Permutationally Invariant Quantum State Tomography for Fermions
Shion Yamashika, Daisuke Yamamoto
Quantum state tomography provides complete information about a quantum state, but its measurement cost generally grows exponentially with system size. In many-particle quantum simu…

Simulating Quantum Field Theories with Boundaries in Curved Spacetimes Using Open Spin Systems
Shunichiro Kinoshita, Keiju Murata, Daisuke Yamamoto +1
We develop a framework to simulate quantum field theories (QFTs) with boundaries in -dimenmsional curved spacetimes by employing open spin systems. Building upon our previou…
