Block encoding of semiseparable matrices via their generators

Giacomo Antonioli, Gianna M. Del Corso, Roel Van Beeumen

We present an explicit quantum circuit that constructs a block encoding of a generator-representable semiseparable (one-pair) matrix directly from its two generators. For an $N\tim…

Efficient Calculation of Equilibrium Correlation Functions

Yizhi Shen, Roel Van Beeumen, Wibe A. de Jong +1

A majority of measurable dynamic quantities of a physical system is described as an equilibrium correlation function of the form $G_{A B} (t - t^{'}) = ⟨ A (t) B (t^{'}) ⟩$ , where $t^{'}$ …
