Rescaling interactions for quantum control
Gaurav Bhole, Takahiro Tsunoda, Peter J. Leek +1
A powerful control method in experimental quantum computing is the use of spin echoes, employed to select a desired term in the system's internal Hamiltonian, while refocusing othe…
Cost function embedding and dataset encoding for machine learning with parameterized quantum circuits
Shuxiang Cao, Leonard Wossnig, Brian Vlastakis +2
Machine learning is seen as a promising application of quantum computation. For near-term noisy intermediate-scale quantum (NISQ) devices, parametrized quantum circuits (PQCs) have…
Modelling Enclosures for Large-Scale Superconducting Quantum Circuits
P. A. Spring, T. Tsunoda, B. Vlastakis +1
Superconducting quantum circuits are typically housed in conducting enclosures in order to control their electromagnetic environment. As devices grow in physical size, the electrom…
Critical slowing down in the bistable regime of circuit quantum electrodynamics
P. Brookes, G. Tancredi, A. D. Patterson +5
We investigate the dynamics of the bistable regime of the generalized Jaynes-Cummings Hamiltonian (GJC), realised by a circuit quantum electrodynamics (cQED) system consisting of a…
Calibration of the cross-resonance two-qubit gate between directly-coupled transmons
A. D. Patterson, J. Rahamim, T. Tsunoda +8
Quantum computation requires the precise control of the evolution of a quantum system, typically through application of discrete quantum logic gates on a set of qubits. Here, we us…
Realization of a Carbon-Nanotube-Based Superconducting Qubit
Matthias Mergenthaler, Ani Nersisyan, Andrew Patterson +6
Hybrid circuit quantum electrodynamics (QED) involves the study of coherent quantum physics in solid state systems via their interactions with superconducting microwave circuits. H…
