Abstract
One or more electronic systems, electronic structures and/or methods provided herein relate to quantum state measurement while suppressing measurement-induced state transition in a superconducting qubit. An electronic system can comprise a superconducting qubit coupled to a tunable coupler qubit (TCQ), and a microwave drive port coupled to the TCQ. A resonator can be coupled between the TCQ and the microwave drive port. The resonator can be coupled to the microwave drive port by direct capacitive coupling or inductive coupling. The superconducting qubit can be coupled to the TCQ by a pair of parallelly-arranged coupling capacitors having equal capacitance to one another, or the resonator can be coupled to the TCQ by a pair of parallelly-arranged coupling capacitors having equal capacitance to one another.
