We are all connected,
We will never die.
Like Schrodinger's Cat,
We will all be dead,
And still alive.

In physics, a quantum (plural: quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. The fundamental notion that a physical property may be "quantized" is referred to as "the hypothesis of quantization".

Schrödinger's cat is a thought experiment, sometimes described as a paradox, devised by Austrian physicist Erwin Schrödinger in 1935. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects.

Schrödinger's cat is "quantum" nothing and is merely a thought experiment. It is only alive/dead until it is observed/reacted, then it is one or the other. Opening the box breaks the thought experiment.

However, we may be alive after we die because the atoms that make up our bodies still have quantum action until they freeze solid at true absolute zero.
So basically, our higher life functions cease but the material that is us continues in quantum reactions.

An interpretation of quantum mechanics is an attempt to explain how the mathematical theory of quantum mechanics corresponds to reality. Although quantum mechanics has held up to rigorous and extremely precise tests in an extraordinarily broad range of experiments, there exist a number of contending schools of thought over their interpretation. These views differ on such fundamental questions as whether quantum mechanics is deterministic or random, which elements of quantum mechanics can be considered "real", and what is the nature of measurement, among other matters.

Despite nearly a century of debate and experiment, no consensus has been reached amongst physicists and philosophers of physics concerning which interpretation best represents reality.
