  One of the possible representations of three-valued instantaneous noise-based
logic is proposed. The third value is an uncertain bit value, which can be
useful in artificial intelligence applications. There is a forth value, too,
that can represent a non-existing bit (vacuum-state) that is the same (1
numeric value) for all bits, however that is a squeezed state common for all
bits. Some logic gates are explored. A ternary Universe has a significant
advantage compared to the standard binary one: its amplitude is never zero
during any clock period. All the known binary logic gates work for the binary
bit values in the same way as earlier therefore the former binary algorithms
can be run in the ternary system with no change and without the problems posed
by zero values of the Universe.
