Direct characterization of quantum dynamics with noisy ancilla
2015 · Physical Review A
We present methods for the direct characterization of quantum dynamics in which both the principal and ancilla systems undergo noisy processes. Using a concatenated error detection code, we discriminate between located and unlocated errors on …

Benchmarking Embedded Chain Breaking in Quantum Annealing
2021 · arXiv (Cornell University)
Quantum annealing solves combinatorial optimization problems by finding the energetic ground states of an embedded Hamiltonian. However, quantum annealing dynamics under the embedded Hamiltonian may violate the principles of adiabatic evolution and generate excitations that …

Prime factorization using quantum variational imaginary time evolution
2021 · Scientific Reports
The road to computing on quantum devices has been accelerated by the promises that come from using Shor's algorithm to reduce the complexity of prime factorization. However, this promise hast not yet been realized due …

Efficient Quantum Gate Discovery with Optimal Control
2021
Optimal control theory provides a framework for numerical discovery of device controls that implement quantum logic gates, but common objective functions used for optimization often assign arbitrarily high costs to otherwise useful controls. We propose …

Solving MaxCut with Quantum Imaginary Time Evolution
2022 · arXiv (Cornell University)
We introduce a method to solve the MaxCut problem efficiently based on quantum imaginary time evolution (QITE). We employ a linear Ansatz for unitary updates and an initial state involving no entanglement, as well as …

Graph decomposition techniques for solving combinatorial optimization problems with variational quantum algorithms
2023 · arXiv (Cornell University)
The quantum approximate optimization algorithm (QAOA) has the potential to approximately solve complex combinatorial optimization problems in polynomial time. However, current noisy quantum devices cannot solve large problems due to hardware constraints. In this work, …

Entanglement-Based Quantum Information Technology
2023 · arXiv (Cornell University)
Entanglement is a quintessential quantum mechanical phenomenon with no classical equivalent. First discussed by Einstein, Podolsky, and Rosen and formally introduced by Schrödinger in 1935, entanglement has grown from a scientific debate to a radically …

Computational Performance Bounds Prediction in Quantum Computing with Unstable Noise
2025 · arXiv (Cornell University)
Quantum computing has significantly advanced in recent years, boasting devices with hundreds of quantum bits (qubits), hinting at its potential quantum advantage over classical computing. Yet, noise in quantum devices poses significant barriers to realizing …
