Global optimization of quantum dynamics with AlphaZero deep exploration [PDF]
npj Quantum Information, 2019 While a large number of algorithms for optimizing quantum dynamics for different objectives have been developed, a common limitation is the reliance on good initial guesses, being either random or based on heuristics and intuitions.

Controlling quantum many-body dynamics in driven Rydberg atom arrays
Science, 2021 Dynamic stabilization of an array Large-scale systems comprising one-dimensional chains and two-dimensional arrays of excited atoms held in a programmable optical lattice are a powerful platform with which to simulate emergent phenomena. Bluvstein et al.

A possibilistic no-go theorem on the Wigner’s friend paradox
New Journal of Physics, 2023 The famous ‘Wigner’s friend’ paradox highlights the difficulty of modelling the evolution of quantum systems under measurement in situations where observers themselves are considered to be subject to the laws of quantum mechanics.

Observation of Critical Phenomena in Parity-Time-Symmetric Quantum Dynamics. [PDF]
Physical Review Letters, 2018 We experimentally simulate nonunitary quantum dynamics using a single-photon interferometric network and study the information flow between a parity-time- (PT-)symmetric non-Hermitian system and its environment.

Quantum Dynamics of a Few-Photon Parametric Oscillator [PDF]
Physical Review X, 2019 Modulating the frequency of a harmonic oscillator at nearly twice its natural frequency leads to amplification and self-oscillation. Above the oscillation threshold, the field settles into a coherent oscillating state with a well-defined phase of either $

Experimental noiseless linear amplification using weak measurements
New Journal of Physics, 2016 The viability of quantum communication schemes rely on sending quantum states of light over long distances. However, transmission loss can degrade the signal strength, adding noise.

Proposal for demonstration of long-range cluster state entanglement in the presence of photon loss
APL Photonics, 2017 Photonic cluster states are a crucial resource for optical quantum computing. Recently a quantum dot single photon source has been demonstrated to produce strings of single photons in a small linear cluster state.

On the power of one pure steered state for EPR-steering with a pair of qubits
New Journal of Physics, 2023 As originally introduced, the Einstein, Podolsky and Rosen (EPR) phenomenon was the ability of one party (Alice) to steer, by her choice between two measurement settings, the quantum system of another party (Bob) into two distinct ensembles of pure ...

The simplest demonstrations of quantum nonlocality
New Journal of Physics, 2012 We investigate the complexity cost of demonstrating the key types of nonclassical correlations—Bell inequality violation, Einstein, Podolsky, Rosen (EPR)-steering, and entanglement—with independent agents, theoretically and in a photonic experiment.

New Journal of Physics, 2022 The image-charge detection provides a new direct method for the detection of the Rydberg transition of electrons trapped on the surface of liquid helium. The interest in this method is motivated by the possibility to accomplish the spin state readout for
