Here we study thermodynamics in the opposite regime -- at both the nano scale, and when quantum effects become important. Applying results from quantum information theory we construct a theory of thermodynamics in these extreme limits. We derive a criteria for thermodynamical state transitions, and find two free energies: one which determines the amount of work which can be extracted from a small system in contact with a heat bath, and the other which quantifies the reverse process. They imply that generically, there are additional constraints which govern spontaneous thermodynamical processes. We find that there are fundamental limitations on work extraction from nonequilibrium states, due to both finite size effects which are present at the nano scale, as well as quantum coherences. This implies that thermodynamical transitions are generically irreversible at this scale, and we quantify the degree to which this is so.

Title: Running Grover's Algorithm on a 2-Qubit Quantum Processor.
Abstract:
We operate a superconducting quantum processor consisting of two tunable
transmon qubits coupled by a swapping interaction, and equipped
with non destructive single-shot readout of the two qubits [1]. With this
processor, we run the Grover search algorithm among four objects and
find that the correct answer is retrieved after a single run with a success
probability between 0.52 and 0.67, significantly larger than the 0.25
achieved with a classical algorithm. This constitutes a proof-of-concept
for the quantum speed-up of electrical quantum processors [2].

Spin current phenomena: new impetus to spintronics
Sergio Machado Rezende
Departamento de Física, Universidade Federal de Pernambuco, Recife, PE, Brazil
Former Minister of Science of Brazil
In recent years several phenomena have been discovered in magnetic nanostructures in which the transport of carriers depends on their spin. In addition to the long time known charge and heat currents, these phenomena also involve spin currents. Among them there are the spin Hall effect (SHE), the inverse spin Hall effect (ISHE) and the spin Seebeck effect (SSE). These effects make possible the conversion from one type of current to another in very efficient processes opening new possibilities for the development of spintronics. We will review recent developments in this area and present new results obtained with the spin Hall and spin Seebeck effects.
