Ever since superconductivity was discovered in the early 1900s, it has both captivated and mystified scientists. Superconductors conduct electricity with virtually zero resistance, allowing for highly efficient transmission of electrical currents.
A group of researchers from the 5th Institute of Physics at the University of Stuttgart is making significant strides in the fields of quantum simulation and quantum computing based on Rydberg atoms.
A group of scientists from NASA and JAXA examined the massive black hole in the center of galaxy NGC 4151 using XRISM (X-Ray Imaging and Spectroscopy Mission).
Researchers employed a long-baseline quantum sensor network to search for dark photons, a potential candidate for dark matter. By correlating data from 15 atomic magnetometers over a distance of 1700 km, they achieved unprecedented sensitivity, constraining the parameter space for dark photon interactions and advancing terrestrial dark matter searches.

Scientists from the University of Basel and the NCCR SPIN have achieved the first controllable interaction between two-hole spin qubits in a typical silicon transistor.
A recent publication in the journal Physical Review Letters unveiled that researchers at the Sanford Underground Research Facility, a Department of Energy Office of Science user facility, conducted a search for dark matter particles using a highly sensitive detector deployed deep underground. Despite their efforts, no signal indicating the presence of dark matter was detected.
Quantum physics is challenging basic concepts about how materials behave. One of these concepts is that, unlike transparent glass or plastic, metals cannot conduct light in their interiors.
Researchers investigated the physicochemical properties of cadmium telluride/glutathione (CdTe/glutathione) quantum dots (QDs) synthesized via microwave irradiation for biomarker and monoclonal antibody testing.

Recent research published in Physical Review Letters, by researchers at the University of Portsmouth, revealed a quantum sensing system that reaches the highest level of quantum sensitivity in measuring the transverse displacement between two interfering photons.
Researchers from the University of Portsmouth have unveiled a quantum sensing scheme that achieves the pinnacle of quantum sensitivity in measuring the transverse displacement between two interfering photons.
Astronomers from NASA’s Goddard Space Flight Center uncovered massive, circular radio structures known as ORCs encircling galaxies. X-Ray observations indicate that the Cloverleaf ORC originated from the collision of two galaxy groups, with shockwaves generated by the collision giving rise to radio emissions.
This study delves into the phenomenon of dissipation-induced photon blockade within the anti-Jaynes–Cummings (anti-JC) model, offering insights into its potential for generating single-photon sources with high purity and average photon number.
