Rigetti Computing

Rigetti Computing, Inc. is a Berkeley, California-based developer of quantum integrated circuits used for quantum computers. The company also develops a cloud platform called Forest that enables programmers to write quantum algorithms. History Rigetti Computing was founded in 2013 by Chad Rigetti, a physicist who previously worked on quantum computers at IBM, and studied under Michel Devoret. The company emerged from startup incubator Y Combinator in 2014 as a so-called "spaceshot" company. The company also went through enterprise revenue-focused The Alchemist Accelerator in 2014. By February 2016, the company had begun testing a three-qubit (quantum bit) chip made using aluminum circuits on a silicon wafer. In March, the company raised Series A funding of US$24 million in a round led by Andreessen Horowitz. In November, the company raised Series B funding of $40 million in a round led by investment firm Vy Capital, along with additional funding from Andreessen Horowitz and other investors. Y Combinator was a smaller investor in both rounds. By Spring of 2017, the company was testing eight-qubit computers, and in June, the company announced the public beta availability of a quantum cloud computing platform called Forest 1.0, which allows developers to write quantum algorithms.
