Key facts
- Today’s Google Doodle celebrates World Quantum Day 2026, and their team is explaining what makes quantum computing so exciting in a new video
- Unlike a classical bit, which is restricted to a binary state of 0 or 1, a qubit can exist in a combination of both
- Today’s Google Doodle marks World Quantum Day by incorporating the Bloch Sphere into their logo
- In 1981, physicist Richard Feynman famously observed that because nature is quantum, they would eventually need to build computers that operate on those same principles to truly understand it
Summary
Quantum computers can solve complex problems that normal computers can't. "Answering your trending questions on World Quantum Day" explains Google's quantum computing mission. Quantum computers use qubits, which can be 0, 1, or a combination, unlike regular bits. Google's working on systems to protect qubits from "decoherence," or losing quantum information.
