Algorithms and numerical analysis in quantum computing
Abstract/Contents
- Abstract
- This dissertation delves into multiple facets of quantum computing and quantum algorithms from the perspective of an applied mathematician or numerical analyst and is segmented into four parts: 1. Efficient and Robust Quantum Phase Estimation (QPE) Algorithms: The first part presents a suite of efficient and robust QPE algorithms, tailored for early fault-tolerant quantum devices in the sense that they (1) use a minimal number of ancilla qubits, (2) allow for inexact initial states with a significant residual, (3) achieve the Heisenberg limit for the total resource used, and (4) have a diminishing prefactor for the maximum circuit length when the residual approaches zero. 2. Advanced Hamiltonian Learning Techniques: The second part discusses two efficient algorithms that deal with the Hamiltonian learning problem for many-body Fermionic and Bosonic systems. 3. Block-encoding of Pseudo-Differential Operators: In the third chapter, the focus shifts to the development of novel algorithms for the encoding of pseudo-differential operators, enhancing the quantum computing toolkit with more explicit and effective block-encoding strategies. 4. Optimization algorithms for Variational Quantum Circuits: Concluding the dissertation, a reinforcement learning-based algorithm is presented, offering new avenues for solving the difficult optimization problem of variational circuits.
