If you think of a single atom as a grain of sand, then a wavelength of visible light—which is a thousand times larger than the atom’s width—is comparable to an ocean wave. The light wave […]
As far as particles of light are concerned, the collective is more important than the individual. When they get to decide between two states, they will favor the one that many of their fellow particles […]
Quantum theory faces ‘cultural gaps’ as computational limits reshape entanglement understanding0 (0)
Quantum researchers in the twenty-first century are part of an international network that requires a great deal of interaction and communication. Around one hundred publications on the topic are produced every day, often by authors […]
Google Quantum AI has announced a major algorithmic breakthrough, demonstrating the first-ever verifiable quantum advantage on hardware using the out-of-time-order correlator (OTOC) algorithm, which it terms Quantum Echoes. The experiment, published in Nature, ran on […]
Qilimanjaro Quantum Tech has announced the release of QiliSDK, an open-source Python framework designed to unify digital, analog, and hybrid quantum algorithm design. The modular software development kit (SDK) reinforces Qilimanjaro’s commitment to providing full-stack […]
Insider Brief Google Quantum AI’s 65-qubit processor performed a complex physics simulation 13,000 times faster than the Frontier supercomputer, marking measurable progress toward practical quantum advantage. The experiment used a new “Quantum Echoes” algorithm to […]
Imagine a town with two widget merchants. Customers prefer cheaper widgets, so the merchants must compete to set the lowest price. Unhappy with their meager profits, they meet one night in a smoke-filled tavern to […]
Insider Brief Rydberg Technologies announced the launch of Rydberg Photonics GmbH, a Berlin-based spin-off from the Ferdinand-Braun-Institut focused on delivering compact, micro-integrated photonic engines for the global quantum technology market. The new company builds on […]
Insider Brief Q-CTRL has appointed Aaron Canciani, a leading expert in magnetic anomaly navigation and former Principal Navigation Engineer at Leidos, as Principal Scientist on its quantum sensing team. Canciani’s research in GPS-denied magnetic navigation […]
Quantum 9, 1892 (2025). https://doi.org/10.22331/q-2025-10-22-1892 We consider the maximum cut and maximum independent set problems on random regular graphs in the infinite-size limit, and calculate the energy densities achieved by QAOA for high degrees up […]
