Computers also make mistakes. These are usually suppressed by technical measures or detected and corrected during the calculation. In quantum computers, this involves some effort, as no copy can be ...

Just like any machine, quantum computers are prone to make errors. These errors can cause the qubits to lose their quantum states, leading to inaccurate computations. To address this problem, quantum ...

In 2022, USTC researchers led by quantum physicist Pan Jianwei demonstrated the proof of principle by achieving a ...

Physicists are quietly rolling out a new generation of simulation codes that promise to do more than crunch numbers. By ...

Two-dimensional projection of a quantum spherical code composed of two copies (black and red) of the four complex dimensional Witting polytope. This code can correct up to five photon losses of any ...

Integrated quantum computing company Quantinuum Ltd. today unveiled new open-source software tools designed to accelerate software development for quantum computing with a more intuitive programming ...

China reports a quantum error correction breakthrough that could rival Google, signaling faster progress toward practical ...

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 ...

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method ...
