Finite Imaginary-Time Evolution for Polynomial Unconstrained Binary Optimization
Jaehee Kim, Juhyeon Kim, Gwonhak Lee +4
Imaginary-time evolution is a standard primitive for ground-state preparation but is nonunitary, precluding direct quantum implementation. We develop Finite Imaginary-Time Evolutio…

Quantum Circuit Representation of Combinatorial Matrix Functions
Minhyeok Kang, Gwonhak Lee, Youngrong Lim +1
Permanents, hafnians, and loop-hafnians are combinatorial matrix functions closely related to perfect matchings in graphs. These matrix functions arise in the quantum amplitudes of…
