Researchers from EPFL and IBM have developed a groundbreaking photonic-chip-based traveling-wave parametric amplifier (TWPA) that offers ultra-broadband optical signal amplification in a compact form. Using gallium phosphide-on-silicon dioxide technology, the amplifier delivers over 10 dB gain across 140 nm—three times the bandwidth of conventional EDFAs. Its strong optical nonlinearity boosts signals efficiently while minimizing noise. This innovation enhances optical networks, AI data centers, and precision sensing applications, marking a major step forward in high-speed data transmission and next-generation photonics.

Breakthrough in Quantum Phase Transitions Advances Quantum Technologies
EPFL Researchers Observe First- and Second-Order Dissipative Phase Transitions
EPFL researchers have experimentally observed both first- and second-order dissipative phase transitions (DPTs) in a superconducting Kerr resonator. By introducing a two-photon drive, they precisely controlled quantum state transitions, revealing phenomena like squeezing, hysteresis, and critical slowing down. Their findings confirm theoretical predictions and enhance understanding of quantum systems. This breakthrough could lead to improved quantum computing error correction and ultra-sensitive quantum sensors. The study highlights the power of interdisciplinary collaboration, merging experimental physics, theory, and engineering to push the boundaries of quantum science.
Study uncovered earliest evidence transport technology used by ancient settlers
Drag marks reveal how our ancestors moved heavy loads.
Researchers from Bournemouth University discovered early evidence of transport technology used by settlers in the USA over 20,000 years ago at White Sands National Park, New Mexico. They found drag marks from makeshift vehicles called “travois,” made from wooden poles, alongside ancient human footprints. The tracks included single lines, likely from dragging two poles joined at one end, and parallel lines, from poles crossed in the middle.
The quantum processor that redefines computing speed
It is one quadrillion faster than the fastest supercomputer.
Researchers from the University of Science and Technology of China (USTC) have created a superconducting quantum computing prototype called Zuchongzhi-3. This prototype operates with 105 qubits and 182 couplers, making it 1015 times faster than the fastest supercomputer and one million times faster than Google's latest results. This breakthrough marks a significant advancement in quantum computing performance.
