Quantum technology relies on qubits, the fundamental units of quantum computers, whose operation is influenced by quantum coherence time. Scientists believe that moiré excitons — electron-hole pairs trapped in overlapping moiré interference fringes — could serve as qubits in future nano-semiconductors. However, previous limitations in focusing light have caused optical interference, making it difficult to measure these excitons accurately.

Kyoto University researchers have developed a new technique to reduce moiré excitons, allowing for accurate measurement of quantum coherence time. Their findings, published in Nature Communications, reveal that the quantum coherence of a single moiré exciton remains stable for over 12 picoseconds at −269°C, significantly longer than that of excitons in traditional two-dimensional semiconductors. The confined moiré excitons in interference fringes help maintain quantum coherence, advancing the potential of quantum technology.

“We combined electron beam microfabrication techniques with reactive ion etching. By utilizing Michelson interferometry on the emission signal from a single moiré exciton, we could directly measure its quantum coherence time,” said Kazunari Matsuda of KyotoU’s Institute Advanced Energy.

Future space missions could use quantum technology to track water on Earth, explore the composition of moons and other planets, or probe mysterious cosmic phenomena.

The sensational event triggered rare auroras on the Sun and lasted a mere two hours.

The two planets came as close as within a quarter-of-a-degree, or about 50% of the angular size of the lunar disk.

Lorenzo Di Cola also captured the conjunction over L’Aquila Italy. Both Jupiter and Mars were visible to the naked eye in the constellation Taurus during the cozy meet-up.

The photographer also took this amazing composition image made up of nine interval timer photos showing the two planets rising through the sky. Mars and Jupiter are visible in conjunction and if you look carefully you can even see some of Jupiter’s moons.

Crypto exchange Coinbase just announced that Hawaii residents can now use its platform to buy and sell digital assets.

In a statement, the largest US-based crypto exchange says its products and services are now available in The Aloha State after the Hawaii Department of Commerce and Consumer Affairs (DCCA) Division of Financial Institutions (DFI) made regulatory changes that provided clarity for cryptocurrency firms.

Made by Cresilon, Traumagel can stop bleeding from gunshot wounds and is being looked at for future uses by the Department of Defense.

The dosage of tyrosine supplements given in studies greatly varies, ranging from fixed amounts of 2–20 g to 25–150 mg/kg of body weight.

Speak with a healthcare provider to discuss the most appropriate dose for your health concerns.

Many foods contain tyrosine, making it relatively easy to meet the daily requirements. Meat and meat products are among the best dietary sources. For example, each 6-ounce (oz) cooked serving of chicken and steak provides 1,446 mg and 1,640 mg of tyrosine, respectively.

Shooting timelapse is a complex process that requires skill and patience, which an astrophotographer considers to be the most important thing for its creation.

Update 3:27 p.m. EDT: SpaceX launched the Transporter-11 mission and landed the first stage booster. Payload deployment is set to begin close to 4 p.m. EDT (2000 UTC).

SpaceX launched its Falcon 9 rocket from Vandenberg Space Force Base, sending dozens of spacecraft into orbit with its latest rideshare mission launching from California. The rocket’s first stage booster touched down back near the launch site following stage separation, creating a sonic boom for those nearby.
