Scientists have developed a quantum chip that converts uncontrolled photon leaks into controllable signals. The approach enables tracking of lost quantum information through deliberate controlled leakage.
A new quantum chip has been created to address challenges in managing photon leaks during experiments. It transforms messy leaks into signals that researchers can control and monitor effectively.
Researchers at EPFL have created the first chip-scale ultrafast laser that matches the performance of traditional tabletop femtosecond lasers. The device delivers pulses as short as 147 femtoseconds with energies of 1.05 nanojoules.

Researchers from Kyoto University and Hiroshima University have created a new technique to identify W states, a complex form of quantum entanglement. The advance could support progress in quantum computing and communication.
Researchers at Los Alamos National Laboratory have developed a method to effectively reverse time in quantum systems, enabling energy harvesting for potential use in quantum batteries. The technique counteracts the effects of measurements on qubits, making systems appear to run backwards. This could turn measurements into a thermodynamic resource.
