WHAT IS QUANTUM ENTANGLEMENT? A PHYSICIST EXPLAINS EINSTEIN’S ‘SPOOKY ACTION AT
A DISTANCE’

A multitude of experiments have shown the mysterious phenomena of quantum
mechanics to be how the universe functions. The scientists behind these
experiments won the 2022 Nobel Prize in physics.

When two particles are entangled, the state of one is tied to the state of the
other.

The 2022 Nobel Prize in physics recognized three scientists who made
groundbreaking contributions in understanding one of the most mysterious of all
natural phenomena: quantum entanglement.

In the simplest terms, quantum entanglement means that aspects of one particle
of an entangled pair depend on aspects of the other particle, no matter how far
apart they are or what lies between them. These particles could be, for example,
electrons or photons, and an aspect could be the state it is in, such as whether
it is “spinning” in one direction or another.

The strange part of quantum entanglement is that when you measure something
about one particle in an entangled pair, you immediately know something about
the other particle, even if they are millions of light years apart. This odd
connection between the two particles is instantaneous, seemingly breaking a
fundamental law of the universe. Albert Einstein famously called the phenomenon
“spooky action at a distance.”

Having spent the better part of two decades conducting experiments rooted in
quantum mechanics, I have come to accept its strangeness. Thanks to ever more
precise and reliable instruments and the work of this year’s Nobel winners,
Alain Aspect, John Clauser and Anton Zeilinger, physicists now integrate quantum
phenomena into their knowledge of the world with an exceptional degree of
certainty.

However, even until the 1970s, researchers were still divided over whether
quantum entanglement was a real phenomenon. And for good reasons – who would
dare contradict the great Einstein, who himself doubted it? It took the
development of new experimental technology and bold researchers to finally put
this mystery to rest.

According to quantum mechanics, particles are simultaneously in two or more
states until observed – an effect vividly captured by Schrödinger’s famous
thought experiment of a cat that is both dead and alive simultaneously.

EXISTING IN MULTIPLE STATES AT ONCE

To truly understand the spookiness of quantum entanglement, it is important to
first understand quantum superposition. Quantum superposition is the idea that
particles exist in multiple states at once. When a measurement is performed, it
is as if the particle selects one of the states in the superposition.

For example, many particles have an attribute called spin that is measured
either as “up” or “down” for a given orientation of the analyzer. But until you
measure the spin of a particle, it simultaneously exists in a superposition of
spin up and spin down.

There is a probability attached to each state, and it is possible to predict the
average outcome from many measurements. The likelihood of a single measurement
being up or down depends on these probabilities, but is itself unpredictable.

Though very weird, the mathematics and a vast number of experiments have shown
that quantum mechanics correctly describes physical reality.

TWO ENTANGLED PARTICLES

Albert Einstein, Boris Podolsky and Nathan Rosen pointed out an apparent problem
with quantum entanglement in 1935 that prompted Einstein to describe quantum
entanglement as ‘spooky action at a distance.’
Sophie Dela/Wikimedia Commons

The spookiness of quantum entanglement emerges from the reality of quantum
superposition, and was clear to the founding fathers of quantum mechanics who
developed the theory in the 1920s and 1930s.

To create entangled particles you essentially break a system into two, where the
sum of the parts is known. For example, you can split a particle with spin of
zero into two particles that necessarily will have opposite spins so that their
sum is zero.

In 1935, Albert Einstein, Boris Podolsky and Nathan Rosen published a paper that
describes a thought experiment designed to illustrate a seeming absurdity of
quantum entanglement that challenged a foundational law of the universe.

A simplified version of this thought experiment, attributed to David Bohm,
considers the decay of a particle called the pi meson. When this particle
decays, it produces an electron and a positron that have opposite spin and are
moving away from each other. Therefore, if the electron spin is measured to be
up, then the measured spin of the positron could only be down, and vice versa.
This is true even if the particles are billions of miles apart.

This would be fine if the measurement of the electron spin were always up and
the measured spin of the positron were always down. But because of quantum
mechanics, the spin of each particle is both part up and part down until it is
measured. Only when the measurement occurs does the quantum state of the spin
“collapse” into either up or down – instantaneously collapsing the other
particle into the opposite spin. This seems to suggest that the particles
communicate with each other through some means that moves faster than the speed
of light. But according to the laws of physics, nothing can travel faster than
the speed of light. Surely the measured state of one particle cannot
instantaneously determine the state of another particle at the far end of the
universe?

Physicists, including Einstein, proposed a number of alternative interpretations
of quantum entanglement in the 1930s. They theorized there was some unknown
property – dubbed hidden variables – that determined the state of a particle
before measurement. But at the time, physicists did not have the technology nor
a definition of a clear measurement that could test whether quantum theory
needed to be modified to include hidden variables.

John Bell, an Irish physicist, came up with the means to test the reality of
whether quantum entanglement relied on hidden variables.

DISPROVING A THEORY

It took until the 1960s before there were any clues to an answer. John Bell, a
brilliant Irish physicist who did not live to receive the Nobel Prize, devised a
scheme to test whether the notion of hidden variables made sense.

Bell produced an equation now known as Bell’s inequality that is always correct
– and only correct – for hidden variable theories, and not always for quantum
mechanics. Thus, if Bell’s equation was found not to be satisfied in a
real-world experiment, local hidden variable theories can be ruled out as an
explanation for quantum entanglement.

The experiments of the 2022 Nobel laureates, particularly those of Alain Aspect,
were the first tests of the Bell inequality. The experiments used entangled
photons, rather than pairs of an electron and a positron, as in many thought
experiments. The results conclusively ruled out the existence of hidden
variables, a mysterious attribute that would predetermine the states of
entangled particles. Collectively, these and many follow-up experiments have
vindicated quantum mechanics. Objects can be correlated over large distances in
ways that physics before quantum mechanics can not explain.

Importantly, there is also no conflict with special relativity, which forbids
faster-than-light communication. The fact that measurements over vast distances
are correlated does not imply that information is transmitted between the
particles. Two parties far apart performing measurements on entangled particles
cannot use the phenomenon to pass along information faster than the speed of
light.

Today, physicists continue to research quantum entanglement and investigate
potential practical applications. Although quantum mechanics can predict the
probability of a measurement with incredible accuracy, many researchers remain
skeptical that it provides a complete description of reality. One thing is
certain, though. Much remains to be said about the mysterious world of quantum
mechanics.
