Interaction of paired and lined-up electrons can be manipulated in semiconductors

Posted by in categories: computing, particle physics, quantum physics

The way that electrons paired as composite particles or arranged in lines interact with each other within a semiconductor provides new design opportunities for electronics, according to recent findings in Nature Communications.

What this means for , such as those that send information throughout , is not yet clear, but hydrostatic can be used to tune the interaction so that electrons paired as composite particles switch between paired, or “superconductor-like,” and lined-up, or “nematic,” phases. Forcing these phases to interact also suggests that they can influence each other’s properties, like stability – opening up possibilities for manipulation in electronic devices and quantum computing.

“You can literally have hundreds of different phases of electrons organizing themselves in different ways in a semiconductor,” said Gábor Csáthy, Purdue professor of physics and astronomy. “We found that two in particular can actually talk to each other in the presence of hydrostatic pressure.”

To put a quantum computer on your desk, Intel has a plan unlike any other

Posted by in categories: computing, quantum physics

Quantum computers, once they become common, will complete difficult tasks thousands of times more quickly than current PCs. That could obviously threaten a classic chipmaker like Intel, but it plans to use its knowledge of silicon production to build quantum chips more quickly than its peers.

Starts Testing Smallest ‘Spin Qubit’ Chip for Quantum Computing

Posted by in categories: computing, quantum physics, space

Intel researchers are taking new steps toward quantum computers by testing a tiny new “spin qubit” chip. The new chip was created in Intel’s D1D Fab in Oregon using the same silicon manufacturing techniques that the company has perfected for creating billions of traditional computer chips. Smaller than a pencil’s eraser, it is the tiniest quantum computing chip Intel has made.

The new spin qubit chip runs at the extremely low temperatures required for quantum computing: roughly 460 degrees below zero Fahrenheit – 250 times colder than space.

The spin qubit chip does not contain transistors – the on/off switches that form the basis of today’s computing devices – but qubits (short for “quantum bits”) that can hold a single electron. The behavior of that single electron, which can be in multiple spin states simultaneously, offers vastly greater computing power than today’s transistors, and is the basis of quantum computing.

Microsoft making progress on quantum computer ‘every day’

Posted by in categories: biotech/medical, chemistry, computing, genetics, quantum physics

Microsoft is “all-in” on building a quantum computer and is making advancements “every day”, according to one of the company’s top experts on the technology.

Julie Love (above), Director of Quantum Computing, called the firm’s push to build the next generation of computer technology “one of the biggest disruptive bets we have made as a company”.

Scientists make first ‘on demand’ entanglement link

Posted by in categories: computing, internet, quantum physics

Researchers at QuTech in Delft have succeeded in generating quantum entanglement between two quantum chips faster than the entanglement is lost. Via a novel smart entanglement protocol and careful protection of the entanglement, the scientists led by Prof. Ronald Hanson are the first in the world to deliver such a quantum link on demand. This opens the door to connect multiple quantum nodes and create the very first quantum network in the world. Their results are published in Nature.

By exploiting the power of quantum entanglement, it is theoretically possible to build a invulnerable to eavesdropping. However, the realization of such a is a real challenge—it is necessary to create entanglement reliably on demand, and maintain it long enough to pass the entangled information to the next node. So far, this has been beyond the capabilities of quantum experiments.

Scientists at QuTech in Delft have are now the first to experimentally generate entanglement over a distance of two metres in a fraction of a second, on demand, and theoretically maintain this entanglement long enough to enable entanglement to a third node. “The challenge is now to be the first to create a of multiple entangled nodes—the first version of a quantum internet,” professor Hanson says.
