Measurement-based simulation of lattice gauge theory dynamics with adaptive quantum circuits on a trapped-ion processor
Hiroki Sukeno, Enrico Rinaldi, Takuya Okuda
Measurement-based quantum simulation (MBQS)---a recently proposed architecture for simulating lattice gauge theories---implements Hamiltonian dynamics by consuming a model-specific…
Anomaly inflow for CSS and fractonic lattice models and dualities via cluster state measurement
Takuya Okuda, Aswin Parayil Mana, Hiroki Sukeno
Calderbank-Shor-Steane (CSS) codes are a class of quantum error correction codes that contains the toric code and fracton models. A procedure called foliation defines a cluster sta…
Quantum gate broadcasting on graphs
Hiroki Sukeno, Tzu-Chieh Wei
Given a known or unknown phase encoded in a higher-dimensional qudit gate, it is possible to send copies of a gate that encodes the phase to multiple receivers based on a generaliz…
Bulk and boundary entanglement transitions in the projective gauge-Higgs model
Hiroki Sukeno, Kazuki Ikeda, Tzu-Chieh Wei
In quantum many-body spin systems, the interplay between the entangling effect of multi-qubit Pauli measurements and the disentangling effect of single-qubit Pauli measurements may…
Feedback-based Quantum Algorithm Inspired by Counterdiabatic Driving
Rajesh K. Malla, Hiroki Sukeno, Hongye Yu +3
In recent quantum algorithmic developments, a feedback-based approach has shown promise for preparing quantum many-body system ground states and solving combinatorial optimization…
Improved Quantum Power Method and Numerical Integration Using Quantum Singular Value Transformation
Nhat A. Nghiem, Hiroki Sukeno, Shuyu Zhang +1
Quantum singular value transformation (QSVT) is a framework that has been shown to unify many primitives in quantum algorithms. In this work, we leverage the QSVT framework in two…
