Quantum computers may slam into hard architectural walls long before they can crack the encryption protecting online banking, ...

Carbon code is different, says Svore. “We do not consider the Carbon code to be an LDPC code,” she says. Technically, Carbon code is a stabilizer code of the Calderbank-Shor-Steane variety, which is a ...

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 ...

The number and volume of warnings about a post-quantum cryptography (PQC) world are rising, as governments, banks, and other entities prepare for a rash of compromised data and untrustworthy digital ...

These novel error-correction codes can handle quantum codes with hundreds of thousands of qubits, potentially enabling large-scale fault-tolerant quantum computing, with applications in diverse fields ...

A Google-led research team has demonstrated a surface-code logical qubit operating below the error-correction threshold, showing that logical errors can fall rapidly as the code scales up. The ...

The company says it has cracked the code for error correction and is building a modular machine in New York state. IBM announced detailed plans today to build an ...

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 ...
