In the world of quantum computing, the Hilbert space dimension—the measure of the number of quantum states that a quantum computer can access—is a prized possession. Having a larger Hilbert space ...

Quantum computers still face a major hurdle on their pathway to practical use cases: their limited ability to correct the arising computational errors. To develop truly reliable quantum computers, ...

On Tuesday, Microsoft made a series of announcements related to its Azure Quantum Cloud service. Among them was a demonstration of logical operations using the largest number of error-corrected qubits ...

Technically, Carbon code is a stabilizer code of the Calderbank-Shor-Steane variety, which is a quantum error-correction code. “It encodes two logical qubits among 12 physical qubits,” she says.

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 ...

The latest machine on IBM’s quantum computing roadmap, Heron, has been given a hardware and software boost as the company pushes towards its goal of error ...
