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 ...

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

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 ...

Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform ...

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

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

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 ...

A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out.

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 ...

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