A team of scientists from Princeton University has measured the energies of electrons in a new class of quantum materials and has found them to follow a fractal pattern. Fractals are self-repeating patterns that occur […]

Researchers at the National Graphene Institute at the University of Manchester have achieved a significant milestone in the field of quantum electronics with their latest study on spin injection in graphene. The paper, published recently […]
Insider Brief PsiQuantum has announced Omega, a quantum photonic chipset designed for utility-scale quantum computing, featuring high-performance photonic components manufactured at GlobalFoundries. The Omega chipset integrates single-photon qubits with telecom-grade silicon photonics, overcoming key scalability […]
Quantum 9, 1651 (2025). https://doi.org/10.22331/q-2025-02-26-1651 A key conjecture about the evolution of complex quantum systems towards an ergodic steady state, known as scrambling, is that this process acquires universal features when it is most efficient. […]
Quantum 9, 1650 (2025). https://doi.org/10.22331/q-2025-02-26-1650 The fascinating concept of coherent quantum absorber – which can absorb any photon emitted by another system while maintaining entanglement with that system – has found diverse implications in open […]
Since before she could remember, Eva Llabrés was a snorkeler. Her grandfather, a fishmonger from the Spanish island of Menorca, bought Llabrés her first mask and fins; throughout childhood, she was in the Mediterranean, spotting […]
Quantum 9, 1649 (2025). https://doi.org/10.22331/q-2025-02-26-1649 The matrix rank and its positive versions are robust for small approximations, i.e. they do not decrease under small perturbations. In contrast, the multipartite tensor rank can collapse for arbitrarily […]
Quantum 9, 1648 (2025). https://doi.org/10.22331/q-2025-02-26-1648 We study Heisenberg scaling of quantum metrology in the viewpoint of population coding. Although Fisher information has been used for a figure of merit to characterize Heisenberg scaling in quantum […]
Quantum 9, 1647 (2025). https://doi.org/10.22331/q-2025-02-26-1647 In this paper we study single qutrit circuits consisting of words over the Clifford$+mathcal{D}$ cyclotomic gate set, where $mathcal{D}=text{diag}(pmxi^{a},pmxi^{b},pmxi^{c})$, $xi$ is a primitive $9$-th root of unity and $a,b,c$ are […]
