Enabling Technologies for Scalable Superconducting Quantum Computing
Xanthe Croot, Kasra Nowrouzi, Christopher Spitzer +21
Experiments with superconducting quantum processors have successfully demonstrated the basic functions needed for quantum computation and evidence of utility, albeit without a siza…
Protomon: A Multimode Qubit in the Fluxonium Molecule
Shashwat Kumar, Xinyuan You, Xanthe Croot +7
Qubits that are intrinsically insensitive to depolarization and dephasing errors promise to significantly reduce the overhead of fault-tolerant quantum computing. At their optimal…
Experimental verification of the treatment of time-dependent flux in circuit quantization
Jacob Bryon, D. K. Weiss, Xinyuan You +5
Recent theoretical work has highlighted that quantizing a superconducting circuit in the presence of time-dependent flux generally produces Hamiltonian terms proportional to…
Device Architecture for Coupling Spin Qubits Via an Intermediate Quantum State
X. G. Croot, S. J. Pauka, J. D. Watson +4
We demonstrate a scalable device architecture that facilitates indirect exchange between singlet-triplet spin qubits, mediated by an intermediate quantum state. The device comprise…
Gate-Sensing Charge Pockets in the Semiconductor Qubit Environment
X. G. Croot, S. J. Pauka, H. Lu +6
We report the use of dispersive gate sensing (DGS) as a means of probing the charge environment of heterostructure-based qubit devices. The DGS technique, which detects small shift…
Frequency Multiplexing for Readout of Spin Qubits
J. M. Hornibrook, J. I. Colless, A. C. Mahoney +5
We demonstrate a low loss, chip-level frequency multiplexing scheme for readout of scaled-up spin qubit devices. By integrating separate bias tees and resonator circuits on-chip fo…
Stimulated Phonon Emission in a Driven Double Quantum Dot
J. I. Colless, X. G. Croot, T. M. Stace +5
The compound semiconductor gallium arsenide (GaAs) provides an ultra-clean platform for storing and manipulating quantum information, encoded in the charge or spin states of electr…
