Universal Hamiltonian control in a planar trimon circuit
Vivek Maurya, Daria Kowsari, Kumar Saurav +4
Multimode circuits provide an avenue for flexible control of single and multi-qubit gates. In this work we implement a multimode circuit known as a trimon integrated in a planar ge…
Tutorial: Understanding quantum Zeno and anti-Zeno regimes
Sacha Greenfield, Archana Kamal, Justin Dressel +1
The quantum Zeno effect is a striking feature of quantum mechanics with foundational implications and practical applications in quantum control, error suppression, and error correc…
Stabilizing two-qubit entanglement with dynamically decoupled active feedback
Sacha Greenfield, Leigh Martin, Felix Motzoi +3
We propose and analyze a protocol for stabilizing a maximally entangled state of two noninteracting qubits using active state-dependent feedback from a continuous two-qubit half-pa…
Modeling low- and high-frequency noise in transmon qubits with resource-efficient measurement
Vinay Tripathi, Huo Chen, Eli Levenson-Falk +1
Transmon qubits experience open system effects that manifest as noise at a broad range of frequencies. We present a model of these effects using the Redfield master equation with a…
Electron-phonon interactions in the Andreev Bound States of aluminum nanobridge Josephson junctions
James T. Farmer, Azarin Zarassi, Sadman Shanto +2
We report continuous measurements of quasiparticles trapping and clearing from Andreev Bound States in aluminum nanobridge Josephson junctions integrated into a superconducting-qub…
Master Equation Emulation and Coherence Preservation with Classical Control of a Superconducting Qubit
Evangelos Vlachos, Haimeng Zhang, Vivek Maurya +3
Open quantum systems are a topic of intense theoretical research. The use of master equations to model a system's evolution subject to an interaction with an external environment i…
Predicting non-Markovian superconducting qubit dynamics from tomographic reconstruction
Haimeng Zhang, Bibek Pokharel, E. M. Levenson-Falk +1
Non-Markovian noise presents a particularly relevant challenge in understanding and combating decoherence in quantum computers, yet is challenging to capture in terms of simple mod…
Suppression of crosstalk in superconducting qubits using dynamical decoupling
Vinay Tripathi, Huo Chen, Mostafa Khezri +3
Currently available superconducting quantum processors with interconnected transmon qubits are noisy and prone to various errors. The errors can be attributed to sources such as op…
High-efficiency measurement of an artificial atom embedded in a parametric amplifier
A. Eddins, J. M. Kreikebaum, D. M. Toyli +7
A crucial limit to measurement efficiencies of superconducting circuits comes from losses involved when coupling to an external quantum amplifier. Here, we realize a device circumv…
