Clarifying the New Problem for Quantum Mechanics: Reply to Vaidman

Goldenberg and Vaidman Reply.

Goldenberg and Vaidman Reply: Peres [1] claims that our protocol (GV) [2] does not present any novel feature, and it is very similar to the oldest protocol of Bennett and Brassard (BB84) [3]. 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 se...

the algorithm for solving the inverse numerical range problem

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.

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 ...

Reply to No Contradictions between Bohmian and quantum mechanics

When these are substituted into his equation (17), the right hand side of his equation (18) vanishes. What Marchildon’s calculations have, in fact, established is that the assumption of translation invariance (Fraunhoffer diffraction and plane waves) imposed by me in my papers are sufficient but not necessary to obtain the basic result, namely that the trajectories are symmetrical at all times ...
