IBM Says Quantum Chip Could Beat Standard Chips in Two Years
IBM envisions a world in which some parts of a computing application run on traditional chips and some parts run on quantum chips, depending on what works best for each task.

IBM on Monday said it has designed a new quantum computing chip that its executives believe will let quantum systems start to outperform classical computers at some tasks within the next two years.
The company said that its "Eagle" computing chip has 127 so-called "qubits," which can represent information in quantum form. Classical computers work using "bits" that must be either a 1 or 0, but qubits can be both a 1 and a 0 simultaneously.
That fact could one day make quantum computers much faster than their classical counterparts, but qubits are exceedingly hard to build and require huge cryogenic refrigerators to operate correctly. While Apple Inc's newest M1 Max chip has 57 billion transistors—a rough proxy for bits—IBM says that its new Eagle chip is the first to have more than 100 qubits.
