Beginning of next year, IBM will begin offering quantum-safe cryptography services on its public Cloud. Cryptographic algorithms are part of the Cryptographic Suite for Algebraic Lattices (CRYSTALS), based on open standards and open source technology
Researchers from the Université Paris Diderot develop the first quantum algorithm for the constrained portfolio optimization problem. The quantum algorithm can achieve a polynomial speedup over the best classical algorithms in certain conditions. Quantum techniques
The Japan government plans to accelerate its research and development of quantum cryptography technology and aims to put it into practical use starting in 2025. Japan is trying not to fall behind nations like the
Researchers from the Austrian Academy of Sciences, the University of Vienna and the University of Science and Technology of China have succeeded in teleporting complex high-dimensional quantum states what was previously only a theoretical possibility.
Quantum criticality could be a boon for qubit designers. Researchers studying the strange behavior of metal alloys called heavy fermions have made a surprising discovery that could be useful in safeguarding the information stored in
The work, reported in the August 22 issue of Nature Communications, is among the first to reveal the quantum properties of time. The flow of time doesn’t observe a straight arrow forward, but one where cause
IBM has unveiled a range of tools to help businesses be safe in the age of quantum computing, including the world’s first quantum-safe tape drive. IBM researchers, have been developing new ‘quantum-safe’ algorithms that can withstand
Finding a maximum or minimum is a fundamental building block in many mathematical models. Compared with classical algorithms, Durr, Hoyer’s quantum algorithm (DHA) achieves quadratic speed. However, its key step, the quantum exponential searching algorithm
Researchers witness quantum interference and entanglement between photons from sources 150 million km apart—the Sun and a quantum dot in their lab. The team managed to generate entangled states between photons from the two sources
Researchers from Lawrence Livermore National Laboratory (LLNL) have developed a new algorithm for solving polynomial systems of equations using a type of quantum computer called a quantum annealer. This study provides evidence that quantum annealing could
