# Quantum Dice

> Probabilistic hardware for probabilistic algorithms.

Quantum Dice is a spin-out from the University of Oxford's Department of Physics, building the first scalable probabilistic computing platform. The company's photonics-powered hardware delivers orders-of-magnitude gains in speed and energy efficiency for NP-hard optimization problems and next-generation AI.

## Core Technologies

### ORBIT Architecture
The ORBIT Probabilistic Processing Unit (PPU) combines ultra-fast photonic p-bits with electronic control to deliver a scalable, room-temperature probabilistic computer. P-bits are probabilistic bits that fluctuate between 0 and 1 with controllable probability. By wiring many p-bits into a network and tuning their interactions, the system naturally explores and settles into low-energy configurations that correspond to high-quality solutions.

### DISC Protocol
A patented protocol that continuously monitors the quantum source of randomness to verify quality and stabilize computation. Provides precise, reproducible sampling critical for rapid convergence in probabilistic algorithms.
