Dining Philosophers, Leader Election and Ring Size problems, in the quantum setting

Dorit Aharonov, Maor Ganz, Loick Magnin

We provide the first quantum (exact) protocol for the Dining Philosophers problem (DP), a central problem in distributed algorithms. It is well known that the problem cannot be sol…

A simpler proof of existence of quantum weak coin flipping with arbitrarily small bias

Dorit Aharonov, André Chailloux, Maor Ganz +2

Mochon's proof [Moc07] of existence of quantum weak coin flipping with arbitrarily small bias is a fundamental result in quantum cryptography, but at the same time one of the least…

Reference frame agreement in quantum networks

Tanvirul Islam, Loïck Magnin, Brandon Sorg +1

In order to communicate information in a quantum network effectively, all network nodes should share a common reference frame. Here, we propose to study how well m nodes in a quant…

Explicit relation between all lower bound techniques for quantum query complexity

Loïck Magnin, Jérémie Roland

The polynomial method and the adversary method are the two main techniques to prove lower bounds on quantum query complexity, and they have so far been considered as unrelated appr…

Symmetry-assisted adversaries for quantum state generation

Andris Ambainis, Loïck Magnin, Martin Roetteler +1

We introduce a new quantum adversary method to prove lower bounds on the query complexity of the quantum state generation problem. This problem encompasses both, the computation of…

Strong no-go theorem for Gaussian quantum bit commitment

Loïck Magnin, Frédéric Magniez, Anthony Leverrier +1

Unconditionally secure bit commitment is forbidden by quantum mechanics. We extend this no-go theorem to continuous-variable protocols where both players are restricted to use Gaus…
