One of the most challenging problems in the computational study of localization in quantum manybody systems is to capture the effects of rare events, which requires sampling over exponentially many disorder realizations. We implement an efficient pro

Qubit-State Purity Oscillations from Anisotropic Transverse Noise

Autor: Rower, David A., Hida, Kotaro, Ateshian, Lamia, Zhang, Helin, An, Junyoung, Hays, Max, Muschinske, Sarah E., McNally, Christopher M., Alipour-Fard, Samuel C., Assouly, Réouven, Rosen, Ilan T., Niedzielski, Bethany M., Schwartz, Mollie E., Serniak, Kyle, Grover, Jeffrey A., Oliver, William D.

We explore the dynamics of qubit-state purity in the presence of transverse noise that is anisotropically distributed in the Bloch-sphere XY plane. We perform Ramsey experiments with noise injected along a fixed laboratory-frame axis and observe osci

Quantum error correction provides a path to reach practical quantum computing by combining multiple physical qubits into a logical qubit, where the logical error rate is suppressed exponentially as more qubits are added. However, this exponential sup
