@interestingengineering: Microsoft just unveiled Majorana 2 — a quantum chip with qubit lifetimes of 20 seconds, compared to microseconds on standard quantum hardware. That's a 1,000x reliability jump. But to understand why this matters, you first need to understand what a qubit actually is — not the oversimplified version, the real one. We break down how qubits work, why they keep breaking, and what Microsoft's topological approach changes. We also cover IBM's quantum roadmap, what problems quantum computers will actually solve, and why 2029 is becoming the most important year in computing. #QuantumComputing #Microsoft #Majorana2 #Qubits #IBM #QuantumTechnology #TechExplained #FutureTech #Majorana #QuantumChip
