Variational Quantum Annealing for Quantum Chemistry
Ka-Wa Yip, Kübra Yeter-Aydeniz, Sijia S. Dong
We introduce a variational quantum annealing (VarQA) algorithm for electronic structure theory, in which we use the quantum annealer as a sampler and prepare an ansatz state throug…
Analog classical simulation of closed quantum systems
Ka-Wa Yip
We develop an analog classical simulation algorithm of noiseless quantum dynamics. By formulating the Schrödinger equation into a linear system of real-valued ordinary differential…
Standard quantum annealing outperforms adiabatic reverse annealing with decoherence
Gianluca Passarelli, Ka-Wa Yip, Daniel A. Lidar +1
We study adiabatic reverse annealing (ARA) in an open system. In the closed system (unitary) setting, this annealing protocol allows avoidance of first-order quantum phase transiti…
Breakdown of the weak coupling limit in quantum annealing
Yuki Bando, Ka-Wa Yip, Huo Chen +2
Reverse annealing is a variant of quantum annealing, in which the system is prepared in a classical state, reverse-annealed to an inversion point, and then forward-annealed. We rep…
Suppression of crosstalk in superconducting qubits using dynamical decoupling
Vinay Tripathi, Huo Chen, Mostafa Khezri +3
Currently available superconducting quantum processors with interconnected transmon qubits are noisy and prone to various errors. The errors can be attributed to sources such as op…
Open-system modeling of quantum annealing: theory and applications
Ka Wa Yip
In this dissertation, we explore how quantum annealing (QA) and its applications behave in an open system setting. We give derivations and numerical recipes for effective parallel…
