The eight who reached the top

1

Max Planck

Germany · 1858–1947

Introduced energy quanta in 1900, beginning the theory underlying quantum technology.

The story

Planck presented his radiation law in Berlin after treating quantization as a mathematical device he initially found uncomfortable.

“An unwanted assumption can become the doorway to a new theory.”

John Bardeen

United States · 1908–1991

Co-invented the transistor and explained superconductivity, linking quantum theory to electronics.

The story

Bardeen remains the only person to share two Physics Nobel Prizes, for the transistor in 1956 and superconductivity in 1972.

“Fundamental understanding can produce multiple generations of hardware.”

Richard Feynman

United States · 1918–1988

Framed quantum simulation as a reason to build quantum computers.

The story

At a 1981 MIT conference, Feynman argued that classical computers struggle to simulate quantum systems because nature itself is not classical.

“Choose hardware that matches the problem’s physical structure.”

Peter Shor

United States · b. 1959

Created the factoring algorithm that gave quantum computing a concrete cryptographic consequence.

The story

Shor’s 1994 algorithm showed that a sufficiently capable quantum computer could factor large integers much faster than known classical methods.

“A single algorithm can turn a theoretical device into a strategic problem.”

David Wineland

United States · b. 1944

Pioneered laser cooling and trapped-ion precision measurements central to ion quantum systems.

The story

Wineland’s group cooled ions and manipulated their states with lasers, work recognized by the 2012 Nobel Prize.

“Precision measurement is a technology platform, not just a result.”

Michelle Simmons

United Kingdom / Australia · b. 1967

Leads silicon-quantum research pursuing atomically precise devices compatible with semiconductor methods.

The story

Her teams have used scanning tunneling microscopy to place individual phosphorus atoms in silicon structures.

“Manufacturing precision can be a computational resource.”

Jian-Wei Pan

China · b. 1970

Led major experiments in quantum communication and satellite entanglement distribution.

The story

China’s Micius satellite enabled landmark quantum-communication experiments over long distances in 2017.

“A network experiment needs infrastructure as much as elegant physics.”

Stephanie Wehner

Netherlands · b. 1977

A quantum-information scientist advancing quantum networks and their architecture.

The story

At QuTech, Wehner has helped define network-stack concepts for future quantum links rather than treating entanglement as an isolated laboratory event.

“A network becomes useful only when interfaces make experiments interoperable.”

The argument

Whether current processors demonstrate useful quantum advantage remains contested because benchmarks may not map to valuable applications.

There is also debate about whether national race rhetoric helps the field or encourages secrecy and overclaiming.
