  This paper discusses the development of a novel setup to achieve Phonon
Antibunching at near Kelvin temperaturesusing carbon nanotubes. A previously
experimentally studied electro-mechanical single carbon nanotube setup is
pro-posed to be modified by the addition of another coupled nanotube. This
modified set-up is then described analytically,and low temperature
approximations to the mechanical energy are used to obtain the quantum
Hamiltonian. The sta-tionary Liouville-Von Neumann master equation is then used
to demonstrate antibunching at near Kelvin temperaturesusing the proposed
design. The achievement of phonon antibunching at such large temperatures
suggests a deeperstudy into the use of carbon nanostructures in this field. It
also brings the possibility of using phonon antibunching forquantum computing
and sensors a step closer to reality.
