Yale physicists introduce the transmon, the qubit later used by IBM and Google
Oct 12, 2007
Jens Koch, Robert Schoelkopf and colleagues at Yale describe the transmon, a superconducting qubit designed to be far less sensitive to electrical charge noise than the earlier "Cooper pair box". Posted online in February 2007, the paper was published in Physical Review A that October.
Why it matters
The transmon became the workhorse of superconducting quantum computing: IBM says it went on to be at the heart of quantum computers from IBM, Google and Rigetti.

“In 2007, a team at Yale found a way to combine some of these approaches to overcome their individual shortcomings, naming the new design the "transmon qubit." The transmon qubit would go on to be at the heart of many companies' efforts to develop quantum computers, including IBM Quantum, Google AI, and Rigetti Computing.”
