Account & Email Verification

QubitHub is open to anyone — no waitlist, no invite code. This page walks through what happens between clicking Create Account and being able to publish your first circuit.

Time to complete: ~2 minutes (including the email round-trip)

1. Register

Go to qubithub.co/register and fill in:

• Name — your display name (shown on circuits, runs, profile)
• Username — your URL handle (lowercase, alphanumeric, hyphens, ≥4 chars). This becomes qubithub.co/<username> and the namespace for all your circuits.
• Email — used for verification, account recovery, and (rarely) product updates
• Password — minimum 8 characters

You also need to agree to the Terms of Service and Privacy Policy — a checkbox at the bottom of the form. The version of each policy you agreed to is recorded with your account.

Username is permanent for now

Username changes aren’t supported yet. Pick something you’re happy seeing on your circuit URLs.

Reserved names

Some usernames are blocked — platform routes (login, dashboard, etc.), curated/QubitHub-owned names, well-known quantum framework / hardware / cloud trademarks, and platform-role addresses (admin, support, etc.). The register form tells you which tier matched and whether there’s a path to release. See Why is my chosen username or circuit name reserved? in the FAQ.

When you click Create Account, you’re logged in immediately and redirected to your dashboard — but the account is not yet verified.

2. The verification email

Within a few seconds of registering, you’ll receive an email from beta@qubithub.co with the subject “Verify your email — QubitHub”.

The email contains:

• A short message
• A Verify Email button (recommended)
• A plain-text fallback URL if the button doesn’t render

Didn’t get it?

Check your spam folder first. If it’s still missing after a minute, head to your dashboard — there’s a Verify Email banner with a Resend button (60-second cooldown between sends).

3. Click Verify Email

The link takes you to qubithub.co/verify-email?token=... and the page does the verification on load. You’ll see a brief success state and be returned to your dashboard.

Verification links expire after 24 hours. If yours expired:

1. Open your dashboard while logged in
2. Click Resend on the Verify Email banner
3. A fresh link arrives — repeat from step 3

If you click an expired link, the page tells you so — there’s no silent failure.

4. The welcome email

Right after a successful verification, a second email lands in your inbox: “Welcome to QubitHub — start building”. It includes shortcuts to:

• The curated circuit library (fork-and-run starting points)
• The CLI quickstart (pip install qubithub-sdk)
• The 60-second web tutorial

You don’t have to click anything in this email — it’s a reference for later.

5. First-run onboarding

A freshly verified dashboard is empty by design. Instead of an empty grid, you’ll see a 3-card prompt:

Card	What it does
Try a curated circuit	Jumps to a featured circuit (e.g. Bell state) you can fork and run with one click
Create your own	Goes to /circuits/new with starter templates (empty / Bell / VQE / QAOA)
60-second tutorial	A walk-through of the create-and-execute loop in the Web UI Guide

The prompt disappears once you have at least one circuit.

What partial-access looks like before verification

Some actions are gated until your email is verified:

• Creating circuits, datasets, spaces — blocked
• Forking — blocked
• Executing circuits you own — blocked

You can browse the public library and view circuits before verification — it just stops at the actions that put your name on something.

”I didn’t get the email” — troubleshooting

Symptom	Fix
Nothing in inbox after 1 min	Check spam/promotions; whitelist beta@qubithub.co
Resend button is greyed out	60-second cooldown — wait and retry
Resend fires but still nothing	Check that the email on your account is correct (typo on signup is the usual cause). Email support@qubithub.co if it persists
Link works but says “expired”	Links last 24 hours — request a fresh one from the dashboard banner
Link works but says “already used”	Verification is single-use; you’re already verified — try logging in

If you’re stuck, the Troubleshooting guide has more detail.

What QubitHub stores

When you register, QubitHub records:

• The Terms of Service version and timestamp you accepted
• The Privacy Policy version and timestamp you accepted
• Your registration analytics-consent choice (cookie banner — defaults to opt-out until you accept)
• Verification timestamp (set when you click the link)

See the Privacy Policy for the full data-flow detail.
