Google harnesses quantum mechanics at California lab

Google has around 20 quantum computers at its lab in Santa Barbara, where Dr Erik Lucero and his team are trying to forge the future of computing. Outside, balmy September sunshine warms an idyllic coast, as California basks in yet another perfect day. Inside, it’s minus 460 Fahrenheit (-273 Celsius) in some spots, pockets of … Read more

Full control of a six-qubit quantum processor in silicon

The six qubit quantum processor described in this article. The qubits are created by tuning the voltage on the red, blue and green wires on the chip. The structures called SD1 and SD2 are extremely sensitive electric field sensors, which can even detect the charge of a single electron. These sensors together with advanced control … Read more

Engineering robust and scalable molecular qubits

By placing molecular qubits in an asymmetric crystal array, Prof. David Awschalom and his team from him found that certain quantum states were much less sensitive to external magnetic fields. Credit: Awschalom Group, D. Laorenza/MIT The concept of “symmetry” is essential to fundamental physics: a crucial element in everything from subatomic particles to macroscopic crystals. … Read more

Chemical in cells of marine organisms enables them to survive high pressures found in deep oceans

Thjs graphic shows how the structural network of water is distorted under high pressure. Credit: University of Leeds Scientists have discovered how a chemical in the cells of marine organisms enables them to survive the high pressures found in the deep oceans. The deeper sea creatures live, the more inhospitable and extreme the environment they … Read more

Physicists find way to control detonation wave in promising new type of engine

Schematic of three-dimensional rotating detonation engine showing detonation wave. Credit: D. Schwer et. al./49th AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition Skoltech researchers have theoretically predicted synchronization—a kind of self-regulation—in detonation waves. The discovery could help tame this inherently chaotic process so as to stabilize combustion in a rotating detonation … Read more

Astronomers unveil new – and puzzling – featu

More than 15 years after the deep-space pulses of electromagnetic radio waves were first discovered, their perplexing nature … Read more

Breakthrough Prize for the Physics of Quantum Information…and of Cells

The idea of ​​using the laws of quantum mechanics for computation was proposed in 1982 by Richard Feynman. But Deutsch—who is at the University of Oxford, UK—is often credited with establishing the conceptual foundations of the discipline. Computer bits that obey quantum principles, such as superposition and entanglement, can carry out some calculations much faster … Read more

Manufacturing of quantum qubits connected with conventional computer devices

Researchers at The University of Tokyo grow a nanoscale layer of a superconducting material on top of a nitride-semiconductor substrate, which may help facilitate the integration of quantum qubits with existing microelectronics.

Superconductivity Model With 100,000 Equations Now Contains Just 4 Thanks to AI : ScienceAlert

Electrons whizzing through a grid-like lattice don’t behave at all like pretty silver spheres in a pinball machine. They blur and bend in collective dances, following whims of a wave-like reality that are hard enough to imagine, let alone compute. And yet scientists have succeeded in doing just that, capturing the motion of electrons moving … Read more
