摘要: Quantum field theory reconciles quantum mechanics and special relativity, and plays a central role in many areas of physics. We develop quantum algorithm to compute relativistic scattering probabilities massive quantum field with quartic self-interactions (φ^4 theory) spacetime four and fewer dimensions. Its run time is polynomial the number particles, their energy, desired precision, applies at both weak strong coupling. In strong-coupling high-precision regimes, our achieves exponential speedup over fastest known classical algorithm.
