The purpose of this tutorial is to give a brief introduction to linear quantum control systems.
The mathematical model of linear quantum control systems is presented first, then some …

The interaction between photons and a single two-level atom constitutes a fundamental
paradigm in quantum physics. The nonlinearity provided by the atom leads to a strong …

The interaction of a single photon with an individual two-level system is the textbook
example of quantum electrodynamics. Achieving strong coupling in this system has so far …

Flying qubit is one type of the basic elements for transmitting quantum information in
quantum networks. It can serve as a communication link between quantum computer nodes …

The control of flying quantum bits (qubits) carried by traveling quantum fields is crucial for
coherent information transmission in quantum networks. In this paper, we develop a general …

The control of flying qubits is at the core of quantum networks. When the flying qubits are
carried by single-photon fields, the control involves not only their logical states but also their …

We present precise, subwavelength optical intensity measurements using a single trapped
Rb 87 atom as a sensor. The intensity is measured by the scalar ac Stark shift it produces on …

We present a method to produce pure single photons with an arbitrary designed temporal
shape in a heralded way. As an indispensable resource, the method uses pairs of time …

We study the generation of single-photon pulses with the tailored temporal shape via
nonlocal spectral filtering. A shaped photon is heralded from a time-energy entangled …

Loading quantum information deterministically onto a quantum node is an important step
toward a quantum network. Here, we demonstrate that coherent-state microwave photons …
