Micius Quantum Satellite

The Micius satellite, formally known as the Quantum Experiments at Space Scale (QUESS) satellite, is the world’s first quantum communications satellite that has established a global quantum communication network. What are the core capabilities and experimental achievements of Micius? More things to be followed up.

Technical Challenges in Quantum Computing

A list of main challenges on Quantum computing for understanding better the landscape. Core Technical Challenges in Qubit Hardware Platforms Challenge Brief Description Qubit Coherence Time Quantum states lose coherence rapidly due to interactions with the environment (decoherence). Extending coherence times is critical for reliable computation. Gate Fidelity Physical quantum gates often produce errors due … Read more

Quantum Annealing

Quantum annealing is a quantum computing technique used to solve optimization problems by finding the lowest-energy state of a system. It works by encoding a problem into a mathematical energy landscape, where the best solution corresponds to the global minimum. The quantum computer then starts in a simple, easily prepared ground state and gradually evolves … Read more

Quantum computing, some basis

I’m not a quantum computing expert, I’m trying to learn how the ecosystem is organized, what problems is quantum computing trying to solve, what are the different areas… So this is the final diagram I did for myself, that will evolve, but right now it works for me. The summary of the important aspects is: … Read more
