IBM connects two quantum processors with 99% accuracy.
IBM researchers connected two 120-qubit Nighthawk R1 quantum processors, achieving an average quantum state transfer accuracy of 99%. The experiment demonstrated the potential for integrating individual superconducting chips into larger computational systems.
The results are presented in a preprint and have not yet undergone independent peer review.
How IBM Connected the Quantum Processors
One of the main challenges of quantum computers is scaling. Increasing the number of qubits on a single processor complicates their management, the connection of control electronics, and error suppression. An alternative approach involves combining several relatively small chips into one system. However, this…
