Quantum 9, 1720 (2025). https://doi.org/10.22331/q-2025-04-24-1720 This paper introduces the foliage partition, an easy-to-compute LC-invariant for graph states, of computational complexity $mathcal{O}(n^3)$ in the number of qubits. Inspired by the foliage of a graph, our invariant […]
Quantum 9, 1719 (2025). https://doi.org/10.22331/q-2025-04-24-1719 While in relativity theory space evolves over time into a single entity known as spacetime, quantum theory lacks a standard notion of how to encapsulate the dynamical evolution of a […]
Researchers have long recognized that quantum communication systems would transmit quantum information more faithfully and be impervious to certain forms of error if nonlinear optical processes were used. However, past efforts at incorporating such processes […]
Last week I visited Harvard and MIT, and as advertised in my last post, gave the Yip Lecture at Harvard on the subject “How Much Math Is Knowable?” The visit was hosted by Harvard’s wonderful […]
Insider Brief Researchers demonstrated secure quantum communication over 254 kilometers of existing telecom fiber using a coherence-based protocol, marking a milestone for practical quantum networks. The system maintained optical phase coherence without cryogenic cooling, using […]
Insider Brief IQM Quantum Computers will deliver Poland’s first superconducting quantum computer to Wrocław University of Science and Technology, with operations set to begin in the second quarter of this year. The 5-qubit IQM Spark […]
Insider Brief D-Wave and Davidson Technologies have completed the physical assembly of an Advantage2 annealing quantum computer in Huntsville, Alabama, marking the state’s first on-premises quantum system. The installation supports U.S. national defense objectives by […]
Insider Brief Researchers at Pacific Northwest National Laboratory have developed a new algorithm, Picasso, that reduces quantum data preparation time by 85%, addressing a key bottleneck in hybrid quantum-classical computing. The algorithm uses advanced graph […]
Insider Brief Diraq researchers have demonstrated a violation of Bell’s inequality using gate-defined quantum dots, validating a key benchmark for scalable silicon spin qubit quantum computing. The experiment achieved a Bell signal of S=2.731 and […]
