Top 10 global quantum technology companies

Quantum computing is increasingly seeing lots of progress in the development of quantum applications, hardware, and networks. With years of development and funding on the line, there are companies at the forefront of building quantum and hybrid solutions with applications such as noise reduction of qubits and error-correction, high-fidelity performance of quantum computers, qubits development, production of quantum processing units (QPU), and many more.

These companies have led the revolution of transforming supercomputers that solve computational problems sequentially using bits to quantum computers that have the potential to solve complex computational problems on multiple quantum states using qubits. They have also funded quantum research across various institutions and fostered partnerships with other players in the industry around the globe. 

Here is a list of the top global quantum computing companies pushing the boundaries of technology.

IBM Quantum
