During the last ten years, superconducting circuits have passed from being interesting
physical devices to becoming contenders for near-future useful and scalable quantum …

Quantum-classical hybrid algorithms are emerging as promising candidates for near-term
practical applications of quantum information processors in a wide variety of fields ranging …

Universal fault-tolerant quantum computers will require error-free execution of long
sequences of quantum gate operations, which is expected to involve millions of physical …

We propose a qubit efficient scheme to study ground-state properties of quantum many-body
systems on near-term noisy intermediate-scale quantum computers. One can obtain a tensor …

Enhancing optical nonlinearities so that they become appreciable on the single photon level
and lead to nonclassical light fields has been a central objective in quantum optics for many …

We use Pontryagin's minimum principle to optimize variational quantum algorithms. We
show that for a fixed computation time, the optimal evolution has a bang-bang (square …

We propose and analyze a deterministic protocol to generate two-dimensional photonic
cluster states using a single quantum emitter via time-delayed quantum feedback. As a …

The main objective of quantum simulation is an in-depth understanding of many-body
physics, which is important for fundamental issues (quantum phase transitions, transport,…) …

We present a comprehensive review on the state-of-the-art of the approximate analytic
approaches describing the finite-temperature thermodynamic quantities of the Lieb-Liniger …

We present a platform for the simulation of quantum magnetism with full control of
interactions between pairs of spins at arbitrary distances in 1D and 2D lattices. In our …
