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 ...

A research team has created a quantum logic gate that uses fewer qubits by encoding them with the powerful GKP error-correction code. By entangling quantum vibrations inside a single atom, they ...

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 ...

Google's quantum chip Willow is a step change in quantum computing (Photo illustration by VCG/VCG via Getty Images) The Willow team claim that it can perform a complex calculation in just five minutes ...

Quantum dynamics—the study of how particles behave and interact in a quantum system—has long fascinated physicists due to its puzzling and sometimes bizarre behaviors. Unlike classical systems, where ...

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 ...
