Protecting a Bosonic Qubit with Autonomous Quantum Error Correction
Jeffrey M. Gertler, Brian Baker, Juliang Li +3
To build a universal quantum computer from fragile physical qubits, effective implementation of quantum error correction (QEC) is an essential requirement and a central challenge.…
Universal gates for protected superconducting qubits using optimal control
Mohamed Abdelhafez, Brian Baker, Andras Gyenis +4
We employ quantum optimal control theory to realize quantum gates for two protected superconducting circuits: the heavy-fluxonium qubit and the 0- qubit. Utilizing automatic dif…
Observation and stabilization of photonic Fock states in a hot radio-frequency resonator
Mario F. Gely, Marios Kounalakis, Christian Dickel +5
Detecting weak radio-frequency electromagnetic fields plays a crucial role in wide range of fields, from radio astronomy to nuclear magnetic resonance imaging. In quantum mechanics…
Adaptive Rotating-Wave Approximation for Driven Open Quantum Systems
Brian Baker, Andy C. Y. Li, Nicholas Irons +2
We present a numerical method to approximate the long-time asymptotic solution to the Lindblad master equation for an open quantum system under the influence of an ex…
Realization of a system with metastable states of a capacitively-shunted fluxonium
Nathan Earnest, Srivatsan Chakram, Yao Lu +9
We realize a system in a superconducting circuit, with metastable states exhibiting lifetimes up to 8\,ms. We exponentially suppress the tunneling matrix elements involved in s…
