Superconducting diode bridge efficiently converts AC to DC for quantum circuits
Superconductivity is an advantageous property observed in some materials, which entails an electrical resistance of zero at extremely low temperatures. Superconductors, materials that exhibit this property, have proved to be highly promising for the development of...
A new method to control the rovibrational ground state of a single molecular hydrogen ion
The precise measurement of states in atomic and molecular systems can help to validate fundamental physics theories and their predictions. Among the various platforms that can help to validate theoretical predictions are so-called diatomic molecular hydrogen ions...
Quantum simulator realizes strongly interacting Mott-Meissner phases in bosonic flux ladders
When exposed to periodic driving, which is the time-dependent manipulation of a system's parameters, quantum systems can exhibit interesting new phases of matter that are not present in time-independent (i.e., static) conditions. Among other things, periodic driving...
Using a fermionic neural network to find the ground state of fractional quantum Hall liquids
When two-dimensional electron systems are subjected to magnetic fields at low temperatures, they can exhibit interesting states of matter, such as fractional quantum Hall liquids. These are exotic states of matter characterized by fractionalized excitations and the...
Two distinct exciton states observed in 2H stacked bilayer molybdenum diselenide
Two-dimensional (2D) materials have proved to be a promising platform for studying exotic quasiparticles, such as excitons. Excitons are bound states that emerge when an electron in a material absorbs energy and rises to a higher energy level, leaving a hole (i.e.,...

A scalable approach to distill quantum features from higher-dimensional entanglement
The operation of quantum technologies relies on the reliable realization and control of quantum states, particularly entanglement. In the context of quantum physics, entanglement entails a connection between particles, whereby measuring one determines the result of...
New microwave-to-optical transducer uses rare-earth ions for efficient quantum signal conversion
Quantum technologies, which leverage quantum mechanical effects to process information, could outperform their classical counterparts in some complex and advanced tasks. The development and real-world deployment of these technologies partly relies on the ability to...
Study shows that duality operators can be realized as unitary linear-depth quantum circuits
In the context of quantum physics, the term "duality" refers to transformations that link apparently distinct physical theories, often unveiling hidden symmetries. Some recent studies have been aimed at understanding and implementing duality transformations, as this...
