Reinforcement learning of quantum circuit architectures for molecular potential energy curves

Maureen Krumtünger, Alissa Wilms, Paul K. Faehrmann +4

Quantum chemistry and optimization are two of the most prominent applications of quantum computers. Variational quantum algorithms have been proposed for solving problems in these…

Stability of digital and analog quantum simulations under noise

Jayant Rao, Jens Eisert, Tommaso Guaita

Quantum simulation is a central application of near-term quantum devices, pursued in both analog and digital architectures. A key challenge for both paradigms is the effect of impe…

No Universal Purification in Quantum Mechanics

Zhenhuan Liu, Zhenyu Du, Jens Eisert +2

Many central tasks in fundamental physics and quantum information processing are possible only insofar as mixed quantum states can be made purer. In this work, we prove that the li…

Energy-independent tomography of Gaussian states

Lennart Bittel, Francesco A. Mele, Jens Eisert +1

The exploration of tomography of bosonic Gaussian states is presumably as old as quantum optics, but only recently, their precise and rigorous study have been moving into the focus…

Quantum circuit simulation with a local time-dependent variational principle

Aaron Sander, Maximilian Fröhlich, Mazen Ali +6

Classical simulations of quantum circuits are vital for assessing potential quantum advantage and benchmarking devices, yet they require sophisticated methods to avoid the exponent…

Classical simulation of noisy quantum circuits via locally entanglement-optimal unravelings

Simon Cichy, Paul K. Faehrmann, Lennart Bittel +2

Classical simulations of noisy quantum circuits are instrumental to our understanding of the behavior of real-world quantum systems and the identification of regimes where one expe…
