The world will not throw away three billion phones and laptops to use quantum computers. Quantpul is building the protocol layer that lets them talk — securely, on demand, without replacement.
By 2030, fault-tolerant quantum machines will be commercially accessible — through a handful of providers, by API, by the second. Most enterprises will need that capacity occasionally: for materials simulation, optimization, post-quantum cryptography, signal analysis.
No-one will replace their laptop or phone to access it. The cost is wrong. The form factor is wrong. The data is on the existing device. The right answer is a protocol — a thin, audited layer that delegates quantum workloads from the device you already own to the machine you're renting by the second.
That layer needs three things to be trustworthy: identity that survives a quantum break, accounting that's verifiable, and fallback to classical compute when the qubit budget runs out. We're building all three.
Every active phone, tablet, and laptop assumes classical-only crypto. Quantum access requires a new identity model that doesn't break web2.
A signed delegation envelope. The classical device authorizes a workload; a quantum operator runs it; a verifier confirms the result. All keys, all data, all receipts on chain.
The protocol is public and open. The reference SDKs, the developer cloud, and the hardware partnership network are not. Same playbook as TCP/IP → Cloudflare.
The Quantpul Bridge sits between a classical client and a quantum operator. A workload travels as a signed envelope, authorized by a post-quantum key on the client. The operator runs the workload, returns a result with its own signature, and the verifier checks both before the envelope is closed.
Crucially, the client never holds the quantum hardware itself — and never has to upgrade past a software patch. The hardware partner pays compute by the qubit-second; the user pays in credits via the Quantpul SDK.

Independent forecasts converge on a quantum services market crossing $6B by 2030 and $25B+ by 2035, with cloud-delivered access making up the majority. Quantpul monetizes the access layer, not the hardware.
Our base case targets a 4% take rate on bridged compute, expanding to identity and developer tooling. A 1.5% share of cloud quantum spend in 2030 yields a $90M run-rate.
The core of the Quantum Bridge relies on heavily peer-reviewed, open-source post-quantum cryptographic standards. We publish our intermediate findings, protocol specifications, and security proofs as they mature.
