Hacking Quantum Cryptography Just Got Harder With quantum
encryption, in which a message gets encoded in bits represented
by particles in different states, a secret message can remain
secure even if the system is compromised by a malicious hacker.

matter how complex they are, most secret codes turn out to be
breakable. Producing the ultimate secure code may require
encoding a secret message inside the quantum relationship
between atoms, scientists say. Artur Ekert, director of the
Center for Quantum Technologies at the National University of
Singapore, presented the new findings here at the annual meeting
of the American Association for the Advancement of Science.
Ekert, speaking Saturday (Feb. 18), described how decoders can
adjust for a compromised encryption device, as long as they know
the degree of compromise. The subject of subatomic particles is
a large step away from the use of papyrus, the ancient writing
material employed in the first k
