Measurement-induced entanglement and teleportation on a noisy quantum processor

2023 · arXiv (Cornell University)

Measurement has a special role in quantum theory: by collapsing the wavefunction it can enable phenomena such as teleportation and thereby alter the "arrow of time" that constrains unitary evolution. When integrated in many-body dynamics, …

Strategies for running the QAOA at hundreds of qubits

2024 · arXiv (Cornell University)

We explore strategies aimed at reducing the amount of computation, both quantum and classical, required to run the Quantum Approximate Optimization Algorithm (QAOA). First, following Wurtz et al. [Phys.Rev A 104:052419], we consider the standard …
