Nobel Prize in Physics 2022

This year's Nobel Prize in Physics rewards research into quantum mechanics - the science that describes nature at the smallest scales.

The award goes to Frenchman Alain Aspect, American John Clauser and Austrian Anton Zeilinger.

Their work should pave the way to a new generation of powerful computers and telecommunications systems that are impossible to break into.

The men will share prize money of 10 million Swedish krona (£800,000).

Nobel Prize 2022: About the research

The 2022 physics laureates’ development of experimental tools has laid the foundation for a new era of quantum technology. Being able to manipulate and manage quantum states and all their layers of properties gives us access to tools with unexpected potential.

Intense research and development are underway to utilise the special properties of individual particle systems to construct quantum computers, improve measurements, build quantum networks and establish secure quantum encrypted communication.

Nobel Prize 2022: John Clauser Contribution

This year’s Nobel Prize laureate John Clauser built an apparatus that emitted two entangled photons at a time, each towards a filter that tested their polarization. The result was a clear violation of a Bell inequality and agreed with the predictions of quantum mechanics.

Nobel Prize 2022: Alain Aspect Contribution

Alain Aspect, developed a setup to close an important loophole. He was able to switch the measurement settings after an entangled pair had left its source, so the setting that existed when they were emitted could not affect the result.

Nobel Prize 2022: Anton Zeilinger Contribution

Anton Zeilinger, 2022 Nobel Prize laureate in physics, researched entangled quantum states. His research group has demonstrated a phenomenon called quantum teleportation, which makes it possible to move a quantum state from one particle to one at a distance.

About the Nobel Prize for Physics

The Nobel Prize for Physics is awarded, according to the will of Swedish inventor and industrialist Alfred Bernhard Nobel, “to those who, during the preceding year, shall have conferred the greatest benefit on mankind” in the field of physics. It is conferred by the Royal Swedish Academy of Sciences in Stockholm.
