NVQLink by NVIDIA

NVIDIA CEO Jensen Huang announced NVQLink, a new open system architecture designed to connect their powerful GPU supercomputers with quantum processors (QPUs). This hybrid computing approach aims to: I have used the basis of the previous map, but I have taken the opportunity to do a revision and reorganizing components. NVQLink plays the game here, … Read more

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
