QUIC talk: Permutation-invariant quantum codes with Heisenberg ferromagnets
Abstract: A quantum code is a subspace of a Hilbert space of a physical system chosen to be correctable against a given class of errors, where information can be encoded. Ideally, the quantum code li...

Quantum Journal Club: Experimental realization of a Szilard engine with a singl
Abstract: The most succinct manifestation of the second law of thermodynamics is the limitation imposed by the Landauer principle on the amount of heat a Maxwell demon (MD) can convert into free ener...

Test of quantum commutation relations
Abstract: The uncertainty principle is at the very heart of quantum mechanics. Position, x, and momentum, p, are important physical observables to determine the mechanical properties of a system. In ...
