Life of quantum cryptography can prevent death,our deaths.
This does not appear in fiction.This happens right here in
Spore.
1.
A quantum computer is any device for computation that
makes direct use of distinctively quantum mechanical
phenomena, such as superposition and entanglement, to
perform operations on data. In a classical (or conventional)
computer, the amount of data is measured by bits; in a quantum
computer, it is measured by qubits.
2.For problems with all four properties, it will take an average of
(n + 1)/2 guesses to find the answer using a classical computer.
The time for a quantum computer to solve this will be proportional
to the square root of n. That can be a very large speedup, reducing
some problems from years to seconds. It can be
used to attack symmetric ciphers such as Triple DES and AES by
attempting to guess the secret key. But it is also easy to defend
against, by doubling the size of this key. There are also more
complicated methods for secure communication, such as using
quantum cryptography.
