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 ...

The company said it is able to reduce error rates in its quantum computing capabilities by 1,000-fold thanks to four-dimensional geometric codes. Quantum Computing ...

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 ...

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 ...

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, ...

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.

The conventional approach to quantum error correction is typically based on encoding a single logical qubit—the qubit being the equivalent of a bit on a classical computer—onto many entangled physical ...
