In the previous article titled “The Basics: How Quantum Computers Work and Where the Technology is Heading,” we provided an overview of foundational quantum computing concepts, including qubits ...

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

Quantum computers use qubits, which are based on quantum physics, allowing them to solve complex problems far faster than ...

Quantum hardware is starting to hit a wall that has little to do with flashy new qubit designs and everything to do with how precisely those qubits are tuned. As devices scale, tiny errors in charge ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

Conventional computers work by performing operations on bits encoded in silicon. But no one is really sure how qubits will be encoded in the quantum computers of the future. Half a dozen or so ...

Quantum computers hold the potential to revolutionize the possibilities for solving difficult computational problems that would take classical computers many years to resolve. But for those computers ...

Researchers at QuTech in Delft, The Netherlands, have developed a new chip architecture that could make it easier to test and scale up quantum processors based on semiconductor spin qubits Researchers ...

Chemistry professor Danna Freedman crafts “designer molecules” for quantum information science. It all began with a simple origami model. As an undergrad at Harvard, Danna Freedman went to a professor ...

Developing technology that allows quantum information to be both stable and accessible is a critical challenge in the development of useful quantum computers that operate at scale. Research published ...

In a scene from the movie Gladiator, Roman emperor Marcus Aurelius, worried about the fragility of his empire, tells his general, Maximus: “There was once a dream that was Rome. You could only whisper ...
