"twisted 45° angle cuprate van der Waals heterostructure BSCCO superconducting capacitively shunted qubit circuits with protection from noise by achieving circuit's symmetry and not of its placement, removeing need for tuning or flux... encodes in parity-preserving eigenstates, read-out superconducting resonator... orders magnitude improved relaxation time... quasi-particle induced dissipation exponentially suppressed... built-in many-body wavefunction for current-phase relation with dominant 2 Copper pair tunneling term"
