Quantum 5, 529 (2021). https://doi.org/10.22331/q-2021-08-20-529 We initiate the study of quantum algorithms for escaping from saddle points with provable guarantee. Given a function $fcolonmathbb{R}^{n}tomathbb{R}$, our quantum algorithm outputs an $epsilon$-approximate second-order stationary point using $tilde{O}(log^{2} […]

Xanadu Quantum Technologies is a Canadian quantum computing hardware and software with US$145 million of funding. In May, 2021, they raised US$100M in Series B financing. Bessemer Venture Partners led the round with participation from […]
PRESS RELEASE — Quantum eMotion Inc. (QeM) is participating in the Hudson Institute’s Quantum Alliance Initiative (QAI), an international consortium of companies, institutions, and universities whose mission is to raise awareness and develop policies which […]
Scientists have taken the clearest picture yet of electronic particles that make up a mysterious magnetic state called quantum spin liquid (QSL). Click to rate this post! [Total: 0 Average: 0]You have already voted for […]
An exotic form of magnetism has been discovered and linked to an equally exotic type of electrons, according to scientists who analyzed a new crystal in which they appear at the National Institute of Standards […]
Quantum 5, 528 (2021). https://doi.org/10.22331/q-2021-08-19-528 It is well known that by repeatedly measuring a quantum system it is possible to completely freeze its dynamics into a well defined state, a signature of the quantum Zeno […]
Graph theory isn’t enough. The mathematical language for talking about connections, which usually depends on networks — vertices (dots) and edges (lines connecting them) — has been an invaluable way to model real-world phenomena since […]
Quantum 5, 527 (2021). https://doi.org/10.22331/q-2021-08-19-527 By taking a Poisson limit for a sequence of rare quantum objects, I derive simple formulas for the Uhlmann fidelity, the quantum Chernoff quantity, the relative entropy, and the Helstrom […]
