Hair - Strands of human hair would be good media for
storing data. Data could be etched into the hair strand using
a laser.
Skin - Micro-tattooing technology, or perhaps by ‘dying’
the tissue with a memory-bearing dye, perhaps one that is
infused with micro-crystalline storage particles of some sort.
Quantum Storage
Possibly the most far-out concept so far involves quantum
mechanics and computing. Although the theory behind
quantum computing is complex, quantum storage basically
boils down to the storage medium being so small that not
even a microscope would be able to see it. According to
Mozy, by EMC, a single bit of information could be encoded
on a quantum mechanical system - the spin of an electron
for example. This could then be read and deciphered by a
quantum computer.
As with most new technologies, there are difficulties involved. Alex Knapp writes for Forbes that “unlike a regular
bit on the computer you’re reading, which can either exist
as either a 1 or a 0, a quantum bit (“qubit”) can exist in a
quantum superposition – meaning it exists simultaneously
in all of its possible states until it’s observed. As a result, information stored as qubits has a tendency to develop errors
and degrade in fract [ۜ
