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 ...

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 ...

Quantum computing may one day outperform classical machines in solving certain complex problems, but when and how this “quantum advantage” emerges has remained unclear. Now, researchers from Kyoto ...

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 ...

To overcome this problem, high-rate quantum codes, such as quantum low-density parity-check codes, have been considered. With this approach, the logical gates, which make calculations possible, have ...

To build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits, or qubits, create as they operate. Subscribe to our newsletter ...

Classical computing has operated as the fundamental power behind our digital world for many decades. Modern civilization relies on classical systems to operate smartphones and global financial ...

Microsoft has unveiled Majorana 1, the world’s first quantum processor built using topological core architecture, an ...

Lead author and PhD student Vassili Matsos looking at the Paul trap quantum computing device in the Quantum Control Laboratory at the University of Sydney. To build a large-scale quantum computer that ...
