There are two main camps in the quantum computing development, says Ashish Nadkarni, Program Vice President of Computing Platforms, Worldwide Infrastructure at IDC. In the first camp are entrenched players from the world of classical computing. And in the second are quantum computing startups.\n\u201cIt\u2019s a highly fragmented landscape,\u201d Nadkarni says. \u201cEach company has its own approach to building a universal quantum computer and delivering it as a service.\u201d\n\nClassic-computing vendors pioneer quantum computing\nAlong with IBM, other classical computing companies staking a claim in the emerging field of quantum computing include:\nAlphabet Inc.\u2019s Google recently said it\u2019s \u201ccautiously optimistic\u201d that its new Bristlecone quantum processor, with 72 qubits, can achieve \u201cquantum supremacy.\u201d Quantum supremacy, or quantum advantage as some call it, will happen when a quantum computer can solve a problem that a classical supercomputer can\u2019t.\nIntel announced its 49-qubit quantum test chip named Tangle Lake at CES 2018. The company said Tangle Lake \u201crepresents progress toward Intel\u2019s goal of developing a complete-quantum computing system.\u201d\nMicrosoft CEO Satya Nadella has said that quantum computing, along with AI and augmented reality, are the three technologies most important to its future. Among Microsoft\u2019s quantum-computing efforts, the company is developing a quantum computer that will be a part of its Azure cloud within five years. And it has released a free preview version of its Quantum Development Kit, for those who want to start writing applications for quantum computers.\nQuantum computing startups\nRigetti Computing, founded in 2013, is a \u201cfull-stack quantum-computing company,\u201d meaning that it builds hardware and software to store and process quantum information. The company also offers a quantum-computing platform called Forest.\nD-Wave Systems, Inc. became the world\u2019s first company to actually sell quantum computers in 2011. The cost at the time: $10 million. Founded in 1999, the Canadian company is among the oldest quantum-computing startups.\nZapata Computing, among the newest quantum computing startups, was spun out of Harvard University and formally launched in May 2018. The company is focused on developing quantum computing algorithms and software that will support hardware from Rigetti, IBM and others. Al\u00e1n Aspuru-Guzik, a noted quantum computer algorithm developer and Harvard University professor, is a co-founder.\nIt\u2019s worth noting that IBM is partnering with a variety of quantum computing startups, including Zapata Computing and 1Qbit.\nQuantum Computing Report offers a deeper dive into quantum computing startups.
