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.

Researchers at the University of Massachusetts Amherst along with collaborators from the University of Chicago have modified a microwave circulator to be used in quantum computing.
QuEra Computing, a global leader in neutral-atom quantum computing technology, today announced it has been awarded a 6.5 Billion JPY contract (approx. $41 M USD) by Japan’s National Institute of Advanced Industrial Science and Technology (AIST) to deliver a state-of-the-art quantum computer, advancing quantum capabilities in Japan.
A recent study published in Axioms delves into the double-step shape invariance of radial Jacobi-Reference (JRef) potential, revealing violations of conventional supersymmetric (SUSY) quantum mechanics rules. By dissecting the Darboux transformations, researchers elucidate the anomaly, shedding light on the breakdown of SUSY principles in specific quantum mechanical scenarios, offering insights into the broader landscape of quantum mechanics.

A group of researchers, from the University of California, Irvine Department of Physics and Astronomy used computer simulations to show that features observed in real galaxies are difficult to explain without dark matter, supporting the existence of dark matter as the leading model to describe the universe. The group published their findings in the Monthly Notices of the Royal Astronomical Society.
