In this article we discuss the physical principles behind new quantum devices and materials that require some form of nanoscale fabrication. The two systems we discuss are superconducting quantum circuits and nanomechanical resonators. Both systems involve many-body systems of a special kind in which particular collective degrees of freedom can be factored out of the microscopic dynamics and subject to quantum control. We discuss applications to precision metrology.

Quantum image transmission based on linear elements
Modeling of image transmission with a classic quantum computer interpreter is suggested. The transmission algorithm from the paper (Lemos G.B., et.al. Quantum Imaging with Undetected Photons, Nature,
Highly efficient cooling of mechanical resonator with square pulse drives.
TLDR
A study of optomechanical cooling under the drive of square pulses without smooth profile is presented, showing how to choose the amplitudes and durations ofsquare pulses, as well as the intervals between them, so that a mechanical resonator can be quickly cooled down to its ground state.
Synchronization in coupled mechanical resonator arrays
Opto-mechanical systems are based on the nonlinear coupling between the electromagnetic field in a resonator and an array of bulk mechanical resonators such that the frequency of the electromagnetic
Phase and amplitude dynamics of nonlinearly coupled oscillators.
TLDR
This paper addresses the amplitude and phase dynamics of a large system of nonlinearly coupled, non-identical damped harmonic oscillators, and shows that in the synchronised state the system has a regular structure related to the distribution of the frequencies of the individual oscillators.
Optimize cooling-by-measurement by reinforcement learning
Cooling by the conditional measurement demonstrates a transparent advantage over that by the unconditional counterpart on the average-population-reduction rate. This advantage, however, is blemished
Misinformation Regarding 5G and COVID-19 and the Psychological Mechanism Behind Them
In late 2019, the COVID-19 pandemic started to spread around the world (Fauci, Lane, & Redfield, 2020). Along with the virus, misinformation about the pandemic started to spread as well. Rumors

TLDR
A number of examples of research programs that could deliver quantum technologies in coming decades including: quantum information technology, quantum electromechanical systems, coherent quantum electronics, quantum optics and coherent matter technology are discussed.
Entangling a nanomechanical resonator and a superconducting microwave cavity
We propose a scheme able to entangle at the steady state a nanomechanical resonator with a microwave cavity mode of a driven superconducting coplanar waveguide. The nanomechanical resonator is
Cavity quantum electrodynamics for superconducting electrical circuits: An architecture for quantum computation
We propose a realizable architecture using one-dimensional transmission line resonators to reach the strong-coupling limit of cavity quantum electrodynamics in superconducting electrical circuits.
Optically induced entanglement of excitons in a single quantum Dot
TLDR
The result presents a first step toward the optical realization of quantum logic operations using two or more quantum dots by identifying the spectrum of the phase-sensitive homodyne-detected coherent nonlinear optical response in a single gallium arsenide quantum dot.
Strong coupling of a single photon to a superconducting qubit using circuit quantum electrodynamics
TLDR
It is shown that the strong coupling regime can be attained in a solid-state system, and the concept of circuit quantum electrodynamics opens many new possibilities for studying the strong interaction of light and matter.
Quantum theory of cavity-assisted sideband cooling of mechanical motion.
TLDR
It is found that reaching the quantum limit of arbitrarily small phonon numbers requires going into the good-cavity (resolved phonon sideband) regime where the cavity linewidth is much smaller than the mechanical frequency and the corresponding cavity detuning.
Prospects for cooling nanomechanical motion by coupling to a superconducting microwave resonator
