Phys.org on MSN: Do decoherence, gravity, dark matter and dark energy all originate from quantum corrections?
Do decoherence, gravity, dark matter and dark energy all originate from quantum corrections?
A research team has identified environmental interactions as the cause of ultrafast electronic decoherence in solids, a long-standing open question in quantum physics. (Nanowerk News) A physics team ...
Physics World: When charging quantum batteries, decoherence is a friend, not a foe
The qubit state decays toward the “north pole” of the sphere due to decoherence. Using the study’s coherence-stabilized sensing protocol, the researchers temporarily counteracted the decay, leading to ...
Physicists Gimin Bae, Youngjae Kim, and Jae Dong Lee have identified a specific microscopic process that causes quantum coherence to collapse in solid-state materials, pinning the timescale of ...
techtimes: Breaking Barriers: How Quantum Coherence and XI Science Unlock Human Potential
In October 2024, researchers at the University of Science and Technology of China reached a new frontier in quantum physics: a Schrödinger-cat state with an unprecedented coherence time of 1,400 ...
Phys.org: Quantum coherence could be preserved at large scales in realistic environments
In physics, a quantum (pl.: quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. The fundamental notion that a property can be "quantized" is referred to as "the hypothesis of quantization ". [1] This means that the magnitude of the physical property can take on only discrete values consisting of integer multiples of one quantum. For example, a ...
Quantum, in physics, discrete natural unit, or packet, of energy, charge, angular momentum, or other physical property. Light, for example, appearing in some respects as a continuous electromagnetic wave, on the submicroscopic level is emitted and absorbed in discrete amounts, or quanta.
