Sine-Gordon Model with Bosonic Tensor Networks: Continuum Matching and Soliton Scattering
Florian Hechenberger, Tommaso Rainaldi, Felix Ringer
We use bosonic tensor networks to connect the lattice sine-Gordon model in the Hamiltonian formulation quantitatively to its continuum theory. Matching the lattice vertex operator…
Trigonometric Continuous-Variable Quantum Gates: Realization with Trapped Ions and Nonperturbative Wigner Negativity
Tommaso Rainaldi, Jake Montgomery, Christopher G. Yale +8
We experimentally realize trigonometric continuous-variable gates on a trapped-ion processor, for which a motional mode acquires a phase proportional to the cosine of its position…
Encoding Compact U(1) Gauge Fields in Bosonic Modes with GKP Stabilization
Victor Ale, Tommaso Rainaldi, Enrique Rico +2
Compact lattice gauge theories are formulated in terms of angular variables and integer electric fluxes, while bosonic quantum hardware provides oscillator modes with continuous, u…
Trigonometric continuous-variable gates and hybrid quantum simulations of the sine-Gordon model
Tommaso Rainaldi, Victor Ale, Matt Grau +5
Hybrid qubit-qumode quantum computing platforms provide a natural setting for simulating interacting bosonic quantum field theories. However, existing continuous-variable gate cons…
Simulating quantum electrodynamics in 2+1 dimensions with qubits and qumodes
Victor Ale, Tommaso Rainaldi, Enrique Rico +2
We develop a hybrid qubit-qumode framework for simulating quantum electrodynamics in 2+1 dimensions. In this approach, fermionic matter fields are represented by qubits, while U(1)…
