Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information ...

Duplicating the information held in quantum computers was thought to be impossible thanks to the no-cloning theorem, but researchers have now found a workaround ...

A team in China has demonstrated the simultaneous teleportation of multiple sideband qumodes in a continuous-variable system, overcoming a longstanding technical barrier.

New evidence suggests a rare triplet superconductor may help quantum computers stay in sync by preserving electron spin ...

Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers ...

Scientists have developed a new way to read the hidden states of Majorana qubits, which store information in paired quantum modes that resist noise. The results confirm their protected nature and show ...

Quantum computing technology is complex, getting off the ground and maturing. There is promise of things to come. potentially ...

Researchers at the University of Tokyo have identified a precise sweet spot where quantum reservoir computing, a machine learning approach that treats quantum systems as computational engines, reaches ...

Researchers in Berlin have teleported quantum data across a 19-mile loop of commercial fiber ...
