Quantum Observer.

Morals & Machines, 2022
In this paper we examine the representations of quantum theory and technology in visual media. Namely, we conduct a thorough content analysis of film scripts in science fiction and fantasy to discover ways quantum physics and computing are portrayed: examples include quantum computer scepticism, quantum as proxy for complexity/intelligence, and quantum

Observation of Quantum Jumps

Physical Review Letters, 1986
We have recorded the laser-excited resonance fluorescence of one to three ${\mathrm{Ba}}^{+}$ ions and observed Bohr's "quantum jumps" when an ion decayed to the metastable $^{2}D_{\frac{5}{2}}$ state, suddenly quenching its fluorescence. Most of the jumps mark Raman-Stokes scattering from the $^{2}S_{\frac{1}{2}}$ and $^{2}D_{\frac{3}{2}}$ levels.

Simultaneous observation of quantum contextuality and quantum nonlocality

Science Bulletin, 2018
Quantum nonlocality and quantum contextuality are the most curious properties that change our understanding of nature, and were observed independently in recent decades. One important question is whether both properties can be observed simultaneously. In this paper, we show that in a qutrit-qutrit system we can observe quantum nonlocality and quantum ...

Quantum observer for linear quantum stochastic systems

2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012
The purpose of this paper is to investigate the extension of the Luenberger observer design approach to linear quantum stochastic systems to obtain coherent quantum observers. We show how a physically realizable quantum observer can be designed, consistent with the laws of quantum mechanics. The quantum observer has the property that the mean values of

Relative randomness of quantum observables

Physical Review A, 1991
We investigate statistics of matrix elements of observables, calculated in an eigenbasis of a quantum-mechanical evolution operator corresponding to a classically chaotic system. We propose a criterion that allows one to predict whether or not such statistics are faithful to random-matrix theory and define a random operator with respect to a given ...
