Enhanced SAR Image Processing Using A Heterogeneous Multiprocessor
Author(s) :
SHI, YU
Description :
Synthetic antenna aperture (SAR) is a pulses focusing airborne radar which can achieve high resolution radar image. A number of image process algorithms have been developed for this kind of radar, but the calculation burden is still heavy. So the image processing of SAR is normally performed “off-li...

High Energy Quantum Teleportation Using Neutral Koans
Author(s) :
Shi, Yu
Description :
We describe a scheme of stochastic implementations of quantum teleportation
and entanglement swapping in terms of neutral kaons. In this scheme, the kaon
whose state is to be teleported collides with one of the two entangled kaons in
an Einstein-Podolsky-Rosen state. Subsequent detection of the ou...

Spontaneous Symmetry Breaking, Off-diagonal Long-range Order, and Nucleation of Quantum State
Author(s) :
Shi, Yu
Description :
Spontaneous symmetry breaking originats in quantum mechanical measurement of
the relevant observable defining the physical situation, order parameter is the
average of this observable. A modification is made on the random-phase
postulate validating the ensemble description. Off-diagonal long-range...

Non-partial Reality
Author(s) :
Shi, Yu
Description :
Study on pre- and postselected quantum system indicates that ``product rule''
and ``sum rule'' for elements of reality should be abandoned. We show that this
so-called non-partial realism can refute arguments against hidden variables in
a unified way, and might save local realism.

Early Gedanken Experiments of Quantum Mechanics Revisited
Author(s) :
Shi, Yu
Description :
The famous gedanken experiments of quantum mechanics have played crucial
roles in developing the Copenhagen interpretation. They are studied here from
the perspective of standard quantum mechanics, with no ontological
interpretation involved. Bohr's investigation of these gedanken experiments,
bas...

Remarks on Universal Quantum Computer
Author(s) :
Shi, Yu
Description :
According to Deutsch, a universal quantum Turing machine (UQTM) is able to
perform, in repeating a fixed unitary transformation on the total system, an
arbitrary unitary transformation on an arbitrary data state, by including a
program as another part of the input state. We note that if such a UQT...

Entanglement Between Bose-Einstein Condensates
Author(s) :
Shi, Yu
Description :
For a Bose condensate in a double-well potential or with two
Josephson-coupled internal states, the condensate wavefunction is a
superposition. Here we consider coupling two such Bose condensates, and suggest
the existence of a joint condensate wavefunction, which is in general a
superposition of ...

Scalings of Pitches in Music
Author(s) :
Shi, Yu
Description :
We investigate correlations among pitches in several songs and pieces of
piano music by mapping them to one-dimensional walks. Two kinds of correlations
are studied, one is related to the real values of frequencies while they are
treated only as different symbols for another. Long-range power law ...
