Cryptography: A dedicated research program should be implemented to develop a mature quantum cryptography technology. Theoretical and experimental
work is in progress among a small number of select groups (QISP, In-Q-Tel, universities, etc.), but this field is not advancing fast enough for
practical applications to become available to meet increasing
adversarial threats against secured military and intelligence communications. The goal of proposed quantum cryptography research is to bring the
theoretical and experimental foundation of quantum cryptography and secure quantum information processing to maturity, and to fully develop and
implement quantum entanglement/teleportation-based cryptography technology.
Recent experimental work has demonstrated that a completely secure quantum key can be generated and distributed for the communication and decoding of
encrypted messages using entangled photons. Any eavesdropper’s attempt to intercept the quantum key will alter the
contents in a detectable way, enabling users to discard the compromised parts of the data.
There is much more work that needs to be done in this area. I recommend that the AFRL implement a $1 million/year program for five years in order to
advance the state-of-art in quantum cryptography technology.
Parallel Universes/Parallel Spaces (Everett, 1957; Wheeler, 1957, 1962; DeWitt, 1970; DeWitt
and Graham, 1973; Jammer, 1974; Davies, 1980; Wolf, 1988; Kaku, 1994; Visser, 1995 and
Section 2.1): There are only two other research tracts that are concerned with parallel universes besides 3-brane theory. The first tract is the
traversable wormhole research that was discussed in Section 2.1. Traversable wormholes can connect many different universes in the “multiverse”
(i.e., a conglomeration of many universes), and these are called inter-universe wormholes.
However, traversable wormhole physics (a.k.a. Einstein’s General Relativity Theory) does not provide a physical prescription for the existence and
nature (i.e., fundamental parameters and
physical laws) of other putative universes. The difference between inter-universe and intrauniverse (i.e., two distant regions of one universe are
connected with each other) wormholes arises only at the level of global geometry and global topology. Local physics near the throat of a
traversable wormhole is insensitive to issues of intra-universal or inter-universal travel. An observer in the vicinity of the throat, while making
local measurements, would not be able to tell
whether he was traveling to another universe or to a remote part of our own universe. And one cannot rely on the topological (as opposed to
geometrical) information to determine which is the
case, because topological information is not enough to uniquely characterize an inter-universe
connection. And General Relativity Theory does not fix the topology of spacetime, so we cannot ascertain the existence of other universes. [Note:
Traversable wormholes are also geometrically
possible for higher dimensional spaces.]
