Imagine an internet where your data can’t be stolen, your messages are completely private and online security is unbreakable. That’s the promise of quantum internet: a futuristic technology that could ...

Every online bank transfer, private message and Bitcoin transaction rests on the assumption that some math problems are ...

Just like any machine, quantum computers are prone to make errors. These errors can cause the qubits to lose their quantum states, leading to inaccurate computations. To address this problem, quantum ...

A qubit is sort of like a spinning coin before it lands, but this state makes it more sensitive to outside forces, such as ...

Quantum computing, once the realm of science fiction, could bring massive economic gains. But it also threatens to upend national security, and governments are racing to prepare. Quantum computers ...

Surface codes are well-suited to the superconducting circuit-based quantum computers being developed by Google and IBM, whose physical qubits are arranged in exactly this kind of grid. But each ...

(Bloomberg) -- Four decades ago, physicists were theorizing that the mind-bending mechanics of quantum physics could be ...

The beautiful mathematical and geometric structure of the code is remarkable, as most high-rate quantum codes have complicated structures. Goto emphasizes that in order for the new codes to result in ...

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 method ...

On Tuesday, IBM released its plans for building a system that should push quantum computing into entirely new territory: a system that can both perform useful calculations while catching and fixing ...

Quantum computers, systems that process information leveraging quantum mechanical effects, could soon outperform classical computers on some complex computational problems. These computers rely on ...

Quantum computers are expected to solve some problems beyond the reach of the most powerful supercomputers imaginable. Reaching this milestone has been dubbed "quantum supremacy." But whether quantum ...
