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 ...

For years, progress in artificial intelligence has followed a simple rule: make it bigger with more layers, more connections, more computing power. However, a new study suggests otherwise. Instead of ...

Sitting in an office at QuEra Computing’s Boston headquarters, Yuval Boger was talking about the recent advancements made in quantum computing that are driving the chorus around an accelerated the ...

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 ...
