From 1981, when the idea of computing with quantum principles first appeared, to today, as quantum computers move closer to computing while fixing their own errors.

Google runs a quantum calculation whose result can be checked again
Google announced that it ran a calculation called "Quantum Echoes" on Willow. The result can be checked again on another quantum computer, and the calculation is far faster than a supercomputer.
Nobel Prize in Physics honors superconducting circuit research
John Clarke, Michel Devoret and John Martinis won the Nobel Prize in Physics for showing quantum tunneling in an electrical circuit. This work is the root of today's superconducting qubits.
Google showed on its chip Willow that errors fall as the group of qubits gets larger. This is a key step toward a quantum computer that computes while fixing errors.
Researchers from Harvard, MIT and QuEra reported in Nature that they ran calculations with 48 "logical qubits", groups of qubits combined to resist errors.
Nobel Prize in Physics honors quantum entanglement experiments
Alain Aspect, John Clauser and Anton Zeilinger won the Nobel Prize in Physics for experiments with entangled particles of light (photons) that opened the way for quantum information science.
Google reported in Nature that its 53-qubit chip Sycamore did in about 200 seconds a calculation that would have taken a supercomputer of the time a very long while. IBM argued against that comparison.
D-Wave unveils the "first commercial quantum computer"
D-Wave announced the D-Wave One, which uses "quantum annealing" to solve certain optimization problems. It works differently from a general-purpose quantum computer that can do many kinds of calculations.
Peter Shor published a method showing that a quantum computer could factor large numbers quickly. The worry that today's internet encryption must be replaced started here.
At a physics of computation conference at MIT, Richard Feynman said that to imitate nature properly, we need a machine that computes with quantum principles.
The events were chosen and described by AI, and each date was checked against the source listed with it (an official announcement, a paper or Wikipedia). Dates follow the source: Korean events in Korean time, others in local time or UTC, so a day's difference is possible. The timeline does not grow by itself; new events are checked and added by hand.
