"Breakthrough in Quantum Sensors Enables Data Collection from the Past"

Researchers at Washington University in St. Louis, along with collaborators from NIST and the University of Cambridge, have developed a quantum sensor leveraging quantum entanglement that could potentially collect data from the past. This breakthrough, detailed in a study published in Physical Review Letters, involves a two-qubit superconducting quantum processor and demonstrates a quantum advantage that could enable temporally manipulated measurements, marking a significant step toward practical time-travel technology.
