Quantum memory device could stop unhackable networks from failing

A quantum version of a random access memory can read and write information 1000 times, and could eventually become a key component in long-distance quantum networks.

In conventional computers, random access memory (RAM) is essential for short-term information storage. Random access quantum memory (RAQM) is similar, and the expectation is that it will be vital for the smooth running of an unhackable quantum Internet connecting cities. This is because quantum information degrades easily as it travels – adding RAQMs at…
