Hosted jobs

Queue larger simulations on shared capacity.

Save circuits to the cloud and run hosted jobs when you need more room. Team reaches up to 28 qubits on classical simulation.

Build a Bell pair and run 1024 shots.

I'll build a 2-qubit Bell circuit (H → CX) and submit 1024 shots.

How it works

Build, inspect, then scale

Start in the browser. Move to hosted jobs when qubit count or shot count needs more room.

01
Build

Open the builder or try a live demo. Drop gates on wires and watch the state update.

Who it’s for

A visual seat for quantum learning

Built for classrooms, homework, and the path from sketch to scripted jobs.

Students

See entanglement and algorithms on a Bloch sphere before you drown in matrices.

Teachers

Run lab sessions with shared demos, then send students into the hosted app for homework circuits.

Builders

Sketch visually, then switch to API keys and the CLI when batch jobs take over.

Partners

White-label EntangleX on your GPUs

For data centers and facilities that want a branded circuit platform for their buyers — one-click install, your look, your commercial path.

Your brand on the stack

Set brand name, colors, logo, and custom domain in the partner console so every buyer install ships as yours.

One-click on buyer GPUs

Copy a single install command into your hosting panel. The buyer stack comes up on their GPU or VPS with builder, jobs, and Labs.

You own the commercial relationship

Buyers pay you. After you settle with EntangleX, licenses activate on Installs so their environment stays ready.

FAQ

Straight answers

What does EntangleX run?

EntangleX is classical simulation of quantum circuits — a visual builder in the browser, hosted jobs for larger runs, and Agentic Labs to draft and submit experiments.

Who is it for?

Students learning algorithms, teachers running labs, and builders who want a visual seat before scripting batch jobs against the API.

How do credits work?

Credits are the meter for hosted runs and Labs usage. Pro and Team include a monthly credit allowance. Qubit caps and queue priority are facilities on each plan.

What happens when credits run out?

Reload credits in Billing and continue. Plan credits refresh with each billing cycle.

Can I try EntangleX before Pro or Team?

Yes. Live demos run in the browser so you can explore circuits before you pick a credit plan.

What is Agentic Labs?

A chat workspace that drafts circuits, explains steps, and submits simulation jobs when you approve.

Can I run jobs without the UI?

Yes. Create workspace API keys and submit circuits with the CLI or HTTP API for batch work.

Do you offer a partner or white-label program?

Yes. Data centers and facilities can brand EntangleX, ship one-click installs on buyer GPUs or VPS, and settle licenses after commercial close. See the Partners page or email partners@entanglex.co.
