Real-time scattering processes with continuous-variable quantum computers (2025)
Journal Article
Abel, S., Spannowsky, M., & Williams, S. (2025). Real-time scattering processes with continuous-variable quantum computers. Physical Review A, 112(1), Article 012614. https://doi.org/10.1103/q36d-w649

We propose a framework for simulating the real-time dynamics of quantum field theories using continuous-variable quantum computing (CVQC). Focusing on (1+1)-dimensional 𝜑4 scalar field theory, the approach employs the Hamiltonian formalism to map the...
