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 ...

In 1950 Bell Labs researcher Richard W. Hamming made a discovery that would lay an important foundation for the entire modern computing and communications industries. He had invented a code for ...

Unlike binary bits of information in ordinary computers, “qubits” consist of quantum particles that have some probability of being in each of two states, designated |0 and |1 , at the same time. When ...

The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness. Unlike binary bits of information in ordinary computers, “qubits” consist ...

Scalable quantum technologies require the ability to maintain and manipulate coherent quantum states over an arbitrarily long period of time. It is problematic then that the small quantum systems that ...

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 ...

Researchers at Google Quantum AI and collaborators have developed a quantum processor with error rates that get progressively smaller as the number of quantum bits ...

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 ...

For the uninitiated, low-density parity-check (LDPC) code is an error correction code (ECC) that is used to both detect and correct errors on data that is transmitted ...
