Nonunitary Gates Using Measurements Only.

Phys Rev Lett

December 2024

Tel Aviv University, School of Physics and Astronomy, Tel Aviv 6997801, Israel.

Measurement-based quantum computation (MBQC) is a universal platform to realize unitary gates, only using measurements that act on a preprepared entangled resource state. By deforming the measurement bases, as well as the geometry of the resource state, we show that MBQC circuits always transmit and act on the input state but generally realize nonunitary logical gates. In contrast to the stabilizer formalism that is often used for unitary gates, we find that ZX-calculus is an ideal computation method for these nonunitary gates.

Materials that are constantly driven out of thermodynamic equilibrium, such as active and living systems, typically violate the Einstein relation. This may arise from active contributions to particle fluctuations which are unrelated to the dissipative resistance of the surrounding medium. We show that in these cases the widely used relation between informatic entropy production and heat dissipation does not hold.

Machine learning (ML) has shown great potential in the adaptive immune receptor repertoire (AIRR) field. However, there is a lack of large-scale ground-truth experimental AIRR data suitable for AIRR-ML-based disease diagnostics and therapeutics discovery. Simulated ground-truth AIRR data are required to complement the development and benchmarking of robust and interpretable AIRR-ML methods where experimental data is currently inaccessible or insufficient.

Switchable order parameters in ferroic materials are essential for functional electronic devices, yet disruptions of the ordering can take the form of planar boundaries or defects that exhibit distinct properties from the bulk, such as electrical (polar) or magnetic (spin) response. Characterizing the structure of these boundaries is challenging due to their confined size and three-dimensional (3D) nature. Here, a chemical antiphase boundary in the highly ordered double perovskite PbMgWO is investigated using multislice electron ptychography.

The moral voice in addiction and the self.

J Subst Use Addict Treat

January 2025

Department of Criminology, Bar-Ilan University, Ramat Gan, Israel.

Background: The robust literature on moral psychology research has often overlooked people struggling with addiction, partly due to social, theoretical, and methodological biases. This has created a gap in understanding the role of moral thinking and its influence on addiction and recovery. To address this, our hermeneutic phenomenological study, the first in a series, explores the moral voice of individuals contending with addiction.

Biomolecules

January 2025

Department of Chemistry and Institute of Nanotechnology and Advanced Materials, Faculty of Exact Sciences, Bar-Ilan University, Ramat-Gan 5290002, Israel.

Ctr1 is a membrane-spanning homotrimer that facilitates copper uptake in eukaryotic cells with high affinity. While structural details of the transmembrane domain of human Ctr1 have been elucidated using X-ray crystallography and cryo-EM, the transfer mechanisms of copper and the conformational changes that control the gating mechanism remain poorly understood. The role of the extracellular N-terminal domains is particularly unclear due to the absence of a high-resolution structure of the full-length hCtr1 protein and limited biochemical and biophysical characterization of the transporter in solution and in cell.

Background: Stigma is the experience of feeling different from socially accepted norms which can lead to personal devaluation or fear of disapproval from others. For men and women experiencing infertility, stigma has been associated with psychological distress, feelings of otherness in relation to people with children, and selective disclosure with others about their infertility challenges. However, there are few studies which examine how infertility stigma and being open with others are related to depressive symptoms and meaning in life for men and women diagnosed with infertility.
