Noise structuring in fixed-depth Trotter simulation: stationary channels and observable-level depolarization
G. L. Stavisskii, W. V. Pogosov, L. E. Fedichkin +1
We analyze fixed-depth Trotter simulation as a method for structuring hardware noise in digital many-body dynamics. The number of layers is chosen using the largest endpoint time a…
Energy-selective quantum search with Ising Hamiltonian phase oracles
A. S. Plyashechnik, A. A. Zhukov, A. V. Lebedev +1
Ising Hamiltonians are basic models of disordered magnets and a standard language for quantum and classical optimization. We study an energy-selective quantum search primitive in w…
Time-adaptive phase estimation
Brennan de Neeve, Andrey V. Lebedev, Vlad Negnevitsky +1
Phase estimation is known to be a robust method for single-qubit gate calibration in quantum computers, while Bayesian estimation is widely used in devising optimal methods for lea…
Grover's search meets Ising models: a quantum algorithm for finding low-energy states
Andrey Zhukov, Andrey Lebedev, Walter Pogosov
We propose a methodology for implementing Grover's algorithm in the digital quantum simulation of disordered Ising models. The core concept revolves around using the evolution oper…
