cooper pair box in a josephson junction array We present a protected superconducting qubit based on an effective circuit element that only allows pairs of Cooper pairs to tunnel. These dynamics give rise to a nearly degenerate ground. In this article, we will cover 19 different operations you can use to fabricate your metal parts. Let’s dive right in: 1. Rolling Metal. In the fabrication sector, rolling metal is among the most often used techniques. This procedure will be .
