Quantum computers will need large numbers of qubits to tackle challenging problems in physics, chemistry, and beyond. Unlike classical bits, qubits can exist in two states at once—a phenomenon called superposition. This quirk of quantum […]

The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving some mathematical graffiti into Dublin’s Broome Bridge in 1843. Click to rate this post! [Total: […]
Researchers at the National University of Singapore (NUS) have observed a doping-tunable charge density wave (CDW) in a single-layer semiconductor, Chromium(III) selenide (Cr2Se3), extending the CDW phenomenon from metals to doped semiconductors. Click to rate […]
RIKEN physicists have found a way to speed up the readout of qubits in superconducting quantum computers, which should help to make them faster and more reliable. Click to rate this post! [Total: 0 Average: […]
Imagine the benefits if the entire internet got a game-changing upgrade to speed and security. This is the promise of the quantum internet—an advanced system that uses single photons to operate. Researchers at Tohoku University […]
When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, hides one of the oldest puzzles in physics: what really happens to the momentum of […]
In a study published in Reports on Progress in Physics, researchers have achieved device-independent characterization of genuinely entangled subspaces (GESs) in both optical and superconducting quantum systems, completing the self-checking of the five-qubit error correction […]
The quantum many body problem has been at the heart of much of theoretical and experimental physics over the past few decades. Even though we have understood the fundamental laws that govern the behavior of […]
Quantum technologies are systems that can compute data, sense their surrounding environment or perform other functions leveraging quantum mechanical effects. Connecting these technologies over long distances has so far proved challenging, as quantum information can […]
Nature has many rhythms: the seasons result from Earth’s movement around the sun, the ticking of a pendulum clock results from the oscillation of its pendulum. These phenomena can be understood with very simple equations. […]
