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 a larger…

Theoretically calculated (left) and experimentally observed (right) spectroscopic signals in proposed method. Credit: Peter Yun An atomic clock research team from the National Time Service Center of the Chinese Academy…
The first experimental observation of Dirac exceptional points
Dirac exceptional point. The figure illustrates that the Dirac exceptional point exhibits both a real-valued energy spectrum in its vicinity and eigenstate degeneracy. Credit: Wu et al Exceptional points (EPs)…
New physics theory to study low-energy excitations in quantum quasicrystals
By developing a microscopic quantum elasticity theory, this work describes the dynamics of deformations in a quasicrystalline lattice of bosonic particles at the lowest temperatures. Figure (a) illustrates an example…
New quantum optics theory proposes that classical interference arises from bright and dark states of light
Double slit interference. Photons arrive everywhere on the screen, but in the bright/dark regions in a bright/dark quantum state, respectively, that can/cannot excite the atom which is used to monitor…
To Understand a Special Hadron, Researchers Turn to Supercomputers and Quantum Chromodynamics
The Science Newswise — Hadrons are particles formed by quarks and gluons that are bound together by the strong nuclear force. Nuclear scientists need to understand how hadrons behave and interact with other…
Search for Sterile Neutrinos Continues at Nuclear Reactors
Newswise — Neutrinos, elusive fundamental particles, can act as a window into the center of a nuclear reactor, the interior of the earth, or some of the most dynamic objects…
Quantum sensors tested for next-generation particle physics experiments
The SMSPDs can precisely detect single particles at a time. The detectors were designed and fabricated at JPL and commissioned at the INQNET-Caltech labs. Credit: Cristián Peña, Fermilab To learn…
