The Constant Geometric Speed Schedule for Adiabatic State Preparation
Mancheon Han, Hyowon Park, Sangkook Choi
The efficiency of adiabatic quantum evolution is governed by the evolution time , which typically scales as with the minimum energy gap . However, the r…
Fermionic-Adapted Shadow Tomography for dynamical correlation functions
Taehee Ko, Mancheon Han, Hyowon Park +1
Dynamical correlation functions are essential for characterizing the response of the quantum many-body systems to the external perturbation. As their calculation is classically int…
Classical optimization algorithms for diagonalizing quantum Hamiltonians
Taehee Ko, Sangkook Choi, Hyowon Park +1
Diagonalizing a Hamiltonian, which is essential for simulating its long-time dynamics, is a key primitive in quantum computing and has been proven to yield a quantum advantage for…
Quantum random power method for ground state computation
Taehee Ko, Hyowon Park, Sangkook Choi
We present a quantum-classical hybrid random power method that approximates a ground state of a Hamiltonian. The quantum part of our method computes a fixed number of elements of a…
