Prepare-and-Measure Certified Deletion
This example protocol implements the functionality of Quantum Encryption with Certified Deletion using single-qubit state preparation and measurement.
Assumptions
Outline
The scheme consists of 5 circuits-
- Key: This circuit generates the key used in later stages
- Enc: This circuit encrypts the message using the key
- Dec: This circuit decrypts the ciphertext using the key and generates an error flag bit
- Del: This circuit deletes the ciphertext state and generates a deletion certificate
- Ver: This circuit verifies the validity of the deletion certificate using the key
