New protocol counteracts the limitation of decoherence
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…

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…
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…
