History

Rigetti Computing was founded in 2013 by Chad Rigetti, a physicist who previously worked on quantum computers at IBM, and studied under noted Yale quantum scientist Michel Devoret.[1][2] The company emerged from startup incubator Y Combinator in 2014 as a so-called "spaceshot" company.[3][4] The company also went through enterprise revenue-focused The Alchemist Accelerator in 2014.[4]

By February 2016, the company had begun testing a three-qubit (quantum bit) chip made using aluminum circuits on a silicon wafer.[5] 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.[4]

By Spring of 2017, the company was testing eight-qubit computers,[2] 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.[1]

Products and technology

Rigetti Computing is a full-stack quantum computing company, a term that indicates that the company designs and fabricates quantum chips, integrates them with a controlling architecture, and develops software for programmers to use to build algorithms for the chips.[6]

Forest cloud computing platform

The company hosts a cloud computing platform called Forest, which gives developers access to quantum processors so they can write quantum algorithms for testing purposes. The computing platform is based on a custom instruction language the company developed called Quil, which stands for Quantum Instruction Language. Quil facilitates hybrid quantum/classical computing, and programs can be built and executed using open source Python tools.[6][7] As of June 2017, the platform allows coders to write quantum algorithms for a simulation of a quantum chip with 36 qubits.[1]

Fab-1

The company operates a rapid prototyping fabrication ("fab") lab called Fab-1, designed to quickly create integrated circuits. Lab engineers design and generate experimental designs for 3D-integrated quantum circuits for qubit-based quantum hardware.[6]

Recognition

The company was recognized by X-Prize founder Peter Diamandis as being one of the three leaders in the quantum computing space, along with IBM and Google.[8] MIT Technology Review named the company one of the 50 smartest companies of 2017.[9]

Locations

Rigetti Computing is headquartered in Berkeley, California, where it hosts developmental systems and cooling equipment.[8] The company also operates its Fab-1 manufacturing facility in nearby Fremont.[1]
