All realistic quantum systems interact with their environments and thereby must be considered as open quantum systems. When a quantum system is strongly coupled to its environment, the so-called ...

The Lieb-Schultz-Mattis (LSM) theorem is an important result in condensed matter physics. The LSM theorem states that a spin chain with half-integer spin and translation and rotation symmetry can not ...

Quantum systems tend to become less “quantum-y” as they interact with their environment. So when developing a mathematical description, it’s usually simpler just to view them as being closed off from ...

A research team has, for the first time in the world, elucidated the microscopic mechanism by which quantum order is lost and collapses in "open quantum environments" existing in nature. Since ...

What if time is not as fixed as we thought? Imagine that instead of flowing in one direction – from past to future – time could flow forward or backwards due to processes taking place at the quantum ...

Quantum computing has long been dominated by proprietary machines locked behind corporate and national lab firewalls, but a different model is starting to take shape. A growing coalition of ...

A growing number of quantum engineers worldwide have been trying to realize large-scale quantum networks, which consist of ...

Quantum mechanics is a physics framework that describes how matter and energy behave at an extremely small scale, ...

Integrating quantum computers into U.S. world-class supercomputers is now a strategic imperative for U.S. technological leadership in the next era of computing. Hybrid systems will synergize classical ...
