Quantum control of acoustic waves
2023A key role in quantum communication technologies is the efficient transport of information between quantum resources (such as spins, superconducting circuits, or light). Typically, one would use microwaves, guided by microwave waveguides, as a transportation mechanism.

Physics of Plasmas, 2003
The one-dimensional two-species quantum hydrodynamic model is considered in the limit of small mass ratio of the charge carriers. Closure is obtained by adopting an equation of state pertaining to a zero-temperature Fermi gas for the electrons and by disregarding pressure effects for the ions.

Microwave Quantum Acoustic Processor
2019 IEEE MTT-S International Microwave Symposium (IMS), 2019We propose an architecture for microwave quantum information processing based on high-Q microwave mechanical resonators coupled to a superconducting qubit. Detailed calculations of the error budget show that there is a trade-off between cross-talk and amplitude damping that leads to an optimal value of g on the order of 10 MHz.

Pseudospin quantum acoustics in liquids
Ultrasonics, 1980Abstract We call attention to the fact that data on spin-lattice relaxation in liqudis can give information about the rate of resonant acoustic transitions in substances where ordinary electron paramagnetic resonance (epr) and nuclear magnetic resonance (nmr) have been studied.

So far all forms of acoustical imaging are diffraction limited and so their resolution limit obeys Rayleigh’s criterion, that is λ/2, where λ is the sound wavelength. In this paper, we apply quantum theory to acoustical imaging and obtain the resolution limit given by the effective de Broglie wavelength λ/N where N is the number of entangled phonons ...

Quantum positron acoustic waves
Physics of Plasmas, 2014Nonlinear quantum positron-acoustic (QPA) waves are investigated for the first time, within the theoretical framework of the quantum hydrodynamic model. In the small but finite amplitude limit, both deformed Korteweg-de Vries and generalized Korteweg-de Vries equations governing, respectively, the dynamics of QPA solitary waves and double-layers are ...

Physical acoustics in quantum fluids
The Journal of the Acoustical Society of America, 1975Superfluid helium is rich in the number of wave propagation modes which occur because it behaves as though it is composed of two fluids one of which is superfluid and the other a normal fluid. Four recognized modes are named first, second, third and fourth sound, of which all but the first occur only in quantum fluids.

Acoustic Analogies for Quantum Mechanics
2004In Chap. 2, we considered the analogy between the propagation of electromagnetic waves and quantum waves, based on the formal similarity between the Helmholtz and the Schrodinger equation. However, a similar analogy holds for sound waves. This is to be expected since sound waves are not so different from electromagnetic waves.

Acoustical phonon dephasing in GaAs quantum dots
Microelectronics Journal, 2005Abstract We present results on the acoustical phonon dephasing for a single GaAs quantum dot. Micro photoluminescence ( μ -PL) is used to observe the temperature dependence of the exciton line in self-assembled GaAs semiconductor single quantum dots (QDs). The observation of the PL with temperature shows that there are two different states within the

Quantum Pseudospin Acoustics in Liquids
1979The realization of Zavoiski’s ideas concerning acoustic EPR and NMR in fluids are discussed. A general relation between heat fluctuations and sound perturbations is found. Formulas for dipole-dipole and hyperfine AEPR and ANMR are derived. Experimental results for sound modulation of proton spin echoes in aqueous solutions of CuSO4·5H2O are presented.
