Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits—or qubits—that are stable, meaning they are not much affected by changes in their environment. This normally needs ...

First flexible memory device using oxide ferroelectric material

For the first time, researchers have been able to deposit an ultra-thin oxide ferroelectric film onto a flexible polymer substrate. The research team used the flexible ferroelectric thin films to make non-volatile memory ...

New insight into superfluids reveals a storm at the surface

The discovery of a 'storm' layer created when superfluid helium flows across a rough surface has turned a century of understanding about one of the most important discoveries in quantum physics on its head.

Electro-optical switch transmits data at record-low temperatures

A silicon optical switch newly developed at Sandia National Laboratories is the first to transmit up to 10 gigabits per second of data at temperatures just a few degrees above absolute zero. The device could enable data transmission ...

Researchers demonstrate new type of laser

Lasers are everywhere nowadays: Doctors use them to correct eyesight, cashiers to scan your groceries, and quantum scientist to control qubits in the future quantum computer. For most applications, the current bulky, energy-inefficient ...

Cracking the mystery of perfect superconductor efficiency

In 1911, physicist Heike Kamerlingh Onnes aimed to lower mercury's temperature to as close to absolute zero as possible. He hoped to win a disagreement with Lord Kelvin, who thought metals would stop conducting electricity ...

Nucleolus forms via combination of active and passive processes

Researchers at Princeton found that the nucleolus, a cellular organelle involved in RNA synthesis, assembles in part through the passive process of phase separation – the same type of process that causes oil to separate ...

How X-rays in matter create genetoxic low-energy electrons

Researchers led by Kiyoshi Ueda of Tohoku University have investigated what x-rays in matter really do and identified a new mechanism of producing low-energy free electrons. Since the low-energy electrons cause damage to ...
