Quantum Machines has raised $170 million in series C funding, one of the largest rounds of funding in the quantum industry.

Microsoft says it has developed a breakthrough quantum processor based on a new state of matter, giving it a clear path to achieve quantum computing’s long-term promise of solving some of the world’s most difficult problems.

The processor uses qubits that can be measured without error and are resistant to outside interference, which the company says marks a “transformative leap toward practical quantum computing.”
