**Researchers send entangled qubit states through a communication channel for the first time**

The results, published February 24, 2021 in Nature, could help make quantum computing more feasible and could lay the groundwork for future quantum communication networks. In a breakthrough for quantum computing, University of Chicago researchers have sent entangled…

**Cutting-Edge Quantum Collaboration Gives New Gravity to the Mysteries of the Universe**

The other authors are: Richard Howl, Vlatko Vedral (Oxford and Singapore), Devang Naik (CNRS, Bordeaux), Marios Christodoulou (Hong Kong and Oxford), Carlo Rovelli (Marseille) and Aditya Iyer (Oxford). Their research “Non-Gaussianity as a signature of a quantum theory of…

**Physicists Need to Be More Careful with How They Name Things**

Tamer alternatives such as “quantum advantage,” “quantum computational supremacy” and even “quantum ascendancy” have been proposed, but none have managed to supplant Preskill’s original term. But the context of “quantum supremacy,” which Pinker neglects, is that of a historically white,…

**Quantum collaboration gives new gravity to the mysteries of the universe**

During this time, they have come up with two fundamentally contrasting approaches, called ‘quantum gravity’ and ‘classical gravity’. Physicists would then, after more than a hundred years of research, finally have information on the true overarching, fundamental theory of nature….

**Microsoft researcher dials back quantum computing claims**

“We are confident that scaled quantum computing will help solve some of humanity’s greatest challenges, and we remain committed to our investments in quantum computing,” Kouwenhoven said. The particle, they said, could be used to create much more stable qubits, the basic units of…

**Microsoft’s Big Win in Quantum Computing Was an ‘Error’ After All**

The 2018 paper reported seeing telltale signatures of the Majorana particles, termed “zero-bias peaks,” in electric current passing through a tiny, supercold wire of semiconductor. An attached note from the authors said the original paper, in the prestigious journal Nature,…

**New research tackles a central challenge of powerful quantum computing**

” Explore further Error-protected quantum bits entangled for the first time More information: Jeffrey M. Gertler et al, Protecting a bosonic qubit with autonomous quantum error correction, Nature (2021). To build a universal quantum computer from fragile quantum components, effective implementation…

**New twist on cuprates could offer topological superconductivity at higher temperatures**

“Research at SBQMI seeks to unravel and exploit the complex phenomena that emerge in novel engineered materials, including topological states,” said Dr. Andrea Damascelli, Scientific Director at SBQMI. Franz and colleagues predict that their copper-based material will offer more flexibility…

**A rebel physicist has an elegant solution to a quantum mystery**

But, if they can, it will transform the way researchers approach reconciling special relativity’s big brother, general relativity, with quantum mechanics. 🔊 Listen to The WIRED Podcast, the week in science, technology and culture, delivered every Friday 👉 Follow WIRED…

**Full stack ahead: Pioneering quantum hardware allows for controlling up to thousands of qubits at cryogenic temperatures**

nest-like tangle of cables, which could work for limited numbers of qubits (and, perhaps, even at an “intermediate scale”) but not for large-scale quantum computers. Figure 3: Diagram of the digital logic block (inset…
