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 .
By contrast, quantum computers rely on qubits (quantum bits), which essentially allow data values to exist in different states at the time -- a phenomenon known as superposition.
Way back in 2018, the company unleashed a 72-qubit quantum processor known as Bristlecone, and in early 2023, Alphabet announced a breakthrough in the quantum computing market.
This list contains quantum processors, also known as quantum processing units (QPUs). Some devices listed below have only been announced at press conferences so far, with no actual demonstrations or scientific publications characterizing the performance. Quantum processors are difficult to compare due to the different architectures and approaches.
