While most efforts focus on hardware, Qedma specializes in error mitigation software. Its main piece of software, QESEM, or quantum error suppression and error mitigation, analyzes noise patterns to suppress some classes of errors while the algorithm is running and mitigate others in post-processing.IBM itself does both quantum hardware and software, and some of its partners, like French startup Pasqal, also develop their own hardware. But it sees value as well in partnering with companies more narrowly focusing on the software layer, like Qedma and Tiger Global-backed Finnish startup Algorithmiq, its VP of Quantum. Despite their imposing presence, quantum computers are delicate beasts, and their errors are among the main bottlenecks that the quantum computing community is actively working to address. Failing this, promising applications in finance, drug discovery, and materials science may never become real.Israeli quantum startup Qedma just raised $26 million, with IBM joining in, who is leading this quantum computing race ?
