Quantum-accelerated imaging of N stars

چکیده
Imaging point sources with low angular separation near or below the Rayleigh criterion is important in astronomy, e.g., search for habitable exoplanets stars. However, measurement time required to resolve stars sub-Rayleigh region via traditional direct imaging usually prohibitive. Here we propose quantum-accelerated (QAI) significantly reduce using an information-theoretic approach. QAI achieves quantum acceleration by adaptively learning optimal measurements from data maximize Fisher information per detected photon. Our approach can be implemented experimentally linear-projection instruments followed a single-photon detector array. We estimate position, brightness and number of unknown $10\sim100$ times faster than same aperture. scalable large incoherent find widespread applicability beyond astronomy high-speed imaging, fluorescence microscopy efficient optical read-out qubits.

Accelerated Quantum Dynamics
ACCELERATED QUANTUM DYNAMICS by Morgan H. Lynch The University of Wisconsin-Milwaukee, 2017 Under the Supervision of Professor Valerică Raicu In this dissertation we develop a formalism for the computation of observables due to acceleration-induced particle physics processes. By using the spacetime structure produced by acceleration, we examine the properties of accelerated particle detectors a...
متن کاملQuantum imaging with N-photon states in position space.
We investigate the physics of quantum imaging with N > 2 entangled photons in position space. It is shown that, in paraxial approximation, the space-time propagation of the quantum state can be described by a generalized Huygens-Fresnel principle for the N-photon wave function. The formalism allows the initial conditions to be set on multiple reference planes, which is very convenient to descri...
متن کاملQuantum Radiation of Uniformly Accelerated Spherical Mirrors
We study quantum radiation generated by a uniformly accelerated motion of small spherical mirrors. To obtain Green’s function for a scalar massless field we use Wick’s rotation. In the Euclidean domain the problem is reduced to finding an electric potential in 4D flat space in the presence of a metallic toroidal boundary. The latter problem is solved by a separation of variables. After performi...
متن کاملQuantum stability of accelerated black holes.
We study quantum aspects of the accelerated black holes in some detail. Explicitly shown is the fact that a uniform acceleration stabilizes certain charged black holes against the well-known thermal evaporation. Furthermore, a close inspection of the geometry reveals that this is possible only for near-extremal black holes and that most nonextremal varieties continue to evaporate with a modifie...
