Quantum information systems derive their power from controllable interactions that generate quantum entanglement. Buiding scalable quantum information systems require programmable operations between desired qubits within a quantum processor. In most advanced approaches, qubits interact locally, constrained by the connectivity associated with their fixed spatial layout. In a new study, scientists demonstrated a quantum processor in…
40 Eri B is the second brightest white dwarf and among the first to be discovered in 1783. White dwarfs were once normal stars similar to the Sun but collapsed after exhausting all their fuel. Since the discovery of the first white dwarf, astronomers have tried to gain more insights into white dwarfs to get…
Antiferromagnetic insulators are advantageous in spintronic applications because of their low stray fields and rapid magnetic dynamics. Controlling their magnetization and reading their magnetic state is critical for these applications, but they are challenging. Scientists at Northwestern University have discovered a new quantum phenomenon in antiferromagnetic insulators. This phenomenon could yield new ways of powering…
American astronomer Edwin Hubble and others discovered in the 1920s that the Universe is expanding by showing that most galaxies are receding from the Milky Way — and the farther away they are, the faster they are receding. The Hubble constant is a unit that describes how fast the Universe is expanding at different distances…
Combining artificial intelligence with many keen human eyes, astronomers have found 1701 new asteroid trails in archival data from the NASA/ESA Hubble Space Telescope, consisting of more than 37 000 images that span two decades. The project reflects both Hubble’s value to scientists as an asteroid hunter and how the public can effectively contribute to…
The polariton is a quasiparticle formed by the strong coupling to a matter excitation. It is a crucial ingredient of emergent photonic quantum systems ranging from semiconductor nanophotonics to circuit quantum electrodynamics. Using the interaction between polaritons has led to the realization of superfluids of light and strongly correlated phases in the microwave domain, with…
Before about 3.8 billion years ago, Mars may have had a denser atmosphere and higher surface temperatures. But today, the current Martian atmosphere is too thin and cold to support liquid water. Plus, the atmospheric pressure is less than one percent of the pressure of Earth’s atmosphere. How did Mars go from a state potentially…
UNSW scientists have announced a breakthrough in the field of renewable energy. They have developed a new kind of solar cells that can produce electricity even at night.’ Known as ‘Night-time’ solar power, the technology generates electricity from heat radiated as infrared light, in the same way as the Earth cools by radiating into space…
When we have something, the essential nutrients and other valuable components within the food are metabolized and find their way to cells throughout the body. When the metabolites reach the cell, they are completely broken down and segregated from one another so that each can play a role in specific functions that the mitochondria perform.…
Saturn has 82 moons. They range in size from larger than the planet Mercury. Recently, NASA took Twitter to share an image of Saturn’s Moon Mimas, captured by the Cassini spacecraft. Discovered on Sept. 17, 1789, by English astronomer William Herschel, using his 40-foot reflector telescope, Mimas is the smallest and innermost of Saturn’s major…
