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…
Researchers attain coherent control of a hybrid quantum network node
A hybrid multiqubit node-based diamond color centers in a large-scale quantum network. Credit: Chang et al. Quantum technologies, which operate leveraging quantum mechanical phenomena, have the potential to outperform their…
It’s a quantum zoo out there, and scientists just found a dozen new ‘species’
A “map” of the zoo: quantum states emerging in samples of twisted molybdenum ditelluride. The peaks correspond to different fractional charges. Credit: Columbia University There are a seemingly endless number…
Matter mediates ultrastrong coupling between light particles
