The future development of quantum technologies relies on creating and manipulating
quantum systems of increasing complexity, with key applications in computation, simulation …

Quantum information technologies, on the one hand, and intelligent learning systems, on the
other, are both emergent technologies that are likely to have a transformative impact on our …

Gate set tomography (GST) is a protocol for detailed, predictive characterization of logic
operations (gates) on quantum computing processors. Early versions of GST emerged …

We propose a simple scheme to reduce readout errors in experiments on quantum systems
with finite number of measurement outcomes. Our method relies on performing classical …

Quantum measurements play a fundamental role in quantum mechanics. Especially,
generalized quantum measurements provide a powerful and versatile tool to extract …

We use quantum detector tomography to characterize the qubit readout in terms of
measurement positive operator-valued measures (POVMs) on IBM quantum computers IBM …

This review covers the latest developments in continuous-variable quantum-state
tomography of optical fields and photons, placing a special emphasis on its practical aspects …

Device-independent quantum key distribution (DIQKD) represents a relaxation of the
security assumptions made in usual quantum key distribution (QKD). As in usual QKD, the …

Quantum tomography is currently ubiquitous for testing any implementation of a quantum
information processing device. Various sophisticated procedures for state and process …

Measurement connects the world of quantum phenomena to the world of classical events. It
has both a passive role—in observing quantum systems—and an active one, in preparing …
