Quantum logic gate analogies in nonlinear acoustics
Journal of the Acoustical Society of AmericaThis study introduces a framework using acoustic phase bits (phibits) as classical analogs to quantum bits for realizing quantum-like gates. These phibits are realized on a metastructure composed of aluminum rods glued with epoxy. First, we realize a single phibit gate in a general form for a Bloch sphere representation, providing a foundation for ...

ACOUSTIC POLARON IN CYLINDRICAL QUANTUM WIRES
Modern Physics Letters B, 2012The ground state energies and the derivates of the acoustic polaron in cylindrical quantum wire systems are performed by using the Huybrechts-like variational approach. The criterions for presence of the self-trapping transition of the acoustic polaron in cylindrical quantum wires are determined qualitatively.

Quantum mechanical representation of acoustic streaming and acoustic radiation pressure
Physical Review E, 2001We discuss acoustic streaming and acoustic radiation pressure from the viewpoint of energy and momentum of acoustic waves, using a quantum mechanical representation of acoustic waves. We represent the energy epsilon and momentum mu of acoustic waves as epsilon=n(p)homega and mu=n(p)hk; here n(p) is the phonon density, omega is the frequency, k is the ...

Quantum entanglement for acoustic spintronics
Physical Review A, 2004We consider the entanglement of spins for two electrons contributing to the acoustoelectric current driven by a surface acoustic wave (SAW) in two adjacent narrow channels by calculating their exchange energy $(J)$. The channels belong to an acoustic nanocircuit which comprises a network of quasi-one-dimensional pinched-off channels serving as wires ...

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.
