Can quantum cryptography imply quantum mechanics? reply to Smolin
Clifton, Bub, and Halvorson (CBH) have argued that quantum mechanics can be derived from three cryptographic, or broadly information-theoretic, axioms. But Smolin disagrees, and he has given a toy theory that he claims is a counterexample. Here we show that Smolin’s toy theory violates an independence condition for spacelike separated systems that was assumed in the CBH argument. We then argue ...
متن کاملCan quantum cryptography imply quantum mechanics?
It has been suggested that the ability of quantum mechanics to allow secure distribution of secret key together with its inability to allow bit commitment or communicate superluminally might be sufficient to imply the rest of quantum mechanics. I argue using a toy theory as a counterexample that this is not the case. I further discuss whether an additional axiom (key storage) brings back the qu...
متن کاملReply to recent scepticism about the foundations of quantum cryptography
The purpose of this note is to refute a critique by Hirota [1] and Yuen [2–9] concerning a basic criterion for secrecy [10, 11], which is widely used in quantum cryptography and, in particular, serves as a basis for modern security proofs of Quantum Key Distribution (QKD). We first explain this criterion and then describe Hirota and Yuen’s critique as well as the error in their argument. Secrec...
متن کاملReply to Comment: Quantum Cryptography Based on Orthogonal States?
Peres [1] claims that our protocol [2] does not present any novel feature, and it is very similar to the oldest protocol of Bennett and Brassard [3] (BB84). We completely disagree with this claim and with other points raised in the Comment. The essential novelty of our protocol is that the carrier of information is in a quantum state belonging to a definite set of orthonormal states. Any other ...
متن کاملWhat can biology bestow to quantum mechanics?
The biological hierarchy and the differences between living and non-living matter are considered from the standpoint of quantum mechanics. The most important discovering in natural sciences are in some or other way connected to quantum mechanics. There is also a bias that biological phenomena will be explained by quantum theory in future, since quantum theory already contains all basic principl...
