A quantum secret ballot
Shahar Dolev, Itamar Pitowsky, Boaz Tamir
The paper concerns the protection of the secrecy of ballots, so that the identity of the voters cannot be matched with their vote. To achieve this we use an entangled quantum state…
Grover's Quantum Search Algorithm and Diophantine Approximation
Shahar Dolev, Itamar Pitowsky, Boaz Tamir
In a fundamental paper [Phys. Rev. Lett. 78, 325 (1997)] Grover showed how a quantum computer can find a single marked object in a database of size N by using only O(N^{1/2}) queri…
Is There More to T?
Avshalom C. Elitzur, Shahar Dolev
We present some novel results indicating that time's description in present-day physics is deficient. We use Hawking's information-erasure hypothesis to counter his own claim that…
Time-Reversed EPR and the Choice of Histories in Quantum Mechanics
Avshalom C. Elitzur, Shahar Dolev, Anton Zeilinger
When a single photon is split by a beam splitter, its two `halves' can entangle two distant atoms into an EPR pair. We discuss a time-reversed analogue of this experiment where two…
Non-Sequential Behavior of the Wave Function
Shahar Dolev, Avshalom C. Elitzur
An experiment is presented in which the alleged progression of a photon's wave function is ``measured'' by a row of superposed atoms. The photon's wave function affects only one ou…
Does Indeterminism Give Rise to an Intrinsic Time Arrow?
Shahar Dolev, Avshalom C. Elitzur, Meir Hemmo
In any physical theory that admits true indeterminism, the thermodynamic arrow of time can arise regardless of the system's initial conditions. Hence on such theories time's arrow…
