1. A device for reducing the effects of mechanical vibrations on qubit fidelity, the device comprising:
a platform;
one or more folding mirrors; and
a confining device configured to hold at least one qubit in a position, the one or more folding mirrors and the confining device are rigidly attached to the platform, the one or more folding mirrors are configured to receive a first optical beam and a second optical beam parallel to each other and redirect one or both of the first optical beam and the second optical beam to the qubit, and the platform is configured to move in response to the mechanical vibrations while sources of the first optical beam and the second optical beam are mechanically decoupled from the platform.
