In classical physics, memory is defined in a straightforward way. If a system’s future behavior depends only on its current condition, it is considered memoryless. If earlier states continue to ...

An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings ...

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 ...

Attempts to understand quantum phase transitions in open systems usually rely on real‑time Lindbladian evolution, which tracks how a quantum state changes as it relaxes toward a steady state. This ...

Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information ...

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 ...

Researchers have achieved a breakthrough towards building scalable quantum computers. The team used cryoelectronics ...

Protons, the positively charged particles that help build every atom in our bodies, are starting to look less like classical billiard balls and more like quantum actors. A growing body of research now ...

Nvidia claims to have kicked off the “quantum-GPU computing era,” unveiling a way for quantum computers to interconnect with classical systems. Revealed at the chip giant’s GTC event in Washington, ...
