To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, ...

Efficient generation and reliable distribution of quantum entangled states is crucial for emerging quantum applications, including quantum key distribution (QKDs). However, conventional ...

But after reading Decoherence and Quantum Darwinism, a book published in March 2025 by the physicist Wojciech Zurek, I’m excited by the possibility of an answer that does away with all those fanciful ...

Adiabatic quantum computing An example problem represented by an energy landscape. Each point on the landscape represents a candidate solution. The deepest valley represents the actual solution with ...

Fig.1 Schematic of the experimental setup for continuous-variable entanglement-assisted quantum comumication.Alice encodes classical signals on the ancilla beam by an amplitude modulator (AM) and a ...

Saturday Night Fever: you may remember the dance performed by John Travolta and Karen-Lynn Gorney to the Bee Gees song (1) "More than a woman". The two dancers perform a perfectly prepared dance, ...

A hundred years ago this week, at the height of the quantum revolution, Austrian physicist Erwin Schrödinger submitted a manuscript for publication. Its centerpiece was an innocuous-looking equation ...

Researchers have demonstrated that quantum entanglement can link atoms across space to improve measurement accuracy. By splitting an entangled group of atoms into separate clouds, they were able to ...

How BTQ’s Bitcoin-like quantum testnet highlights where post-quantum risks may emerge and why mitigation is an engineering challenge. Bitcoin’s quantum risk centers on exposed public keys and ...

Researchers from the Faculty of Engineering at The University of Hong Kong (HKU) have made a significant discovery regarding quantum entanglement. This phenomenon, which has long been viewed as a ...
