Quantum technologies exploit entanglement to revolutionize computing, measurements, and
communications. This has stimulated the research in different areas of physics to engineer …

This study presents a survey on quantum control theory and applications from a control
systems perspective. Some of the basic concepts and main developments (including open …

The ability to accurately control the dynamics of physical systems by measurement and
feedback is a pillar of modern engineering. Today, the increasing demand for applied …

This paper provides an introduction to quantum filtering theory. An introduction to quantum
probability theory is given, focusing on the spectral theorem and the conditional expectation …

Quantum information describes the new field which bridges quantum physics and
information science. The quantum world allows for completely new architectures and …

We develop generalized bounds for quantum single-parameter estimation problems for
which the coupling to the parameter is described by intrinsic multisystem interactions. For a …

Quantum sensing is one of the arenas that exemplifies the superiority of quantum
technologies over their classical counterparts. Such superiority, however, can be diminished …

We describe an alkali-metal magnetometer for detection of weak magnetic fields in the radio-
frequency (rf) range. High sensitivity is achieved by tuning the Zeeman resonance of alkali …

Feedback control of quantum mechanical systems must take into account the probabilistic
nature of quantum measurement. We formulate quantum feedback control as a problem of …

Real-time feedback performed during a quantum nondemolition measurement of atomic
spin-angular momentum allowed us to influence the quantum statistics of the measurement …
