DESCRIPTION:Title: Analog emulators of quantum systems\nby E.Halubek\, K.Pomorski
(Quantum Hardware Systems) as part of Workshop on Quantum Hardware-Softwa
re Systems\n\n\nAbstract\nThe model presented by Gabriel Kron in 1945 is a
n example of an analog computer simulating quantum phenomena on a hardware
level. It uses passive RLC elements to construct a hardware solver for th
e problem of quantum particles confined by rectangular or other classes of
potential. The analytical and numerical validation of Kron’s second mod
el is conducted for different shapes of particle-confining potentials in t
he one-dimensional case using an LTspice simulator. Thus\, there remains p
otential for obtaining solutions in two- and three-dimensional cases. Here
\, a circuit model representing a linearized Ginzburg–Landau equation is
given. Kron’s second model is generalized by the introduction of linear
and non-linear resistive elements. This transforms the deformed Schrödin
ger equation into a linear dissipative Schrödinger equation and its non-l
inear form. The quantum mechanical roton problem is the main result of thi
s work and is formulated by means of classical physical states naturally p
resent in the LC classical circular electrical transmission line. The expe
rimental verification of Kron’s model is confirmed.\n\nhttps://us06web.z

DESCRIPTION:Title: Electrostatically Interacting Wannier Qubits in Curved Space (II)<
/a>\nby Krzysztof Pomorski (Quantum Hardware Systems) as part of Workshop
on Quantum Hardware-Software Systems\n\n\nAbstract\nA derivation of a tigh
t-binding model from Schrödinger formalism for various topologies of posi
tion-based semiconductor qubits is presented in the case of static and tim
e-dependent electric fields. The simplistic tight-binding model enables th
e description of single-electron devices at a large integration scale. The
case of two electrostatically Wannier qubits (also known as position-base
d qubits) in a Schrödinger model is presented with omission of spin degre
es of freedom. The concept of programmable quantum matter can be implement
ed in the chain of coupled semiconductor quantum dots. Highly integrated a
nd developed cryogenic CMOS nanostructures can be mapped to coupled quantu
m dots\, the connectivity of which can be controlled by a voltage applied
across the transistor gates as well as using an external magnetic field. U
sing the anti-correlation principle arising from the Coulomb repulsion int
eraction between electrons\, one can implement classical and quantum inver
ters (Classical/Quantum Swap Gate) and many other logical gates. The anti-
correlation will be weakened due to the fact that the quantumness of the p
hysical process brings about the coexistence of correlation and anti-corre
lation at the same time. One of the central results presented in this work
relies on the appearance of dissipation-like processes and effective pote
ntial renormalization building effective barriers in both semiconductors a
nd in superconductors between not bended nanowire regions both in classica
l and in quantum regimes. The presence of non-straight wire regions is als
o expressed by the geometrical dissipative quantum Aharonov–Bohm effect
in superconductors/semiconductors when one obtains a complex value vector
potential-like field. The existence of a Coulomb interaction provides a ba
se for the physical description of an electrostatic Q-Swap gate with any t
opology using open-loop nanowires\, with programmable functionality. We ob
serve strong localization of the wavepacket due to nanowire bending. There
fore\, it is not always necessary to build a barrier between two nanowires
to obtain two quantum dot systems. On the other hand\, the results can be
mapped to the problem of an electron in curved space\, so they can be exp
ressed with a programmable position-dependent metric embedded in Schrödin
ger’s equation. The semiconductor quantum dot system is capable of mimic
king curved space\, providing a bridge between fundamental and applied sci
ence in the implementation of single-electron devices.\n\nhttps://us06web.
