  So far, several macroscopic quantum phenomena have been discovered in the
Josephson junction. Through introducing such a structure with a liquid membrane
sandwiched between two liquid metal electrodes, we had ever observed a lighting
and sound phenomenon which was explained before as discharge plasma. In fact,
such an effect also belongs to a quantum process. It is based on this
conceiving, we proposed here that an electrically controllable method can thus
be established to generate and manipulate as much photonic quantum as desired.
We attributed such electrically induced lighting among liquid metal droplets
immersed inside aqueous solution as photonic quantum effect. Our experiments
clarified that a small electrical voltage would be strong enough to trigger
blue-violet light and sound inside the aqueous solution system. Meanwhile,
thermal heat is released, and chemical reaction occurs over the solution. From
an alternative way which differs from former effort in interpreting such effect
as discharge plasma, we treated this process as a quantum one and derived new
conceptual equations to theoretically quantify this phenomenon in light of
quantum mechanics principle. It can be anticipated that given specific
designing, such spontaneously generated tremendous quantum can be manipulated
to entangle together which would possibly help mold functional elements for
developing future quantum computing or communication system. With superior
adaptability than that of the conventional rigid junction, the present
electro-photonic quantum generation system made of liquid metal droplets
structure could work in solution, room temperature situation and is easy to be
adjusted. It suggests a macroscopic way to innovate the classical strategies
and technologies in generating quantum as frequently adopted in classical
quantum engineering area.
