his paper is addressed to possibility of implementation of quantum
computations by resonant excitation of target isotopologues in the gas
flow. Population of quantum states of selectively excited isotopologues can be
manipulated by the sequence of laser pulses. For optimal control of excitation
laser pulses should be specifically shaped. Moreover, their periodicity also
plays essential role. Supersonic overcooled gas flow is the best to use as
a quantum Turing machine, because molecular spectra are well resolved
and, therefore, better control over them by laser field can be implemented.
Decoherence level in ensemble of molecules and clusters, representing gas
flow, can be controlled by its rarefaction degree and extension. Evolution
of quantum states population is guided by the battery of femtosecond
lasers installed along the gas flow direction. Each laser emits laser pulse
of predesigned shape, which is related to some command written for the
quantum computer (unitary transformation). The quantum state in the end
of gas flow is the result of calculation. If gas flow transition time is not long
enough to complete all sequence of required commands, received final state
(intermediate solution) is recorded and translated into laser pulse shape,
assigned for initialization. Otherwise, initialization laser pulse is step-like with
intensity just high enough to excite all isotopologues to the same quantum
state. Final quantum state of the gas flow is read by the classical computer by
finalizing measurement, which is implemented as following: Once irradiated
gas flow feeds spectrometer, where electrons, corresponding to resulting
quantum state, are ejected by applied ionizing laser pulse. Obtained electron
energy spectra, bearing information of original optical spectrum, are recorded
by the network of surrounding electrodes, and then amplified. By analog-digital
convertor electrical currents induced on electrodes are transformed into digital
format for further processing on the classical computer.
Biography
Konstantin Lyakhov has completed his PhD in Theoretical
Physics in J W Goethe University in 2008. Since 2008, he has
been an Oil Reservoir Engineer in Petroleum Technologies. In
early 2010, he became a researcher in Institute of Biochemical
Physics of Russian Academy of Science. In late 2010, he
joined the Plasma Applications Laboratory, Nuclear and
Energy Engineering Department of Jeju National University,
as a researcher, and from 2012 as a Research Professor. He
has published 12 papers in SCI journals (in 10 of them as a first
author, total number of co-authors is no more than 2)
