Quantum computing is still in its infancy, easily beaten by traditional computers. One of the biggest challenges? The fact that quantum bits — qubits — are much more fragile than the bits in silicon ...

A bosonic qubit developed by Nord Quantique. Made of aluminum, these cavities now contain two tiny "poles", each operating at a different frequency. These additional ...

Last month I showed how coding and error correction allows next-generation broadcast technologies such as DVB-T2 and DVB-NGH to achieve performance very close to the ...

Although the first prototypes of quantum computers already exist, they are still very prone to errors. In order to be able to solve relevant problems with them in the future, research groups are ...

Following up on Microsoft’s announcement of a qubit based on completely new physics, Amazon is publishing a paper describing a very different take on quantum computing hardware. The system mixes two ...

Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

Forbes contributors publish independent expert analyses and insights. Paul-Smith Goodson is an analyst covering quantum computing and AI. Microsoft and Quantinuum quantum computing researchers just ...

Error Correcting Code (ECC) technology, such as Low-Density Parity Check codes, has been around longer than most of you reading this have been alive. The reason is ...
