A Josephson junction doesn't even trap any single actual physical particle. It's just a standing wave of electrical current trapped in a bounded array of geometrically crafted slabs of superconductors and insulators. It's a phenomenon that arises from the construction of the device.
Unlike fundamental particles such as photons and electrons, there is nothing substantial about the state represented by the standing wave qubit trapped in a circuit operated by a Josephson junction device. Destroy the device (or nevermind that, just never place it in a dewar flask chilled to 4 degrees kelvin, to activate it) and the phenomenon doesn't even exist. So much for whether or not matter or energy can never be created nor destroyed.
To sit there and state that, on paper, this is the same thing as an individual electron emitted as beta decay is, well... fundamentally flawed.
