All-microwave leakage reduction units for quantum error correction with superconducting transmon qubits
J. F. Marques, H. Ali, B. M. Varbanov +9
Minimizing leakage from computational states is a challenge when using many-level systems like superconducting quantum circuits as qubits. We realize and extend the quantum-hardwar…
Post-fabrication frequency trimming of coplanar-waveguide resonators in circuit QED quantum processors
S. Vallés-Sanclemente, S. L. M. van der Meer, M. Finkel +9
We present the use of grounding airbridge arrays to trim the frequency of microwave coplanar-waveguide (CPW) resonators post fabrication. This method is compatible with the fabrica…
Realization of a quantum neural network using repeat-until-success circuits in a superconducting quantum processor
M. S. Moreira, G. G. Guerreschi, W. Vlothuizen +14
Artificial neural networks are becoming an integral part of digital solutions to complex problems. However, employing neural networks on quantum processors faces challenges related…
High-fidelity controlled-Z gate with maximal intermediate leakage operating at the speed limit in a superconducting quantum processor
V. Negîrneac, H. Ali, N. Muthusubramanian +9
We introduce the sudden variant (SNZ) of the Net Zero scheme realizing controlled- (CZ) gates by baseband flux control of transmon frequency. SNZ CZ gates operate at the speed l…
5-qubit quantum error correction in a charge qubit quantum computer
Dave Touchette, Haleemur Ali, Michael Hilke
We implement the DiVincenzo-Shor 5 qubit quantum error correcting code into a solid-state quantum register. The quantum register is a multi charge-qubit system in a semiconductor e…
