By quantum confinement, I refer to the phenomenon where the energy of a quantum particle—like an electron—increases significantly when its motion is restricted in space.

Quantum chromodynamics (QCD) is the theoretical framework for studying the forces within atomic nuclei and their constituent protons and neutrons. A major part of QCD research involves how quarks ...

In quantum technologies, emitter coherence time is a critical bottleneck. Traditional subradiant states—long-lived entangled states in waveguide QED—suppress collective decay through ...

Flow of time at the quantum level. A graph based on the researchers' equations shows opposing arrows of time. Source: Thomas Guff et al./Scientific Reports (2025) ...

Researchers at the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, together with international ...

To understand confinement, let’s begin with some quantum basics. ... Over time, the increased entanglement of the system makes it hard for a classical computer to simulate.

Physicists have struggled to understand the nature of time since the field began. But a new theoretical study suggests time could be an illusion woven at the quantum level.

After forty years, the creator of quantum scar theory has observed the phenomenon in real time. Quantum scarring is a phenomenon in which traveling electrons end up following the same repeating path.

At the same time, quantum algorithms are improving far faster than hardware. A recent collaboration between the pharmaceutical giant Boehringer Ingelheim and PsiQuantum demonstrated a more than ...

It's about time . In quantum mechanics, our best theory of the microscopic world, time is a fixed phenomenon — an inexorable, unidirectional flow from the past to the present.It remains external ...
