Abstract Boson sampling (BS) is viewed to be an accessible quantum computing paradigm demonstrate computational advantage compared classical computers. In this context, the evolution of permanent calculation algorithms attracts a significant attention as simulation BS experiments involves evaluation vast number permanents. For reason, we generalize Balasubramanian–Bax–Franklin–Glynn formula, aiming efficiently integrate it into strategy Clifford and (2020 Faster boson sampling). A reduction...

The authors propose a null-hypothesis test if quantum operation acts in the Hilbert space of limited dimension, requiring statistices measurements following finite sequences repeated identical operations. Applied to several IBM Quantum qubits, most them passed but significant disagreement with two-level has been observed one case.

We improve the test to show impossibility of a quantum theory based on real numbers by larger ratio complex-to-real bound Bell-type parameter. In contrast previous theoretical and experimental proposals requires three setting for parties $A$ $C$, but also six settings middle party $B$, assuming separability sources. The this symmetric configuration imposed is $14.88$ whilst complex maximum $18$. This large difference enables us demonstrate concomitant violation IBM computer via designed...

We present a precise certification test of the dimension qubit system on public IBM quantum computer, using determinant witness and with minimal number independent parameters. achieve it by mapping Bloch sphere $\pi/2$-rotation axis angle nonplanar so-called Viviani curve. During implementation rotation single gates devices, we found majority qubits passing test, although some specific failed more than ten standard deviations. The nature those deviations has no simple explanation, as is...

We construct a null test of the two-level space qubit, which is both device independent and needs minimal number different experiments. demonstrate its feasibility on IBM Quantum, with most qubits failing by more than 10 standard deviations. The robustness against common technical imperfections, like decoherence phase shifts, supposedly negligible leakage, indicates that origin deviations beyond known effects.

Abstract A null test of the two‐level space a qubit is constructed, which both device independent and needs small number different experiments. Its feasibility demonstrated on IBM Quantum, with most qubits failing by more than ten standard deviations. The robustness against common technical imperfections, like decoherence phase shifts, supposedly negligible leakage, indicates that origin deviations beyond known effects.

It also by-product assumptions Bell about quantum nonlocality. We have tested no-signaling in qubits from IBM Quantum devices extremely large statistics, resulting significant violations. Although time and space scales principle rule out subluminal communications, there no obvious physical mechanism leading to signaling. The violation at...

A successful Machine Learning (ML) model implementation requires three main components: training dataset, suitable architecture and procedure. Given dataset task, finding an appropriate might be challenging. AutoML, a branch of ML, focuses on automatic search -- meta method that aims at moving human from ML system design process. The success the development quantum computing (QC) in recent years led to birth new fascinating field called Quantum (QML) that, amongst others, incorporates...
