Quantum teleportation is a fascinating process that involves transferring a particle’s quantum state to another distant location, without moving or detecting the particle itself. This process could be central to the realization of a so-called […]
There are precision measurements, and then there’s the Laser Interferometer Gravitational-Wave Observatory. In each of LIGO’s twin gravitational wave detectors (one in Hanford, Washington, and the other in Livingston, Louisiana), laser beams bounce back and […]
Alchemist Accelerator and the University of Chicago’s Polsky Center for Entrepreneurship and Innovation have partnered to launch Alchemist Chicago, a new deep tech accelerator. This initiative is designed to facilitate the transition of scientific breakthroughs […]
Quantum 9, 1801 (2025). https://doi.org/10.22331/q-2025-07-21-1801 Nonstabilizerness or `magic’ is a key resource for quantum computing and a necessary condition for quantum advantage. Non-Clifford operations turn stabilizer states into resourceful states, where the amount of nonstabilizerness […]
Quantum 9, 1800 (2025). https://doi.org/10.22331/q-2025-07-21-1800 Fault-tolerant quantum computation (FTQC) is essential to implement quantum algorithms in a noise-resilient way, and thus to enjoy advantages of quantum computers even with presence of noise. In FTQC, a […]
