For the first time, researchers have demonstrated that the properties of the perovskite family of materials can be used to create so-called quantum bits. The findings, published in the journal Nature Communications, pave the way for more affordable materials in future quantum computers. Go to Source The controlled generation of single photons is an essential element of numerous quantum technology applications, such as quantum networks and quantum computing. A research team has now demonstrated the successful application of the new SUPER (Swing-UP of the quantum EmitteR population) method. The approach facilitates the controlled generation of light particles (photons). Results of the […] Superconducting materials could play a crucial role in the energy-efficient applications of the future. However, several technical challenges still stand in the way of their practical use. Now, researchers at Chalmers University of Technology in Sweden have developed a new material design that addresses a major obstacle in the field: enabling superconductivity to operate at […] The bizarre properties of discrete time crystals could be harnessed to detect extremely subtle oscillations of magnetic fields, physicists in the US and Germany have revealed. Publishing their results in Nature Physics, a team led by Ashok Ajoy at the University of California, Berkeley, show for the first time that these exotic materials could have […] Researchers from Tokyo Metropolitan University have succeeded in detecting laser-assisted electron scattering (LAES) using circularly polarized light for the first time. The use of circularly polarized light promises valuable insights into how atomic scale “helicity” impacts how electrons interact with matter and light. Go to Source Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for precision measurement, found in optical clocks, gas-sensing spectrometers, and instruments that detect the light signatures of exoplanets. Traditionally, frequency combs are produced by large, fiber-laser systems ranging from the size of a shoebox to a refrigerator. Go to Source […] Research is actively underway to develop a “dream memory” that can reduce heat generation in smartphones and laptops while delivering faster performance and lower power consumption. Korean researchers propose a new possibility for controlling magnetism using the exchange interaction of electron orbitals—the motion of electrons orbiting around an atomic nucleus—rather than relying on the conventional […] Electrons are tiny and constantly in motion. How they behave in a crystal lattice determines key material properties: electrical conductivity, magnetism, or novel quantum effects. Anyone aiming to develop the information technologies of tomorrow must understand what electrons do. At Forschungszentrum Jülich, a new tool is now available for this purpose: a momentum microscope that […] Researchers from the Texas Center for Superconductivity (TcSUH) and the department of physics at the University of Houston have broken the temperature record for superconductivity at ambient pressure—a breakthrough that could eventually lead to more efficient ways to generate, transmit, and store energy. Go to Source Neutrinos are extremely lightweight and electrically neutral particles that rarely interact with ordinary matter. Due to these rare interactions, neutrinos can travel across space almost entirely unaffected, carrying information about highly energetic cosmological events, such as exploding stars or supermassive black holes. Go to Source Cerebral blood flow is essential for normal brain function and often perturbed in neurological disease. If one shines a source of coherent light on perfused tissue, the detected speckles, or “grains” of light fluctuate, or “dance,” at a rate proportional to blood flow in the volume sampled by the light. In brain tissue, this concept […] Multiferroic metals are materials that exhibit both electric polarization and magnetic order in the same crystal—a state known as multiferroicity. Because these properties coexist, they can interact through magnetoelectric (ME) coupling, allowing electric fields to influence magnetism. Go to Source Fleeting electron-hole pairs are giving scientists a new window into optimizing light-emitting devices (LEDs). Using quantum magnetic resonance, Osaka Metropolitan University researchers have discovered how shifting internal electric fields dictate whether these devices shine brightly or dimly. Their study is published in the journal Advanced Optical Materials. Go to Source Although the potential applications of quantum computing are widespread, a new feasibility study suggests quantum computers still face major hurdles in solving quantum chemistry problems. The study, published in Physical Review B, evaluates what criteria are needed for a quantum advantage in searching for the ground state energy of molecules. The researchers attempt this feat […] For the first time, researchers in China have demonstrated how quantum dots can be engineered to consistently generate pairs of entangled photons. By carefully tailoring the photonic environment surrounding a single quantum dot, the team showed that it is possible to produce highly correlated photon pairs with remarkable efficiency, potentially opening new opportunities for emerging […] |
