Researchers simulated how ultra-high laser pulses can generate a fourth beam of light from vacuum, confirming a long-predicted quantum effect called four-wave mixing, which could soon be tested with advanced laser facilities worldwide.
MIT researchers have achieved a breakthrough in quantum technologies by controlling quantum randomness using "vacuum fluctuations." This milestone opens up possibilities for probabilistic computing and ultra-precise field sensing. By injecting a weak laser "bias" into an optical parametric oscillator, the researchers were able to create controllable quantum randomness, allowing for the manipulation of probability distributions. This development has implications for simulating complex dynamics and optimizing systems that involve uncertainty and randomness.
