Researchers investigate imaginary part in quantum resource theoryFurthermore, in the framework of quantum resource theory, they studied the measurement method of this resource and the transformation problem under various free operations. They successfully observed the increase of the success probability when using the complex measurement basis, which verified the important…

Greek Astronomer Confirms Einstein with his Black Hole StudyThe first image of a black hole, captured in 2019 by the team of Greek astronomer Dimitrios Psaltis, has revealed more support for Albert Einstein’s theory of general relativity. “We expect a complete theory of gravity to be different from general relativity,…
Can god be disproved using the laws of physics? An expert explains how it depends on perspectiveIf you do not believe in god, then the question is equally nonsensical, because there is not a god and nothing can travel faster than light. But when the light “set off”, the galaxy…
Can the laws of Physics help settle the debate over the existence of God?If you don’t believe in God, then the question is equally nonsensical, because there isn’t a God and nothing can travel faster than light. But when the light “set off”, the galaxy was only about 3 billion…
A quantum computer just solved a decades-old problem three million times faster than a classical computer“This work is the clearest evidence yet that quantum effects provide a computational advantage in D-Wave processors,” said Andrew King, director of performance research at D-Wave. The researchers also programmed a standard classical algorithm for…
Can the laws of physics disprove God?The Conversation’s new series, co-published with BBC Future, seeks to answer our readers’ nagging questions about life, love, death and the universe. If you don’t believe in God, then the question is equally nonsensical, because there isn’t a God and nothing can travel faster…
In a first, RRI transfers quantum encryption key safely between buildingsThis thus revolutionises security as we know it, providing a paradigm change to the existing architectures,” RRI said. led by Prof Urbasi Sinha, is India’s first project on satellite-based long distance quantum communications. The breakthrough assumes importance because quantum technologies…
Physicists Need to Be More Careful with How They Name ThingsTamer alternatives such as “quantum advantage,” “quantum computational supremacy” and even “quantum ascendancy” have been proposed, but none have managed to supplant Preskill’s original term. But the context of “quantum supremacy,” which Pinker neglects, is that of a historically white,…
IBM’s Quantum computer links two quantum revolutionsToday, just like wave-particle duality, entanglement sparked next-generation technological applications, especially parallel manipulation of quantum objects, which is central for quantum computing. “Using the IBM Q quantum computer, we have experimentally verified for the first time the relationship that tightly binds quantum entanglement and…
D-Wave demonstrates performance advantage in quantum simulation of exotic magnetism“Successfully demonstrating such complex phenomena is, on its own, further proof of the programmability and flexibility of D-Wave’s quantum computer,” said D-Wave CEO Alan Baratz. ” This work is the clearest evidence yet that quantum effects provide a computational advantage in…
