A brief account of the quantum information dynamics and dynamical programming methods for optimal control of quantum unstable systems is given to both open loop and feedback control schemes corresponding respectively to deterministic and stochastic semi-Markov dynamics of stable or unstable systems. For the quantum feedback control scheme, we exploit the separation theorem of filtering and cont...

The high-rise steel structure building (structure) is a relatively special structure. Due to its high height characteristics and the overall narrowness, there still no unified method for this type of demolition. This paper aimed at studying simulation demolition structures by blasting through computer video images. For reason, proposes specific work based on LS-DYNA software. Through an update ...

The contemporary landscape is rife with ruins, from circumscribed tourist attractions to urban decay and demolition sites. When examined, our aesthetic experience of these sites ranges from historical distancing to the sublime and, when found in our local communities (e.g., Providence, RI), to discomfort, displacement, and horror. In particular, this paper is interested in how certain forms of ...

Electromagnetically induced transparency (EIT) has been often proposed for generating nonlinear optical effects at the single photon level; in particular, as a means to effect a quantum non-demolition measurement of a single photon field. Previous treatments have usually considered homogeneously broadened samples, but realisations in any medium will have to contend with inhomogeneous broadening...

We propose to measure the quantum state of a single mode of the radiation field in a cavity— the signal field—by coupling it via a quantum-non-demolition Hamiltonian to a meter field in a highly squeezed state. We show that quantum state tomography on the meter field using balanced homodyne detection provides full information about the signal state. We discuss the influence of measurement of th...

Quantum teleportation is a transport of quantum state of a system to another similar system via a classical channel [1]. The principles of quantum mechanics demand that for realization of such a transport, the sender and the receiver must have two ancillary quantum systems, being strongly quantum-mechanically correlated (entangled). Quantum teleportation is a fundamental phenomenon of quantum w...
