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]
