Probing quantum information propagation with out-of-time-ordered correlators [PDF]

open access: yesNature Physics, 2021
Interacting many-body quantum systems show a rich array of physical phenomena and dynamical properties, but are notoriously difficult to study: they are analytically challenging and exponentially hard to simulate on classical computers.

Quantum reading of quantum information

open access: yesJournal of Physics A: Mathematical and Theoretical, 2023
Abstract We extend the notion of quantum reading to the case where the information to be retrieved, which is encoded into a set of quantum channels, is of quantum nature. We use two-qubit unitaries describing the system-environment interaction, with the initial environment state determining the system’s input-output channel and hence the

Towards practical quantum computers: transmon qubit with a lifetime approaching 0.5 milliseconds

open access: yesnpj Quantum Information, 2022
Here we report a breakthrough in the fabrication of a long lifetime transmon qubit. We use tantalum films as the base superconductor. By using a dry etching process, we obtained transmon qubits with a best T 1 lifetime of 503 μs. As a comparison, we also

Experimental demonstration of adversarial examples in learning topological phases

open access: yesNature Communications, 2022
Machine learning has been applied to problems in condensed matter physics, but its performance in an experimental setting needs testing. Zhang et al. study the effects of adversarial perturbations on a neural-network-based topological phase classifier ...

Experimental unsupervised learning of non-Hermitian knotted phases with solid-state spins

open access: yesnpj Quantum Information, 2022
Non-Hermiticity has widespread applications in quantum physics. It brings about distinct topological phases without Hermitian counterparts, and gives rise to the fundamental challenge of phase classification. Here, we report an experimental demonstration
