Most PC gamers lucky enough to be upgrading at the moment have their eyes pinned on the new hot kit. They’re out there scoping for an Nvidia 4090 (opens in new tab) or AMD’s RX7900 range (opens in new tab). But maybe they’re thinking a little too simple, a bit […]
Parity computers can perform operations between two or more qubits on a single qubit. Parity quantum computers make complicated algorithms easier to implement. In a quantum computer, quantum bits (qubits) act simultaneously as a computing unit and memory. Quantum information cannot be stored in a memory as in a conventional computer […]
Scientists think it will be particularly useful for problems that involve many variables, such as analyzing financial risk, encrypting data, and studying the properties of materials. Researchers doubt that individuals will own personal quantum computers in near future. Instead, they’ll be housed at academic institutions and private companies where they […]
Recent headlines about physicists having created a wormhole using Google’s quantum computer are misleading. Not only did they not create a wormhole in spacetime, the kind that Einstein’s equations suggest is possible, they didn’t even create a hologram of a wormhole, as the original Nature article claimed. Martin Bauer explains […]
An artistic representation of the quantum-teleportation experiment. Physicists have used a quantum computer to perform a new kind of quantum teleportation, the ability of quantum states to be transported between distant places, as though information could travel instantly. Although teleportation is an established technique in quantum technology, the purpose of […]
A part of the quantum processor. Credit: Sergey Gnuskov/NUST MISIS Russian scientists from University of Science and Technology MISIS and Bauman Moscow State Technical University were one of the first in the world to implement a two-qubit operation using superconducting fluxonium qubits. Fluxoniums have a longer life cycle and a […]
International Business Machines Corp on Wednesday said it launched its most powerful quantum computer to date called the Osprey, a 433-qubit machine that has three times the number of qubits than its Eagle machine announced last year. The number of qubits, or quantum bits, are an indication of the power […]
Machine learning can get a boost from quantum physics. On certain types of machine learning tasks, quantum computers have an exponential advantage over standard computation, scientists report in the June 10 Science. The researchers proved that, according to quantum math, the advantage applies when using machine learning to understand quantum […]
“The Chicago quantum network presents researchers with unprecedented opportunities to transmit quantum information in a real-world environment and push the boundaries of what is currently possible with quantum security protocols,” said David Awschalom, the Liew Family Professor in Molecular Engineering and Physics at the University of Chicago, director of the […]
