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…
Scalable Hardware-Efficient Qubit Control with Single Flux Quantum Pulse Sequences
Kangbo Li, R. McDermott, Maxim G. Vavilov
The hardware overhead associated with microwave control is a major obstacle to scale-up of superconducting quantum computing. An alternative approach involves irradiation of the qu…
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…
Microwave-to-optical frequency conversion using a cesium atom coupled to a superconducting resonator
Bryan T. Gard, Kurt Jacobs, R. McDermott +1
A candidate for converting quantum information from microwave to optical frequencies is the use of a single atom that interacts with a superconducting microwave resonator on one ha…
