What atoms are they using to entangle to create a qubit? How exactly are they entangling these qubits, and re-entangling them post-measurement? I can't find specifics on the quantum CPU architecture in terms of the actual atoms used for entanglement, and how any of the supposed qubits are re-entangled between measurements.

"The quantum computers you interact with in IBM Quantum use a physical type of qubit called a superconducting transmon qubit, which is made from superconducting materials such as niobium and aluminum, patterned on a silicon substrate. Such systems are not natural qubits, but are instead formed by isolating two energy levels out of many to form our approximate qubit."

I think IBM is superconducting
