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 ...

Stable control and manipulation are critical for quantum technology and require a deep understanding of the underlying interactions of physical platforms with their surroundings. Open system theory ...

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 ...

Sound waves, light waves and other types of waves, generally spread freely through space and over time. In 1958, physicist ...

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 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 ...

Interdisciplinary teams across the Quantum Systems Accelerator (QSA) are using innovative approaches to push the boundaries of superconducting qubit technology, bridging the gap between today's NISQ ...

Fault-tolerant quantum computer by 2028: the DOE’s Quantum Genesis initiative sets a hard deadline for the world’s first ...

A quantum system built from just nine atoms has outperformed classical artificial intelligence models containing thousands of processing nodes in multi-day weather forecasting, delivering prediction ...

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 ...
