A circuit for precise random frequency synthesis via a frequency locked loop
Frequency synthesis (FS) is a technique vital for all kinds of radio
frequency (RF) communications, such as: mobile phones, Bluetooth, Wi-Fi, radio,
TV and satellite, and in other equipment requiring periodic signals of stable
and programmable frequency. In this work, we present a generalization of the FS
technique to random, non-periodic signals, whose main use is in the new area of
stochastic neuromorphic computing and, information security and
instrumentation. Since conventional FS circuits cannot work with random
signals, we introduce a novel random frequency ratio detector, that works both
with random and periodic signals.Comment: 9 pages, 10 figure
Quantum random flip-flop based on random photon emitter and its applications
We propose, experimentally realize and study possible applications of a new
type of logic element: random flip-flop. By definition it operates similarly to
a conventional flip-flop except that it functions with probability of 1/2
otherwise it does nothing. We demonstrate one practical realization of the
random flip-flop based on optical quantum random number generator and discuss
possible usages of such a device in computers, cryptographic hardware and
testing equipment.Comment: 18 pages, 19 figure
Improved circuits for a biologically-inspired random pulse computer
We present improved circuits intended for building a universal computer based
on Random Pulse Computing (RPC) paradigm, a biologically-inspired way of
computation in which variable is represented by a frequency of a Random Pulse
Train (RPT) rather than a logic state. The RPC we mention here is also known as
"stochastic unipolar computation" in newer literature. Unlike in previous art,
where randomness is obtained from electronics noise or a pseudorandom shift
register while processing circuitry is deterministic, in our approach both
variable generation and signal processing rely on the random flip-flop (RFF)
whose randomness is derived from a fundamentally random quantum process. This
offers advantage in better precision and faster calculation.Comment: 10 pages, 14 figure
