by Amara Graps The BB84 protocol In 1984, Brassard and Bennett presented their 4-page, conference paper, which described the BB84 algorithm, thus fixing in history the first quantum cryptography protocol for the Quantum Key Distribution (QKD) […]
Insider Brief: The National Quantum Initiative Advisory Committee (NQIAC) released a report emphasizing the strategic importance of quantum networking for U.S. national security and economic growth, calling for sustained investments in research, development, and workforce […]
The apparent weirdness of the quantum world is often exemplified by the paradox of Schrödinger’s imaginary cat that exists in a limbo state of being both alive and dead until looked upon by an observer. […]
Insider Brief According to a report, China leads in quantum communication and matches the U.S. in quantum sensing, but lags behind in quantum computing, particularly in hardware and practical systems. China’s approach focuses on transforming […]
The bottom of the ocean is cold, dark and under extreme pressure. It is not a place suited to the physiology of us surface dwellers: At the deepest point, the pressure of 36,200 feet of […]
Insider Brief: PsiQuantum CEO Pete Shadbolt announced a Test & Characterization Lab at Griffith University, set to open in early 2025. The lab will offer hands-on experience for engineers and physicists as well as focus […]
Quantum 8, 1466 (2024). https://doi.org/10.22331/q-2024-09-09-1466 In lumped-element electrical circuit theory, the problem of solving Maxwell’s equations in the presence of media is reduced to two sets of equations, the constitutive equations encapsulating local geometry and […]
Researchers have demonstrated a new multi-functional device that could help advance the scalability of solid-state color centers, enabling them to be used in larger and more complex quantum computers and networks. As efficient photon-spin interfaces, […]
Solving the problem of error is essential for the practical application of quantum computing technologies that surpass the performance of digital computers. Information input into a qubit, the smallest unit of quantum computation, is quickly […]
Quantum 8, 1465 (2024). https://doi.org/10.22331/q-2024-09-09-1465 We present an open-source database of superconducting quantum device designs that may be used as the starting point for customized devices. Each design can be generated programmatically using the open-source […]
