Physicists developed simplified formulas to quantify quantum entanglement in strongly correlated electron systems. Their approach was applied to nanoscale materials, revealing unexpected quantum ...

The emergence of quantum entanglement is one of the fastest processes in nature. Scientists show that using special tricks, this can be investigated on an attosecond scale. Scientists have managed to ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

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

While quantum entanglement mimicks the first law of thermodynamics in terms of entropy in a system, scientists wonder if the second law—especially the part about reversibility—could hold true. A new ...

Ronald Hanson is at QuTech and the Kavli Institute of Nanoscience, Delft University of Technology, Delft 2628 CJ, the Netherlands. The authors show that for a 10-km fibre link, entanglement between ...

Nearly a century ago, the physicist Erwin Schrödinger called attention to a quirk of the quantum world that has fascinated and vexed researchers ever since. When quantum particles such as atoms ...

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 ...

Quantum entanglement — once dismissed by Albert Einstein as “spooky action at a distance” — has long captured the public imagination and puzzled even seasoned scientists. But for today’s quantum ...

Even if it is impossible to travel in time, there might be more hope for sending messages backwards, a new paper argues, ...
