Quantum 5, 423 (2021). https://doi.org/10.22331/q-2021-03-29-423 Giving a convincing experimental evidence of the quantum supremacy over classical simulations is a challenging goal. Noise is considered to be the main problem in such a demonstration, hence it […]
Quantum 5, 422 (2021). https://doi.org/10.22331/q-2021-03-29-422 Parametric quantum circuits play a crucial role in the performance of many variational quantum algorithms. To successfully implement such algorithms, one must design efficient quantum circuits that sufficiently approximate the […]
At the heart of almost every large galaxy lies an object of immense proportions — a supermassive black hole. Up to billions of times more massive than our sun, these titans drive the evolution of […]
The race for the quantum computer will most likely be decided at the quantum bit (qubit) – the smallest information unit of the quantum computer. The coupling of several qubits into a computing system is […]
Over the past few decades, astrophysicists and cosmologists have gathered various observations hinting at the existence of dark matter (DM), a type of matter that does not absorb, reflect or emit light, and thus cannot […]
Bridging the gap between the cryogenically-cooled inner workings of quantum computers and the conventional electronics that control them is an outstanding challenge. Current approaches look unlikely to scale, but new research suggests optical fiber could […]
More and more, artificial intelligence is becoming part of our modern life by enabling machines to learn useful processes such as speech recognition and digital personal assistants. But, developers are still looking for ways to […]
Stars, galaxies, and everything in the universe, including our own bodies, are comprised of so-called regular matter. Regular matter includes atoms and molecules, which are made up of tiny particles, such as electrons, protons, and […]
A paper by the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) Director Ooguri Hirosi and Project Researcher Matthew Dodelson on the string theoretical effects outside the black hole photon sphere […]
Except for Value at Risk and option pricing, quantum algorithm are not often used to solve problems in finance. Indeed, such analysis are computationally too expensive to perform on classical computers. In this study, authors […]
