In recent years, many physicists and computer scientists have been working on the development of quantum computing technologies. These technologies are based on qubits, the basic units of quantum information.

Study demonstrates a new method to search for meV dark photons
Approximately 85% of the mass of our galaxy is comprised by dark matter, matter that does not emit, absorb or reflect light and thus cannot be directly observed. While several studies have hinted at or theorized about its composition, it remains one of the greatest...
Researchers derive a unified topological speed limit for the evolution of physical states
Physical systems evolve at a particular speed, which depends on various factors including the system's so-called topological structure (i.e., spatial properties that are preserved over time despite any physical changes that occur). Existing methods for determining the...
The Floquet engineering of quantum materials
Quantum materials are materials with unique electronic, magnetic or optical properties, which are underpinned by the behavior of electrons at a quantum mechanical level. Studies have showed that interactions between these materials and strong laser fields can elicit...
The first experimental bosonic stimulation of atom-light scattering in an ultracold gas
Bosons, one of the two fundamental classes of particles, have been the focus of countless physics studies. When bosonic particles are transitioning into an already occupied final quantum state, the rate of this transition is enhanced by its so-called "occupation...
Study observes Luttinger liquid behavior in a quasi-2D system
Luttinger liquids are usually paramagnetic materials exhibiting non-Fermi liquid behavior, such as molybdenum oxides. These "liquids" and their fascinating properties had so far been only observed in 1D and quasi-1D compounds, such as blue...
Study uncovers existing limitations in the detection of entanglement
Quantum entanglement is a process through which two particles become entangled and remain connected over time, even when separated by large distances. Detecting this phenomenon is of crucial importance for both the development of quantum technology and the study of...
Study observes spin-orbit-parity coupled superconductivity in thin 2M-WS2
In recent years, many physicists and material scientists have been studying superconductors, materials that can conduct direct current electricity without energy loss when cooled under a particular temperature. These materials could have numerous valuable...
Could axion decay underlie excess cosmic optical background?
The cosmic optical background (COB) is the visible light emitted by all sources outside of the Milky Way. This faint glow of light, which can only be observed using very precise and sophisticated telescopes, could help astrophysics to learn more about the origins of...
A numerical protocol to estimate local entropy production
In physics, equilibrium is a state in which a system's motion and internal energy do not change over time. Videos of systems in equilibrium would look exactly the same if they were watched in their normal chronological progression or backwards. This symmetry means...
