Researchers from Austria have developed a quantum protocol that allows them to rewind and manipulate the 'age' of particles at the quantum level, effectively controlling time within quantum systems. Using a device called a quantum switch, they demonstrated the ability to reverse the state of photons without prior knowledge of their history, which could enhance quantum computing and deepen our understanding of time and gravity. While not enabling actual time travel, this breakthrough offers promising technological applications in quantum information processing.
Scientists have discovered a method to manipulate the flow of time within quantum systems, allowing them to speed up, slow down, or reverse quantum states, which could enhance quantum computing capabilities, though it doesn't enable actual time travel for humans.

Physicists have experimentally confirmed the existence of 'time mirrors,' devices that can reverse wave signals in time using engineered metamaterials, marking a significant breakthrough in wave manipulation and opening new possibilities for communication, imaging, and understanding time in physics.
Scientists have discovered evidence of a material-based measure of the ability to reverse time, challenging the linear nature of time in certain materials like glass. This breakthrough in measuring time, known as material time, has been achieved through the study of glass's molecular reconfiguration, providing insight into its ability to reverse time on a molecular level. This finding could have significant implications for understanding the aging process of materials and the laws of physics.
Scientists at the City University of New York have created a "mirror" that can reflect an electromagnetic wave backward in time, paving the way for ultra-fast communication and computing applications using light. The mirror temporally reverses waves, reflecting them stretched out and reversed. The team's next endeavor will be to experiment in the hundreds of GHz, but they will still be far from the 400THz frequencies of visible light.
