23 unmissable sporting matches to see live in 2026 – and how to get tickets now

Everyone enjoys watching sports sometimes, whether it’s cheering for a favorite local team or following Team GB during major events. We all look forward to seeing athletes compete on the field, pitch, or court.
![This device fabricates a two-qubit superconducting circuit from graphene, integrating it with a three-dimensional copper cavity to enable quantum interactions-specifically, a SQUID-based qubit and a single-Josephson junction qubit are capacitively coupled to a microwave resonator via [latex]C_{g1}[/latex], [latex]C_{g2}[/latex], and [latex]C_{g12}[/latex], demonstrating a pathway toward scalable quantum computation leveraging the unique properties of this two-dimensional material.](https://arxiv.org/html/2512.21213v1/Fig1.jpg)


![The architecture leverages a lattice of interconnected pentapods-distinguished by left (0) and right (1) configurations and coupled via hopping terms [latex]J_{x_L}[/latex] and [latex]J_{x_R}[/latex]-to encode quantum states [latex]|b(s_1, s_2, p)\rangle[/latex] with control qubits [latex]s_1, s_2 = \pm[/latex] and a target qubit [latex]p = 0, 1[/latex], achieving eight zero-energy degenerate eigenstates at initial parameters [latex]J_{\ell p} = 0[/latex] and demonstrating the successful implementation of both Toffoli and OR quantum gates through state tomography and precise modulation of the driving cycle.](https://arxiv.org/html/2512.21101v1/x4.png)
