Abstract
Systems and techniques that facilitate hybrid readout packaging for quantum multichip bonding are provided. In various embodiments, an interposer can have a first quantum chip and a second quantum chip. In various aspects, a readout resonator (e.g., input/output port) of one or more qubits on the first quantum chip can be routed to an inner portion of the interposer. In various instances, the inner portion can be located between the first quantum chip and the second quantum chip. In various aspects, routing the readout resonator to the inner portion can reduce a number of crossings and/or intersections between input/output lines on the interposer and connection buses between qubits on the interposer.
