Quantum reading of quantum information
Journal 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
npj 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

Continuous entanglement distribution over a transnational 248 km fiber link
Nature Communications, 2022 Fibre-based entanglement distribution represents a key primitive for quantum applications such as QKD. Here, the authors demonstrate it across 248 km of deployed fiber, observing stable detected pair rates of 9 Hz for 110 h.

Experimental demonstration of adversarial examples in learning topological phases
Nature 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 ...

Quantum information effects [PDF]
Proceedings of the ACM on Programming Languages, 2022 We study the two dual quantum information effects to manipulate the amount of information in quantum computation: hiding and allocation. The resulting type-and-effect system is fully expressive for irreversible quantum computing, including measurement.
