The four pillars of quantum technology are quantum computing, quantum communication, quantum sensing (metrology), and quantum simulation. In 2016, China’s Micius satellite demonstrated satellite-based quantum key distribution by distributing entangled photons between ground stations over 1,200 km. IBM aims to build a 4,000+ qubit machine by 2025 and demonstrated a 433-qubit processor in 2022. D-Wave’s…
