It Seems Albert Einstein Was Wrong About Quantum Mechanics

Quantum mechanics and Albert Einstein's theories are complex subjects. Let's jump in, agreeing that quantum mechanics are based on probabilities that occur in the smallest aspects of the known universe, called the "sub-atomic."

Albert Einstein's initial experiment, observed that if a single light particle — or photon — was split into two beams, it could have measurable wave functions in numerous locations, but the particle itself could only be detected in one location.

"Einstein never accepted orthodox quantum mechanics and the original basis of his contention was this single-particle argument," said Griffith University physicist Howard Wiseman.
Einstein was unhappy with his theory and could not imagine a universe based on uncertainty, stating that "God does not play dice with the universe." However, it appears that his disparagement was wrong.

Griffith University have devised an experiment that confirms Einstein's original idea.

"Einstein's view was that the detection of the particle only ever at one point could be much better explained by the hypothesis that the particle is only ever at one point, without invoking the instantaneous collapse of the wave function to nothing at all other points.

"However, rather than simply detecting the presence or absence of the particle, we used homodyne measurements enabling one party to make different measurements and the other, using quantum tomography, to test the effect of those choices.

"Through these different measurements, you see the wave function collapse in different ways, thus proving its existence and showing that Einstein was wrong.

"The new study has demonstrated a new and more rigorous way of testing for single particle entanglement.

"Having a way of verifying entanglement, which requires the least amount of trust, is a potentially useful tool."

Professor Wiseman also said Albert Einstein was way ahead of his time, even though his first instincts on quantum mechanics turned out to be wrong.
"These thought experiments, that we're only really able to address now, (have) pushed the development of the technology."
Proving the notion of quantum entanglement is great, but what does this mean in terms of our everyday lives?

Being able to predict how light particles behave at the sub-atomic level creates the opportunity for it to be used in communications. Quantum computing is already taking huge leaps forward, as this theory allows computing engineers to explore creating devices that can crunch numbers and send data at the speed of light.

This old theory of Einstein's will push forward the boundaries of the technology industry once more, particularly the fields of security, supercomputing, and telecommunications.
