This article lists the companies worldwide engaged in the development of quantum computing, quantum communication and quantum sensing. Quantum computing and communication are two sub-fields of quantum information science , which describes and theorizes information science in terms of quantum physics .
QuEra Computing was founded by Mikhail Lukin, Vladan Vuletić, Markus Greiner, Dirk Englund, Nathan Gemelke, and John Pena in 2018. [2]Prior to QuEra’s founding, research into using and controlling neutral atoms had already started in 2015 at Harvard and MIT, culminating in a 51-qubit machine [6] which later led to the development of a 256-qubit machine.
D-Wave Quantum Systems Inc. is a quantum computing company with locations in Palo Alto, California and Burnaby, British Columbia. D-Wave claims to be the world's first company to sell computers that exploit quantum effects in their operation. [ 3 ]

In June, the company announced the release of Forest 1.0, a quantum computing platform designed to enable developers to create quantum algorithms. [2] This was a major milestone. In October 2021, Rigetti announced plans to go public via a SPAC merger , with estimated valuation of around US$1.5 billion.
In 2016, they brought on David Moehring from IARPA—where he was in charge of several quantum computing initiatives [10] [3] —to be the company's chief executive. [2] In 2017, they raised a $20 million series B, led by GV (formerly Google Ventures) and New Enterprise Associates, the first investment GV has made in quantum computing ...
Quantum information processing, also called quantum computing, theoretically is known to offer dramatic speed-ups and more complete answers for some combinatorial computing problems. Quantum annealing is a branch of quantum computing whose advantages over classical computing are being investigated. [7] In quantum annealing, problems are encoded ...
Quantinuum is a quantum computing company formed by the merger of Cambridge Quantum and Honeywell Quantum Solutions. [1] The company's H-Series trapped-ion quantum computers set the highest quantum volume to date of 1,048,576 in April 2024. [ 2 ]
