In 2025, researchers unveiled the first topological quantum processor, an 8-qubit device using Majorana particles. D-Wave’s Advantage quantum annealing computer solved a complex magnetic simulation in minutes, a problem that would take classical supercomputers millions of years. In late 2024 Google debuted the 105-qubit Willow superconducting chip with unprecedented error-correction performance. IBM crossed the 1,000-qubit milestone with its Condor processor. IonQ surpassed 99.9% two-qubit fidelity on a prototype trapped-ion system. PsiQuantum announced ultra-low-loss photonic chips and detectors in 2025 and aims for a million-qubit fault-tolerant photonic computer in the second half of the 2020s. D-Wave is upgrading to a 7,000-qubit
