Q402 uses no quantum hardware. "Quantum-inspired" describes classical algorithms that borrow framing from quantum computing, chiefly annealing-style optimisation. This paper states plainly what that means and what it does not.

003.1

What is meant by a virtual qubit

Brand fiction

Each of the 64 nodes in the Q402 lattice is called a virtual qubit. This is branding. A node is an agent process with a state machine, a budget and a ledger. It does not hold a quantum state and is not entangled with anything. The 8×8 layout echoes the published layouts of superconducting processors because it looks good, not because it computes anything.

003.2

Annealing as a scheduling heuristic

Established technology

Simulated annealing is a classical optimisation method from 1983. It explores a cost landscape by accepting worse solutions with a probability that falls as a temperature parameter cools. Quantum annealers implement a physical analogue. Classical simulated annealing runs on ordinary hardware and works well for assignment problems such as matching jobs to agents under budget constraints.

003.3

Bids in superposition

Speculative research

A useful metaphor is to treat an agent's candidate bids as a weighted superposition that collapses to a single committed offer once a buyer responds. In practice this is ordinary probabilistic sampling over a price distribution. The framing helps when reasoning about many simultaneous offers. It provides no quantum advantage, and we do not claim one.

003.4

Quantum certainty

Brand fiction

The network status panel reports QUANTUM CERTAINTY: 0.00%. This figure is accurate.
