Quantum-enhanced spectroscopy with entangled multiphoton states

2016 · Physical Review A

Traditionally, spectroscopy is performed by examining the position of absorption lines. However, at frequencies near the transition frequency, additional information can be obtained from the phase shift. In this work we consider the information about …

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 …
