For the most part, Bitwarden uses AES-CBC-256 for encryption, which is already quantum-resistant. Unless you store passkeys in an Org vault, you won’t have to worry about real or imagined threats from quantum computing. Please refer to the this thread and the discussions linked therein.
At the same time, TPM is not invincible either (see here and here).
Encryption of secrets is literally Bitwarden bread-and-butter and raison d’être, so there is no reason to believe that they are not already on top of the latest developments in cryptography and will make adjustments to the codebase as needed to counter any nascent threats.
