Quantum dynamics in open systems examines how quantum states evolve when coupled to an external environment. Unlike isolated systems, where unitary evolution preserves coherence, open systems ...

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 ...

OpenQSE is intended to address this fragmentation through an open, modular framework that allows different components of the quantum-HPC stack to interoperate. The longer-term goal is to make it ...

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 ...

The operation and performance of quantum computers relies on the ability to realize and control entanglement between multiple qubits. Yet entanglement between many qubits is inherently susceptible to ...

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 tiny machine made from just an atom and particles of light may sound impossibly simple, but it raises a surprisingly ...

Free-space quantum network milestone: Brookhaven National Laboratory and Stony Brook University transmitted entangled photons ...

It may sound surprising, but one of the most stubborn problems in building quantum ...
