- Abstract: We propose to use a buckled plate as a qubit, where a double-well potential
is mechanically produced by pushing the plate from both the sides. The right
and left positions of the plate are assigned to be quantum states $|0\rangle $
and $|1\rangle $. Quantum effects emerge when the displacement is of the order
of picometers, although the size of a buckled plate is of the order of $1\mu
m$. The NOT gate is executed by changing the buckling force acting on the
plate, while the Pauli-Z gate and the phase-shift gate are executed by applying
electric field. A two-qubit phase shift gate is materialized with the use of an
electrostatic potential. They constitute a set of universal quantum gates. An
examination of material parameters leads to a feasibility of a
NEMS(Nano-Electro-Mechanical System)-based quantum computer.

We propose an alternative paradigm for the symmetry-informed construction of variational quantum circuits.
We achieve this by introducing horizontal quantum gates, which only transform the state with respect to the directions to those of the symmetry.
For a particular subclass of horizontal gates based on symmetric spaces, we can obtain efficient circuit decompositions for our gates through the KAK theorem.
