P False ½ 1 2 τ f x 100 %: (4.6)

Using these equations, the probability fraction of seeing a true at f 0 is finite,
although it is small (it is 2 0 where without

doubt a 100 % chance of seeing a false occurs. Likewise at f 1 there is a 100 %
chance of reading a true, assuming a sampling window whose width is

τ /T o ). This topic generally assumes f 0 !

δ ¼ 2 τ .

Frequency Control

Frequency is proposed to be controlled by circuit delay. Signal delay is regulated by
the length of the circuit, membrane capacitance, and such current-charging
parameters as the density of conductive pores (or ion channels) in an unmyelinated
neural conductor and also by local ionic concentrations. Neurotransmitters may
also have a role. Wide-ranging delay control is not used in this topic; delay is
modified only in situations in which delay must be increased very slightly. If
needed, the proper combinations of parameters for delay control may be found by
simulation. Figure 4.10 visualizes an idealized delay segment under control of a
signal labeled y.
Variable frequency is a theoretical property of a simulated qubit but is not used
very much in this topic. However, controlled toggling, which is one of the main
tasks of simulated qubits, is used a lot. To accomplish a toggle, the system simply
needs to stop pulse cycling to achieve f 0 !

0 and to trigger pulse cycling with
minimum delay in the loop for the highest frequency f 1 .
