Spurious Antenna Modes of the Transmon Qubit
O. Rafferty, S. Patel, C. H. Liu +4
Superconducting qubits are resonant absorbers of pair-breaking radiation. The metal pads that form the qubit capacitance support standing wave modes at frequencies of order 100~GHz…
High-Fidelity Measurement of a Superconducting Qubit using an On-Chip Microwave Photon Counter
A. Opremcak, C. H. Liu, C. Wilen +10
We describe an approach to the high-fidelity measurement of a superconducting qubit using an on-chip microwave photon counter. The protocol relies on the transient response of a di…
Anomalous Charge Noise in Superconducting Qubits
B. G. Christensen, C. D. Wilen, A. Opremcak +9
We have used Ramsey tomography to characterize charge noise in a weakly charge-sensitive superconducting qubit. We find a charge noise that scales with frequency as over 5…
Digital coherent control of a superconducting qubit
Edward Leonard, Matthew A. Beck, JJ Nelson +15
High-fidelity gate operations are essential to the realization of a fault-tolerant quantum computer. In addition, the physical resources required to implement gates must scale effi…
A tunable quantum dissipator for active resonator reset in circuit QED
Clement H. Wong, Chris Wilen, Robert McDermott +1
We propose a method for fast, deterministic resonator reset based on tunable dissipative modes. The dissipator is based on a Josephson junction with relatively low quality factor.…
Measurement of a Superconducting Qubit with a Microwave Photon Counter
A. Opremcak, I. V. Pechenezhskiy, C. Howington +12
Fast, high-fidelity measurement is a key ingredient for quantum error correction. Conventional approaches to the measurement of superconducting qubits, involving linear amplificati…
