A quantum internet is the holy grail of quantum information processing, enabling the
deployment of a broad range of quantum technologies and protocols on a global scale …

Quantum random sampling is the leading proposal for demonstrating a computational
advantage of quantum computers over classical computers. Recently the first large-scale …

A quantum computer attains computational advantage when outperforming the best
classical computers running the best-known algorithms on well-defined tasks. No photonic …

The preparation of long-range entangled states using unitary circuits is limited by Lieb-
Robinson bounds, but circuits with projective measurements and feedback (“adaptive …

Our world, of course, changed in many other ways as well since the publication of the first
edition. The global pandemic impacted all areas of society and will probably transform how …

Harnessing the full complexity of optical fields requires the complete control of all degrees of
freedom within a region of space and time—an open goal for present-day spatial light …

A critical challenge in develo** scalable quantum systems is correcting the accumulation
of errors while performing operations and measurements. It is known that systems where …

Quantum computing aims at exploiting quantum phenomena to efficiently perform
computations that are unfeasible even for the most powerful classical supercomputers …

Practical quantum networks require interfacing quantum memories with existing channels
and systems that operate in the telecom band. Here we demonstrate low-noise, bidirectional …

The ground state of the spin-1 Affleck, Kennedy, Lieb, and Tasaki (AKLT) model is a
