What qualifies as a quantum observer?

When a quantum “observer” is watching Quantum mechanics states that particles can also behave as waves. This can be true for electrons at the submicron level, i.e., at distances measuring less than one micron, or one thousandth of a millimeter.

Does quantum mechanics need an observer?

Crucially, the theory does not need observers or measurements or a non-material consciousness. Neither do so-called collapse theories, which argue that wavefunctions collapse randomly: the more the number of particles in the quantum system, the more likely the collapse. Observers merely discover the outcome.

What are observers in physics?

The quantum mechanical observer is tied to the issue of observer effect, where a measurement necessarily requires interacting with the physical object being measured, affecting its properties through the interaction. …

What happened to the Observer newspaper?

The Observer, Sunday newspaper established in 1791, the first Sunday paper published in Britain. In 1981 it was returned to British hands when an industrialist, Roland Rowland, bought control. The Observer was purchased in 1993 by the Guardian Media Group, of which The Guardian newspaper is also a part.

Can a robot make an observation in quantum mechanics?

Yes a robot or any automaton can make an observation in quantum mechanics. Despite the speculations by many people including physicists over that last 50 years, there is no reason to believe that human consciousness plays any role in the collapse of a wave function following an observation.

What is the difference between observation and measurement in quantum mechanics?

In quantum mechanics, “observation” is synonymous with quantum measurement and “observer” with a measurement apparatus and ” observable ” with what can be measured. Thus the quantum mechanical observer does not have to necessarily present or solve any problems over and above the issue of measurement in quantum mechanics.

Can another person observe the first quantum observer?

If the observer is quantum, then another observer needs to observe the first quantum observer by the tenets of quantum mechanics. Down the road of infinite regress we go. As long as the concept of an observer can’t be made mathematically precise and unambiguous, the measurement problem will never be solved.

What is an observer in math?

While it is much easier to define observer from a philosophical point of view, the mathematical answer is that the observer is a system which manifests subjective decoherence when observed. For the definition of subjective decoherence and precise mathematical formulations, refer to this work. Are we talking quantum mechanics?
