Quantum Random-Number Generators
Existing encryption algorithms can be strengthened by adding in truly random
numbers. Also known as quantum keys, these are the strongest encryption keys
currently available, and they make use of cosmic background energy to harness
perfectly occurring randomness. Scientists measure the crackle of energy in the fabric
of the universe as it spontaneously creates and self-destructs. It is impossible to
predict the frequency and timing of the cosmically sourced radioactive particles as
they strike the electronic sensors, allowing quantum physicists to harness this
quantum noise and convert it into true random numbers.
Banks, governments, and private cloud carriers are already implementing quantum
random-number technology. There is a range of additional uses for the technology,
including blockchain software and other forms of encrypted data, that would benefit
from protection against both a classical computer and a quantum computer.

A quantum random-number generator (QRNG) by itself will not be able to thwart a
quantum computer forever, but as Dr. Raymond Newell of Los Alamos National Lab
notes, “A quantum number generator isn’t just used for quantum cryptography; it can
