Trapped neutral atoms have become a prominent platform for quantum science, where entanglement fidelity records have been set using highly-excited Rydberg states. However, controlled two-qubit entanglement generation has so far been limited to alkali species,
In a step toward practical quantum computing, researchers from MIT, Zapata Computing and Google have designed a system that can verify when quantum chips have accurately performed complex computations that classical computers can’t. Noisy Intermediate
Scientists from the U.S. Department of Energy’s (DOE) Argonne National Laboratory and the University of Chicago launched a new testbed for quantum communication experiments. The Argonne quantum loop consists of a pair of connected 26-mile fiber-optic cables as 52 total
Transistors based on germanium can perform calculations for the future quantum computer. This discovery by the team of Menno Veldhorst may place the transistor at the basis of the quantum revolution. The researchers at QuTech,
The charge and spin of an electron are considered to be inseparably connected. But in a strictly one-dimensional quantum world, both quantum – spin and charge – properties are separable from each other. This fifty-year-old
Editor’s note: This post is not directly linked to quantum computing or technology but we do think it may interest our readers. Banco Bradesco, a prominent Brazilian financial institution, has been working with IBM Research
Physicists at ETH Zurich have observed a surprising twist in a quantum system caused by the interplay between energy dissipation and coherent quantum dynamics. To explain it, they found a concrete analogy to mechanics. The
Researchers at Leibniz University Hannover (LUH) and Physikalisch-Technische Bundesanstalt (PTB) have now developed a new method for ion-trapped qubits under vacuum by using electric fields above a chip structure. Qubit operations are implemented by sending microwave
January is a good period to sit back and check previous year with easy criticism and to predict new year facts with a fair dose of ‘realistic’ optimism. And a bit of humor (and bias?)
As the building block in symmetric cryptography, designing Boolean functions satisfying multiple properties is an important problem in sequence ciphers, block ciphers, and hash functions. However, the search of n-variable Boolean functions fulfilling global cryptographic constraints
