Researchers from QuTech have achieved a world's first in quantum internet technology. A team led by Professor Stephanie Wehner has developed a so-called link... more

Dead or alive, left-spinning or right-spinning -- in the quantum world particles such as the famous analogy of Schrödinger's cat can be all these things at the same time. An international team, together with experts from Forschungszentrum Jülich,... more

Dead or alive, left-spinning or right-spinning—in the quantum world particles such as the famous analogy of Schrödinger's cat can be all these things at the same time. An international team, including researchers from several leading American universities, together... more

In addition, they showed that the generated 18-qubit Greenberger-Horne-Zeilinger state is genuine entangled. more

Quantum computing and quantum cryptography are expected to give much higher capabilities than their classical counterparts. For example, the computation power in a quantum system may grow at a double... more

The AdS/CFT correspondence conjectures a holographic duality between gravity in a bulk space and a critical quantum field theory on its boundary. Tensor networks have come to provide toy models to understand these bulk-boundary... more

Quantum entanglement involving coherent superpositions of macroscopically distinct states is among the most striking features of quantum theory, but its realization is challenging because such states... more

Multipartite entangled states are crucial for numerous applications in quantum information science. However, the generation and verification of multipartite entanglement on fully controllable and... more

A duo of researchers at Purdue University has modified a popular theorem — called Bell’s inequality... more

For the first time, scientists have developed a practical way to measure quantum entanglement in chemical reactions. more

The Einstein, Podolsky, and Rosen (EPR) entanglement, which features the essential difference between classical and quantum physics, has received wide theoretical and experimental attentions. Recently, the desire to understand and create quantum entanglement between particles such as spins,... more

Scientists have long suspected that a quantum phenomenon might play a role in photosynthesis and other chemical reactions of nature, but don't know for... more

Many famous experiments have shown that the simple act of observing a quantum system can change the properties of the system. This phenomenon, called the "observer effect," appears, for example, when Schrödinger's... more

A quantum spin liquid is a state of matter where unpaired electrons’ spins, although entangled, do not show... more
