Development and Demonstration of an Efficient Readout Error Mitigation Technique for use in NISQ Algorithms
Andrew Arrasmith, Andrew Patterson, Alice Boughton +1
The approximate state estimation and the closely related classical shadows methods allow for the estimation of complicated observables with relatively few shots. As these methods m…
Quantum State Discrimination Using Noisy Quantum Neural Networks
Andrew Patterson, Hongxiang Chen, Leonard Wossnig +3
Near-term quantum computers are noisy, and therefore must run algorithms with a low circuit depth and qubit count. Here we investigate how noise affects a quantum neural network (Q…
Dynamical mean field theory algorithm and experiment on quantum computers
I. Rungger, N. Fitzpatrick, H. Chen +12
The developments of quantum computing algorithms and experiments for atomic scale simulations have largely focused on quantum chemistry for molecules, while their application in co…
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…
Circuit quantum acoustodynamics with surface acoustic waves
R. Manenti, A. F. Kockum, A. Patterson +5
The experimental investigation of quantum devices incorporating mechanical resonators has opened up new frontiers in the study of quantum mechanics at a macroscopic level.…
Double-sided coaxial circuit QED with out-of-plane wiring
J. Rahamim, T. Behrle, M. J. Peterer +6
Superconducting circuits are well established as a strong candidate platform for the development of quantum computing. In order to advance to a practically useful level, architectu…
Simultaneous bistability of qubit and resonator in circuit quantum electrodynamics
Th. K. Mavrogordatos, G. Tancredi, M. Elliott +6
We explore the joint activated dynamics exhibited by two quantum degrees of freedom: a cavity mode oscillator which is strongly coupled to a superconducting qubit in the strongly c…
Surface acoustic wave resonators in the quantum regime
R. Manenti, M. J. Peterer, A. Nersisyan +3
We present systematic measurements of the quality factors of surface acoustic wave (SAW) resonators on ST-X quartz in the gigahertz range at a temperature of . W…
Excitation and detection of propagating spin waves at the single magnon level
Alexy D. Karenowska, Andrew D. Patterson, Michael J. Peterer +2
Ferro- and ferrimagnets play host to small-signal, microwave-frequency magnetic excitations called spin waves, the quanta of which are known as magnons. Over the last decade, the f…
