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 ...

As memory bit cells of any type become smaller, bit error rates increase due to lower margins and process variation. This can be dealt with using error correction to ...

"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

Given three-bit corrections, for example, one could elect to use two of those bits for repairing errors and one bit for run-time reading noise. This creates some room for push and pull between the ...

Surface code: illustration of how error correction works for bit and phase flips. The measure qubits on light blue backgrounds check for phase flip errors while the ...

Extended lifetime Quantum information is protected by encoding it in a more complicated system, such as the “GKP state”. (Courtesy: Volodymyr Sivak, Yale University) A team of researchers at Yale ...

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 ...

If you’ve ever sent a text message, played a CD, or stored a file in the cloud, you’ve benefited from error correction. This revolutionary idea dates back to the ...

Errors and mistakes are common in the classroom and in education. And I’ve published many posts about them. Today, educators share their strategies for handling errors made by students in their ...
