Quantum errors are a normal part of quantum computing because fragile physical qubits (the tiny components storing data) can easily break down because of environmental noise, like heat, stray signals or microscopic vibrations. ...
Today's quantum technologies rely on energy-intensive lasers, raising concerns that scaling them up could further increase energy demands. In new work, researchers have demonstrated that quantum entanglement between photons ...
In early 2025, special signals wended their way through a fiber-optic highway strung above the streets and sidewalks of the Maryland suburbs. The arrival of those signals at their destination marks a significant step toward ...
In mathematics and getting dressed, some processes are commutative, while others are noncommutative. Commutative means the order doesn't matter (3 + 2 is the same as 2 + 3, and it doesn't matter which sock goes on first). ...
Semiconductor spin qubits are one of the most promising building blocks for future quantum computers, but turning them into a working, large-scale quantum computer has so far proven difficult. For now, two big questions remain ...
For years, researchers have tried to harness the "twist" of light to transmit data. This property describes how light spirals as it travels forward, and because it can be molded into a virtually infinite number of different ...
Electrons zipping through transistors, powering the screens on our smartphones. Light zooming from distant stars to Earth, moving faster than anything else in the universe. Protons enabling MRI machines to analyze people's ...
Quantum technologies are devices and systems that exploit the laws of quantum mechanics and could perform tasks that are difficult or impossible to tackle using their classical counterparts. These technologies process and ...
The promise of quantum computing is to solve complex problems faster and more energy-efficiently than today's supercomputers—from optimizing logistics to simulating molecules. This goal is coming within reach as the number ...
Sending quantum information through a chain of qubits, like energy through a Newton's cradle, could be the key to faster operations and take quantum computing to the next level.
