Google's Willow quantum chip, with 105 qubits, enhances AI and quantum applications, boosting sentiment. Despite competitors IBM (156 qubits) and Microsoft (topological qubits), Google leads when ...

There was a time, back in the early days of computing, when we had vacuum tubes, relays, mechanical gears plus several different types of analog computers. We’re kind of in that same era today ...

The xz-planes represent qubit layers, while the yz- and xy-planes represent X-check and Z-check layers. Topological defect lines connect these layers to enforce the X and Z checks, using specified ...

How do you construct a perfect machine out of imperfect parts? That’s the central challenge for researchers building quantum computers. The trouble is that their elementary building blocks, called ...

This announcement comes at a time when Google has faced criticism for slowing down in innovation and losing relevance, ...

That quiet place may be found in a new arena—topological quantum states ... quantum information can be stored in a pair of spatially separated MZMs—a Majorana qubit—which is resistant to fault ...

Optimal control of two qubits via a single cavity drive in circuit quantum electrodynamics Scalable and robust quantum computing on qubit arrays with fixed coupling. Topological superconductors and ...
