Microsoft introduced its first quantum computing chip on Wednesday, suggesting that quantum computing could be realized in “years, not decades.” The company’s Majorana 1 chip integrates eight qubits—the essential units of quantum computing—onto a compact, sticky-note-sized piece of hardware. Majorana 1 is the first Quantum Processing Unit (QPU) based on a topological core, specifically designed to scale up to a million qubits within a single chip.
