Is it true that quantum computers can break any cryptographic cipher?
No. While quantum computers can break traditional public-key cryptosystems like RSA and ECC using algorithms such as Shor's, they cannot break all ciphers. Numerous post-quantum cryptographic algorithms and symmetric ciphers (such as AES-256) are explicitly designed to be secure against quantum attacks.
