In a breakthrough that could help address a major bottleneck in practical quantum computing, ...

Quantum computers have an inconvenient problem: they're magnificently efficient at making mistakes. These marvelous machines could one day solve problems that would bring even the most powerful ...

Quantum computing just got a significant boost thanks to researchers at the University of Osaka, who developed a much more efficient way to create "magic states" a key component for fault-tolerant ...

Quantum computers hold great promise for applications from drug discovery to cybersecurity. Yet figuring out what would give quantum computers their edge over everyday "classical" computers is a ...

In the context of quantum mechanics and information, "magic" is a key property of quantum states that describes the extent to which they deviate from so-called stabilizer states. Stabilizer states are ...

Making quantum computers fault-tolerant (and scaling effective error correction to enable this) is a key barrier to a new era of quantum supremacy. A new study ...

A hybrid magic system made up of spin qubits and photons (Credit: Ying-Lin Li) This property determines whether a quantum system can outperform even the fastest classical supercomputer. Until now, ...
