong magnetic fields. Implementation of the new technology in future computers is said to be 'more than a decade, less than a century' away, according to associate quantum physicist Dane McCamey.
