Quantum entanglement is a process through which two particles become entangled and remain connected over time, even when separated by large distances. Detecting this phenomenon is of crucial importance for both the development of quantum technology and the study of...

Study observes spin-orbit-parity coupled superconductivity in thin 2M-WS2
In recent years, many physicists and material scientists have been studying superconductors, materials that can conduct direct current electricity without energy loss when cooled under a particular temperature. These materials could have numerous valuable...
The observation of an anomalous Hall effect in altermagnetic ruthenium dioxide
The Hall effect is a conduction phenomenon discovered by physicist Edwin Herbert Hall that describes the development of a transverse electric field in solid materials carrying electric current that are placed in a magnetic field perpendicular to this current. In the...
A scalable quantum memory with a lifetime over 2 seconds and integrated error detection
Quantum memory devices can store data as quantum states instead of binary states, as classical computer memories do. While some existing quantum memory technologies have achieved highly promising results, several challenges will need to be overcome before they can be...
Evidence of Higgs boson contributions to the production of Z boson pairs at high energies
The Higgs boson, the fundamental subatomic particle associated with the Higgs field, was first discovered in 2012 as part of the ATLAS and CMS experiments, both of which analyze data collected at CERN's Large Hadron Collider (LHC), the most powerful particle...
Recent searches for light fermionic dark matter by the PandaX-4T collaboration
Teams of astrophysicists worldwide are trying to observe different possible types of dark matter (DM), hypothetical matter in the universe that does not emit, absorb or reflect light and would thus be very difficult to detect. Fermionic DM, however, which would be...
The direct measurement of a proton’s generalized polarizabilities in the strong quantum chromodynamics regime
Quantum chromodynamics is an area of study that explores the strong interactions between quarks mediated by gluons. Quarks are elementary particles with an electric charge, which are building blocks of composite particles, such as hadrons and protons.
Study proves a generalization of Bell’s theorem: Quantum correlations are genuinely tripartite and nonlocal
Quantum theory predicts the existence of so-called tripartite-entangled states, in which three quantum particles are related in a way that has no counterpart in classical physics. Theoretical physicists would like to understand how well new theories, alternatives to...
Exploring the decay processes of a quantum state weakly coupled to a finite-size reservoir
In quantum physics, Fermi's golden rule, also known as the golden rule of time-dependent perturbation theory, is a formula that can be used to calculate the rate at which an initial quantum state transitions into a final state, which is composed of a continuum of...
The coherent simulation of a quantum phase transition in a programmable 2,000 qubit Ising chain
Quantum computers have the potential to outperform classical computers on several complex tasks, yet many challenges will need to be overcome before they reach their full potential. In the meantime, physicists and computer scientists have been trying to realistically...
