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 ...

Astronaut John Glenn was wary about trusting a computer. It was 1962, early in the computer age, and a room-sized machine had calculated the flight path for his upcoming orbit of Earth — the first for ...

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 Google-led research team has demonstrated a surface-code logical qubit operating below the error-correction threshold, ...

Many error-correcting codes (ECCs) are proposed in the industry’s literature for correcting bit errors present in the received data. We will discuss Hamming codes that are used to correct singlebit ...
