How Microsoft Quantum Built Qubits 1,000× More Reliable

Quantum ZeitgeistJune 2, 20264 min read

Microsoft Quantum’s Majorana 2 processor boasts qubits 1,000x more reliable thanks to a lead-based material stack, extending qubit lifetimes to 20+.

Microsoft Quantum has achieved a substantial leap in quantum computing stability with its new Majorana 2 processor, creating qubits that are 1,000 times more reliable than its previous unit. This improvement stems from a key materials science innovation: replacing aluminum with lead in the processor’s construction, effectively doubling the topological gap and bolstering qubit robustness. The resulting qubits now maintain quantum information for an average of 20 seconds, with some lasting over a minute, a critical advancement for performing complex calculations. “Majorana…
