Qubitization of Arbitrary Basis Quantum Chemistry by Low Rank Factorization

2019 · arXiv (Cornell University)

Recent work has dramatically reduced the gate complexity required to quantum simulate chemistry by using linear combinations of unitaries based methods to exploit structure in the plane wave basis Coulomb operator. Here, we show that …

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, …
