Alice & Bob, a quantum computing company specializing in “Cat qubits,” has published its first white paper outlining a five-year roadmap to deliver fault-tolerant quantum computing. The plan, targeting 100 high-fidelity logical qubits by 2030, […]
Can insights from topology—the study of the properties of 3D objects that persist when an object is stretched or compressed—be applied in the field of quantum information processing? Juan Lin, Shou-Bang Yang, Fan Wu, and […]
Insider Brief: Graph Transformers use global attention mechanisms to model relationships across all graph nodes, excelling in tasks like node classification, link prediction, and graph classification. Traditional Graph Transformers often overlook graph-specific patterns like topology […]
Insider Brief: The University of the Andes has announced Colombia’s first quantum computer, making an impact on education and research by enabling students and professors to explore quantum computing concepts and applications. The quantum computer, […]
Quantum 8, 1551 (2024). https://doi.org/10.22331/q-2024-12-04-1551 The exponential convergence to invariant subspaces of quantum Markov semigroups plays a crucial role in quantum information theory. One such example is in bosonic error correction schemes, where dissipation is […]

Quantum 8, 1550 (2024). https://doi.org/10.22331/q-2024-12-04-1550 Quasiprobability has become an increasingly popular notion for characterising non-classicality in quantum information, thermodynamics, and metrology. Two important distributions with non-positive quasiprobability are the Wigner function and the Glauber-Sudarshan function. […]
Quantum 8, 1549 (2024). https://doi.org/10.22331/q-2024-12-04-1549 We present a classical algorithm for simulating universal quantum circuits composed of “free” nearest-neighbour matchgates or equivalently fermionic-linear-optical (FLO) gates, and “resourceful” non-Gaussian gates. We achieve the promotion of the […]
Scientists at the University of Würzburg and the German national metrology institute (PTB) have carried out an experiment that realizes a new kind of quantum standard of resistance. It’s based on the Quantum Anomalous Hall […]
Before he became a decorated pioneer of artificial intelligence, Raj Reddy grew up far from a computer lab. As a child in the 1940s, he lived in rural Katur, Andhra Pradesh, India. His one-room schoolhouse […]
