IBM Eagle is a 127-qubit quantum processor.[1][2] IBM claims that it can not be simulated by any classical computer.[3][4] It is two times bigger than China's Jiuzhang 2.[5] It was revealed on November 16, 2021 and was claimed to be the most powerful quantum processor ever made until November 2022, when the IBM Osprey overtook it with 433 qubits.[6][7][8] It is almost twice as powerful as their last processor, the 'Hummingbird', which had 65 quantum bits and was created in 2020.[6] IBM believes that the processes used in creating the 'Eagle', will be the backbone for their future processors.[6]
