The core insight

Every quantum simulator stores 2n amplitudes. MDB-OS stores only the states that actually exist.

01
Sparse Register
A HashMap<u64, Complex> that stores only populated basis states. The register doesn't care how wide it is — only how many states are occupied. 64 positions with 2 populated states = 168 bytes. Not 295 exabytes.
02
peek() · fork() · replay()
Three operations that quantum hardware provably cannot have. Non-destructive state inspection. Lossless state cloning. Deterministic re-execution. These aren't debug features — they're designed capabilities.
03
Dimensional Cascade
Every binary pattern gets a geometric identity via Fibonacci-scaled coordinates converging to φ. The SuperBit B = (σ, Ψ, W, A, G) is embedded in ℝ∞, turning search into geometry instead of enumeration.

⚡
Sparse Quantum Register
HashMap<u64, Complex> with full gate set — H, X, Y, Z, S, T, CNOT, CZ, SWAP, Toffoli, Fredkin, QFT. Auto-pruning keeps memory tight. No position limit.
🔬
Algorithms
Grover's search, Deutsch-Jozsa, Bernstein-Vazirani, quantum phase estimation, variational optimization. All running on the sparse register.
🌀
SuperBit Geometry
B = (σ, Ψ, W, A, G) — the multidimensional binary primitive. Dimensional cascade coordinates via Fibonacci scaling. Geometric search instead of blind enumeration.
