In a paper published in the journal Nature Communications, researchers introduced a family of three-dimensional topological codes designed for optimal quantum information storage. These codes ...

Scientists have developed an exact approach to a key quantum error correction problem once believed to be unsolvable, and have shown that what appeared to be hardware-related errors may in fact be due ...

Named after its inventors, the GKP code was proposed in 2001 as a way to encode a qubit, the quantum equivalent of a bit, in a harmonic oscillator—a system that resembles a pendulum.

Find the IoT board you’ve been searching for using this interactive solution space to help you visualize the product selection process and showcase important trade-off decisions.

The codes achieve an encoding rate—a number that indicates the ratio between logical and physical qubits—of up to 30% which Goto says appears to be the world's highest among the codes used for ...

There are similarities and differences between what the company is talking about today and IBM's recent update of its roadmap ...

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a ...

Theoretical physicists at RIKEN have made a key advance in quantum computing, using AI to improve the Gottesman-Kitaev-Preskill (GKP) code, a vital error-correction method.

Xanadu (xanadu.ai), a leader in photonic quantum computing, has published a research article in the peer-reviewed journal Physical Review Letters, demonstrating how photonic qubits can be used to ...

Quantum is smart. The progression toward embryonic quantum computing services represents a shift (you know what kind) in terms of the amount of intelligence we can apply to computing, data ...

A way to greatly enhance the efficiency of a method for correcting errors in quantum computers has been realized by theoretical physicists at RIKEN. This advance could help to develop larger, more ...
