"Quantum computers elicit dreams of great computational feats to come. But they also promise a nightmare: They could break today’s security codes, rendering them no more secure than a TSA-approved luggage lock," according to Science News writer Julie Rehmeyer in her July 25, 2011 "Math Trek" column.
Now, for the first time, researchers including SFI Professor Cris Moore, have shown a security method to be immune to the type of attack that could bring down RSA, the cryptosystem in almost universal current use, she writes.
