A new technical paper titled “Quantum error correction below the surface code threshold” was published by researchers at Google and other collaborators.

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 ...

“High-fidelity control of quantum bits is paramount for the reliable execution of quantum algorithms and for achieving fault tolerance—the ability to correct errors faster than they occur. The central ...

The authors execute surface codes on a 72-qubit processor and a 105-qubit processor. Each time the code distance is increased from 3 to 5 to 7, the logical error rate is halved. This exponential ...

How do you construct a perfect machine out of imperfect parts? That’s the central challenge for researchers building quantum computers. The trouble is that their elementary building blocks, called ...

For the first time ever, a logical qubit meets all criteria, demonstrating that Quantum Error Correction is effective. Here is the link to the research paper. Many ...

Quantum computers, systems that process information leveraging quantum mechanical effects, could soon outperform classical computers on some complex computational problems. These computers rely on ...

RIKEN scientists tap into AI to find a smarter method for fixing quantum errors, cutting resource demands for stable quantum machines. Theoretical physicists at RIKEN have made a key advance in ...

Engineers in Sydney have demonstrated a quantum integrated circuit made up of just a few atoms. By precisely controlling the quantum states of the atoms, the new processor can simulate the structure ...
