# Supported Cloud Providers

Classiq offers integration with multiple cloud providers, to allow seamless
execution of quantum programs on multiple backends.

<Note>
  Some hardware providers may require an appropriate account.
</Note>

To estimate execution cost before running, see [Cost Estimation](/user-guide/execution/cost-estimation).

## `emulate` by provider

The SDK exposes an `emulate` flag on several backend preference types; **semantics differ by provider**:

| Provider          | Doc section                                                                                                                                                               |
