quantum computing

For the first time, a quantum computer has been operated in space, marking a milestone in the effort to take quantum computing beyond Earth. Scientists say the demonstration opens the path to space-based quantum processing, which could eventually support secure communications and Earth observation. The achievement is drawing wide attention as a proof of concept for future quantum technologies in orbit.

UCLA has received $75 million in grants from the National Science Foundation to advance quantum technology research. The funding will support the university's work in quantum science, a field seen as key to future computing, sensing and communications. The announcement highlights growing federal investment in quantum research at American universities.

Researchers have used a quantum computer to simulate particles of matter effectively popping into existence, reproducing a phenomenon predicted by quantum field theory. The experiment demonstrates how quantum machines can model processes that are extremely difficult for classical computers, offering a new way to study the fundamental behavior of the universe. Physicists see it as a step toward simulating complex particle interactions directly.

Researchers report that a quantum memory has stored single photons for a record length of time, a result being described as a major step toward building a quantum internet. Such memories are needed to link quantum computers and send unbreakable encrypted signals over long distances, since quantum information is normally lost within fractions of a second. The record storage time suggests networking quantum devices is becoming technically feasible.

Researchers report the first direct observation of a single phonon—the smallest possible unit of sound—disappearing, according to a new physics study. The feat means measuring sound at its most fundamental quantum level, in a single isolated unit, rather than in waves made of countless phonons. Scientists say the result opens a window onto how quantum behaviour works in mechanical systems, with potential implications for quantum computing and sensing technologies.

Dow, S&P 500 and Nasdaq futures climbed as investors weighed hopes for diplomatic progress on Iran alongside continued strength in artificial intelligence stocks. Quantum computing firm IonQ, biotech Voyager Therapeutics (VKTX) and Broadcom-related names were among the stocks drawing attention as markets opened the week on a cautiously optimistic note.

India's Defence Research and Development Organisation, working with a startup, has built a 20 millikelvin refrigerator, the extreme cooling unit required to operate quantum computers. Such dilution refrigerators bring quantum processors to temperatures near absolute zero and have previously been dominated by a handful of foreign suppliers, making the development a step toward domestic quantum computing capability.
