In 2025, researchers unveiled the first topological quantum processor, an 8-qubit device using Majorana particles. D-Wave’s Advantage quantum annealing computer solved a complex magnetic simulation in minutes, a problem that would take classical supercomputers millions of years. In late 2024 Google debuted the 105-qubit Willow superconducting chip with unprecedented error-correction performance. IBM crossed the 1,000-qubit…

The global QKD market (including terrestrial and satellite) is projected to grow from about $0.48 billion in 2024 to $2.63 billion by 2030, a CAGR of roughly 32.6%. Space-based QKD is forecast to reach about $1.1 billion by 2030, representing roughly 40–45% of the total QKD market. China’s Micius satellite, launched in 2016, demonstrated QKD…

QUICK³ is a 3U CubeSat weighing 4 kg, led by Germany’s Technical University of Munich, and it launched on 23 June 2025 aboard SpaceX’s Transporter‑14 from Vandenberg SFB. It carries the first true single-photon source flown, a laser-pumped hexagonal boron nitride chip on a 10 × 10 × 15 cm photonic chip. True single photons…

Google Quantum AI achieved quantum supremacy in 2019 with the 54-qubit Sycamore processor performing a random circuit sampling task in 200 seconds. IBM Quantum progressed from the 127-qubit Eagle milestone in 2021 to 433-qubit Osprey in 2022, with a plan for a 1,121-qubit Condor and a long-term goal of about one million physical qubits by…

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…
