Generation of entangled Schrödinger cat state of two macroscopic mirrors.
TLDR
It is shown that the high fidelity between the obtained state and the target state can be achieved in the presence of dissipation and thermal noise within the authors' parameter regions, which suggests that the state-generation proposal is feasible. Expand
SCHEME TO PROBE THE DECOHERENCE OF A MACROSCOPIC OBJECT
We propose a quantum optical version of Schrodinger's famous gedanken experiment in which the state of a microscopic system ~a cavity field! becomes entangled with and disentangled from the state ofExpand
Reservoir-engineered entanglement in optomechanical systems.
We show how strong steady-state entanglement can be achieved in a three-mode optomechanical system (or other parametrically coupled bosonic system) by effectively laser cooling a delocalizedExpand
Nonclassical-state generation in macroscopic systems via hybrid discrete-continuous quantum measurements
Nonclassical-state generation is an important component throughout experimental quantum science for quantum information applications and probing the fundamentals of physics. Here, we investigateExpand
Significant-Loophole-Free Test of Bell's Theorem with Entangled Photons.
TLDR
A Bell test is reported that closes the most significant of loopholes that provide loopholes for a local realist explanation of quantum mechanics, using a well-optimized source of entangled photons, rapid setting generation, and highly efficient superconducting detectors. Expand
A Schrödinger cat living in two boxes
TLDR
It is shown that the cat can be in two separate locations at the same time and the ability to manipulate such multicavity quantum states paves the way for logical operations between redundantly encoded qubits for fault-tolerant quantum computation and communication. Expand
Two-mode squeezed states in cavity optomechanics via engineering of a single reservoir
We study theoretically a three-mode optomechanical system where two mechanical oscillators are independently coupled to a single cavity mode. By optimized two-tone or four-tone driving of the cavityExpand
Ponderomotive control of quantum macroscopic coherence
It is shown that because of the radiation pressure a Schr\"odinger cat state can be generated in a resonator with an oscillating wall. The optomechanical control of quantum macroscopic coherence andExpand
Loophole-free Bell inequality violation using electron spins separated by 1.3 kilometres
TLDR
The data imply statistically significant rejection of the local-realist null hypothesis and could be used for testing less-conventional theories, and for implementing device-independent quantum-secure communication and randomness certification. Expand
Preparation of nonclassical states in cavities with a moving mirror
We describe how a quantum system composed of a cavity field interacting with a movable mirror can be utilized to generate a large variety of nonclassical states of both the cavity field and theExpand
