Quantum control is concerned with active manipulation of physical and chemical processes
on the atomic and molecular scale. This work presents a perspective of progress in the field …

It is control that turns scientific knowledge into useful technology: in physics and engineering
it provides a systematic way for driving a dynamical system from a given initial state into a …

The idea of the out-of-time-order correlator (OTOC) has recently emerged in the study of
both condensed matter systems and gravitational systems. It not only plays a key role in …

A central challenge in quantum computing is to identify more computational problems for
which utilization of quantum resources can offer significant speedup. Here, we propose a …

Because of its geometric nature, holonomic quantum computation is fault tolerant against
certain types of control errors. Although proposed more than a decade ago, the experimental …

Processing of digital images is continuously gaining in volume and relevance, with
concomitant demands on data storage, transmission, and processing power. Encoding the …

Robust measurement of single quantum bits plays a key role in the realization of quantum
computation and communication as well as in quantum metrology and sensing. We have …

Quantum computers [1–4] are explicitly quantum mechanical systems that use phenomena
such as superposition and entanglement to perform computational tasks more efficiently …

A pivotal task in quantum metrology, and quantum parameter estimation in general, is to
design schemes that achieve the highest precision with the given resources. Standard …
