A new study published in the British journal Nature reveals that a novel quantum sensor can eliminate the impact of background noise on measurement accuracy, enabling the search for faint signals that were previously difficult to detect with existing technology. This advancement may help unravel the mystery of supermassive black hole formation. According to a press release from Imperial College London, measuring extremely faint signals is crucial for understanding the composition of the universe and discovering new sources of gravitational waves. While atomic interferometers can utilize atomic matter-wave interference for measurements, noise from laser pulses may overwhelm the signals, resulting in the inability to obtain valid data.
