Introduction to quantum noise, measurement, and amplification
The topic of quantum noise has become extremely timely due to the rise of quantum information physics and the resulting interchange of ideas between the condensed matter and atomic, molecular,
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.
Cooling a nanomechanical resonator with quantum back-action
TLDR
The back-action of a superconducting single-electron transistor (SSET) on a radio-frequency nanomechanical resonator is measured to anticipate the use of these back- action effects to prepare ultracold and quantum states of mechanical structures, which would not be accessible with existing technology.
Dispersive optomechanics: a membrane inside a cavity
We present the results of theoretical and experimental studies of dispersively coupled (or 'membrane in the middle') optomechanical systems. We calculate the linear optical properties of a high
Nonreciprocal Photon Transmission and Amplification via Reservoir Engineering
We discuss a general method for constructing nonreciprocal, cavity-based photonic devices, based on matching a given coherent interaction with its corresponding dissipative counterpart; our method
Using interference for high fidelity quantum state transfer in optomechanics.
TLDR
It is shown that this system possesses an effective mechanically dark mode which is immune to mechanical dissipation; utilizing this feature allows highly efficient transfer of intracavity states, as well as of itinerant photon states.
Preparation and detection of a mechanical resonator near the ground state of motion
TLDR
This work reports the cooling of the motion of a radio-frequency nanomechanical resonator by parametric coupling to a driven, microwave-frequency superconducting resonator, and expects the mechanical resonator to be found with probability 0.21 in the quantum ground state of motion.
Arbitrarily large steady-state bosonic squeezing via dissipation
We discuss how large amounts of steady-state quantum squeezing (beyond 3 dB) of a mechanical resonator can be obtained by driving an optomechanical cavity with two control lasers with differing
Speeding up Adiabatic Quantum State Transfer by Using Dressed States.
TLDR
New pulse schemes to significantly speed up adiabatic state transfer protocols are developed and it is shown that a suitable choice of dressed states allows one to design fast protocols that do not require additional couplings, while simultaneously minimizing the occupancy of the "intermediate" level.
Topological Quantum Fluctuations and Traveling Wave Amplifiers
It is now well-established that photonic systems can exhibit topological energy bands; similar to their electronic counterparts, this leads to the formation of chiral edge modes which can be used to
