Modulated longitudinal gates on encoded spin-qubits via curvature couplings to a superconducting cavity Rusko Ruskov, Charles Tahan We propose entangling operations based on the energy curvature couplings of encoded spin qubits to a superconducting cavity, exploring the non-linear qubit response to a gate voltage variation. For a two-qubit (n-qubit) entangling gate we explore acquired geometric phases […]
