IBM and the University of Chicago Demonstrate Quantum Supremacy with 70 Logical Qubits

On July 30, a research team from IBM and the University of Chicago announced that they had successfully completed a computation using a quantum computer that classical computers cannot perform, in a manner that allows for the verification of the results' accuracy. The team used a new error correction method to encode 70 logical qubits and completed the computation in about 15 minutes. A logical qubit refers to a unit of information that combines multiple physical qubits to enable error correction. Unlike regular qubits...
