Over the past decades, quantum scientists have introduced various technologies that operate leveraging quantum mechanical effects, including quantum sensors, computers and memory devices. Most of ...

Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum ...

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) ...

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

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 ...

Quantum teleportation has moved from science fiction into laboratory reality, but not in the way popular culture imagines. Instead of beaming people or objects across space, physicists are learning ...

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side effect of quantum entanglement. A new study challenges the traditional idea ...

New advances in entanglement witnesses allow researchers to verify genuine multipartite entanglement even in noisy, high‑dimensional and computationally relevant quantum states Quantum entanglement ...

With billions invested and prototypes being tested outside the lab, the quantum era is starting to take shape. The unveiling by IBM of two new quantum supercomputers and Denmark’s plans to develop ...

The unveiling by IBM of two new quantum supercomputers and Denmark’s plans to develop “the world’s most powerful commercial quantum computer” mark just two of the latest developments in quantum ...
