IBM aims for million qubit quantum computer
IBM has launched its roadmap for quantum computing, aiming to deliver a system with 1000 qubits by 2023. This will form the basis of systems with millions of qubits.
our 127-qubit IBM Quantum Eagle processor,” said Gametta. Eagle includes through-silicon vias (TSVs) and multi-level wiring to effectively fan-out a large density of classical control signals while protecting the qubits in a separated layer in order to maintain high coherence times. This will also include concurrent real-time classical compute capabilities that will allow for execution of a broader family of quantum circuits and codes.

All of this is in preparation for the 433-qubit Osprey system in 2022, to be followed by 1,121-qubit Condor processor in 2023. This will require larger cooling systems. The 3.3 x 2m (10 x  6ft) “super-fridge,” internally codenamed “Goldeneye,” is designed with a million-qubit system in mind.

“We think of Condor as an inflection point, a milestone that marks our ability to implement error correction and scale up our devices, while simultaneously complex enough to explore potential quantum advantages—problems that we can solve more efficiently on a quantum computer than on the world’s best supercomputers,” said Gambetta. › quantum-computing
