Less precise but less noisy: local circuits for momentum-space state preparation and measurement
Etienne Granet, Henrik Dreyer
Quantum algorithms are usually optimized for gate count or circuit depth. We find on Quantinuum System Model H2 quantum computer that for a tight-binding chain ground state prepara…
Backpropagating Pauli Propagation
Sheng-Hsuan Lin, Etienne Granet, Kevin Hémery +1
We develop a backpropagation algorithm for evaluating parameter gradients in quantum circuits using Pauli propagation simulation. The method has computational complexity comparable…
Dynamical structure factor with a pumping approach on a trapped-ion quantum computer
Etienne Granet, Keisuke Murota, Henrik Dreyer +3
Dynamical structure factors (DSF) measured with neutron-scattering experiments provide key insights into the structure of materials. Their computation requires both the preparation…
Quantum trajectory simulation of two-dimensional non-equilibrium steady states with a trapped ion quantum processor
Anna Dalmasso, Arash Jafarizadeh, Julian Boesl +8
Digital quantum computers offer a promising route for studying complex many-body systems that are otherwise inaccessible by their classical counterparts. Capabilities including mid…
Spectral functions on a quantum computer through system-environment interaction
Etienne Granet, Ramil Nigmatullin, David T. Stephen +1
Spectral functions measured with angle-resolved photoemission spectroscopy (ARPES) provide key insight to elucidate the band structure of materials. Comparison with theory requires…
Observation of genuine D string dynamics in a U lattice gauge theory with a tunable plaquette term on a trapped-ion quantum computer
Rohan Joshi, Yizhuo Tian, Kevin Hemery +5
Quantum simulations of high-energy physics in D can probe dynamical phenomena nonexistent in one spatial dimension and access regimes that are challenging for existing classic…
Universal Gates from Braiding and Fusing Anyons on Quantum Hardware
Chiu Fan Bowen Lo, Anasuya Lyons, Dan Gresh +8
Topological quantum computation encodes quantum information in the internal fusion space of non-Abelian anyonic quasiparticles, whose braiding implements logical gates. This goes b…
