A new study suggests that aliens might be aware that humans lack the necessary quantum technology to detect them, which could explain why decades of searching have failed to uncover signs of intelligent extraterrestrial life. Theoretical physicist Latham Boyle proposes that advanced alien civilizations may use quantum communication methods, making them too sophisticated for us to perceive using conventional technology. “The concept of interstellar quantum communication is crucial because it broadens our understanding of how communication could occur across vast distances in space,” Boyle explains. If quantum communication exists, it could revolutionize human technology. However, scientists currently lack the equipment to detect such signals. Classical communication relies on electromagnetic waves to transmit messages over long distances. In contrast, quantum mechanics involves probabilistic methods and the behavior of particles, which could allow for the transmission and teleportation of information between light waves. Experiments have demonstrated that light waves can maintain their quantum states over large distances, making interstellar quantum networks theoretically possible. Boyle studied how aliens might use the quantum properties of light by comparing the information capacity and error rates of both classical and quantum communication. While a standard radio signal requires only a few captured light waves to be received accurately, quantum communication demands the reception of many photons in their delicate quantum state to decode the message correctly. According to Boyle’s calculations, antennas would need to be over 100 kilometers (more than 60 miles) wide to generate quantum states with a reasonable chance of success, even when collecting signals from relatively close galactic neighbors. Smaller antennas could work, but they would need to be positioned above Earth’s atmosphere, such as on the moon, to gather enough photons. “Any civilization capable of quantum communication would likely have the technology to observe Earth and realize that we are currently incapable of detecting their signals, which is why they may not be attempting to contact us,” Boyle concludes.
