Entropy incorporates quantum fluctuation

Entropy incorporates quantum fluctuation
Classical thermodynamics was born in the first half of the nineteenth century as a response to the industrial revolution’s need for optimised machines, engines and motors. It focused on calculating such quantities as useful work, dissipated energy and efficiency. According to the second law of thermodynamics, mechanical energy can be completely converted into thermal energy but thermal energy cannot be completely converted into mechanical energy.

Single-photon emitter could change quantum info-processing

Single-photon emitter could change quantum info-processing
Los Alamos National Laboratory has produced the first known material capable of single-photon emission at room temperature and at telecommunications wavelengths. These carbon nanotube quantum light emitters may be important for optically-based quantum information processing and information security, while also being of significant interest for ultrasensitive sensing, metrology and imaging needs and as photon sources for fundamental advances in quantum optics studies.

Finally a specific application for quantum computers

Finally a specific application for quantum computers
  Science and the IT industry have high hopes for quantum computing, but descriptions of possible applications tend to be vague. Researchers at ETH Zurich have now come up with a concrete example that demonstrates what quantum computers will actually be able to achieve in the future.

Traditional mechanics controls quantum computers

Traditional mechanics controls quantum computers
An international team of researchers has now succeeded in extracting a fault tolerant manipulation of quanta from an effect of classical mechanics. The motion of a tennis racket in the air can help predict the behaviour of quanta. “Using an analogy from classical physics aids us in more efficiently designing and illustrating control elements for phenomena in the quantum world,” reports Stefan Glaser, professor in the Department of Chemistry at the Technical University of Munich (TUM).

Infineon demonstrates first post-quantum cryptography on contactless security chip

Infineon demonstrates first post-quantum cryptography on contactless security chip
Due to their computing power, quantum computers have the disruptive potential to break various currently used encryption algorithms. Infineon Technologies is ready to provide a smooth transition from today’s security protocols to next-generation post-quantum cryptography (PQC). The company has now successfully demonstrated the first PQC implementation on a commercially available contactless security chip, as used for electronic ID documents.

Physicists add amplifier to quantum communication toolbox

Quantum encryption using single photons is a promising technique for boosting the security of communication systems and data networks, but there are challenges in applying the method over large distances due to transmission losses. Using conventional optical amplification doesn't help as this disrupts the quantum link between sender and receiver, but physicists in Europe have found a solution – heralded photon amplification – and put it to the test.

Aiming at mass-producible quantum computers

Aiming at mass-producible quantum computers
Quantum computers are experimental devices that offer large speedups on some computational problems. One promising approach to building them involves harnessing nanometer-scale atomic defects in diamond materials. But practical, diamond-based quantum computing devices will require the ability to position those defects at precise locations in complex diamond structures, where the defects can function as qubits, the basic units of information in quantum computing.

Quantum effect modifies direction of light waves

Quantum effect modifies direction of light waves
A light wave sent through empty space always oscillates in the same direction. However, certain materials can be used to rotate the direction in which the light is oscillating when placed in a magnetic field. This is known as a 'magneto-optical' effect. After much speculation spanning a long period of time, one variant of this type of effect has now been demonstrated at TU Wien for the first time.

Quantum simulator characterises quantum systems

Quantum simulator characterises quantum systems
What happened right after the beginning of the universe? How can we understand the structure of quantum materials? How does the Higgs-Mechanism work? Such fundamental questions can only be answered using quantum field theories. These theories do not describe particles independently from each other; all particles are seen as a collective field, permeating the whole universe.

Quantum Communication: how to avoid detrimental noise?

Quantum Communication: how to avoid detrimental noise?
Scientists have been working intensely on developing methods for quantum information transfer. This would enable tap-proof data transfer or, one day, even the linking of quantum computers. Quantum information transfer requires reliable information transfer from one quantum system to the other, which is extremely difficult to achieve. Independently, two research teams – one at the University of Innsbruck and the other at TU Wien - have now developed a new quantum communication protocol.
