D-Wave Quantum said Wednesday that it had not only achieved “quantum supremacy,” but had done so using a practical problem, marking an industry first. The quantum-computing company said its Advantage2 system solved a problem in 20 minutes that would take one of the world’s most powerful supercomputers nearly 1 million years to complete.

Microsoft has introduced Majorana 1, a quantum chip with a "Topological Core" architecture, potentially enabling powerful quantum computers within years instead of decades. The breakthrough stems from a newly developed material called a topoconductor,
