Qubitchi

Qubitchi is a virtual pet that's actually alive — because it's a real qubit on an IBM quantum computer.

Most pets are made up. Qubitchi isn't. Adopt one and you're adopting a genuine quantum bit on real superconducting hardware, chilled to fifteen millikelvin — a hair above absolute zero. Its mood is its physics: when the qubit holds a clean quantum state, your pet is thriving. When noise creeps in and the qubit starts to forget — decoherence, the central problem of quantum computing — your pet grows drowsy, unwell, and eventually decoherent. Nothing is faked. Qubitchi is a window onto a real machine.

HOW IT WORKS • Every reading comes from live IBM Quantum telemetry — coherence times (T1/T2), calibration, and queue depth. • Health is judged against each qubit's own 30-day baseline, never an absolute scale. Every qubit is different, so a "good" chip at its own normal is just as healthy as a "great" one at its. • Tap your egg to hatch it, then watch your pet grow from hatchling to adult over days.

WHAT YOU CAN DO • Adopt any qubit on any available backend — each is its own pet, with its own age. • Follow a 7-day coherence chart, like a paediatric growth chart for a quantum bit. • Explore the neighbourhood — the other qubits sharing your pet's chip in IBM's heavy-hex layout. • Read the diary — a running log of how your pet's mood has shifted. • Earn badges for real milestones: holding a state past 100 microseconds, surviving full decoherence, bouncing back from a rough spell. • Climb the Quantum League — live leaderboards ranking every qubit on the fleet by coherence, health, and stability. • Browse your menagerie — every qubit you've ever adopted, in one place.

LEARN BY CARING Decoherence is the hardest idea in quantum computing to feel in your gut. Qubitchi makes it personal: you come to understand what T2 means because your pet's life depends on it. No equations required — just attention.

PRIVATE BY DESIGN Qubitchi collects nothing about you. It fetches public hardware data and keeps your adopted pets on your device. No accounts, no tracking, no ads.
