Quantum computers use quantum mechanical phenomena known as superposition to manipulate and store information. To do this, they rely on quantum bits, or qubits. To maintain the qubits in a stable state the quantum computer must be kept as cold as possible. A cryostat is used to keep the quantum chip in temperatures near absolute zero. Coaxial lines are used to communicate with the quantum chip inside of the cryostat. The coaxials are currently cut and bent manually, which create a bottleneck in production.

In this study a fully automated device was designed for bending and cutting the coaxial wires used in quantum computing cryostats. It is based on Arduino MEGA microcontroller and NEMA 23 size stepper motors. The device is capable of feeding, bending and cutting the coaxial wire automatically according to desired geometry. It is being assumed that the device can meet the demands of cryostat industry that the quantum future needs.
