Among the many discoveries on matter at high pressure that garnered him the Nobel Prize in 1946, scientist Percy Bridgman discovered five different crystalline forms of water ice, ushering in more than 100 years of research into how ice...
A fundamental barrier to scaling quantum computing machines is "qubit interference." In new research published in Science Advances magazine, engineers and physicists from Rigetti Computing describe a breakthrough that can expand the size of practical quantum processors by reducing interference.

For the first time, researchers have fabricated sensing elements known as fiber Bragg gratings inside optical fibers designed to dissolve completely inside the body. The bioresorbable fiber Bragg gratings could be used for in-body monitoring of bone fracture healing...
The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers. But finding or designing materials that can host such quantum interactions is a difficult task.
"Harmonizing multiple quantum...
One of the ways that computers 'think' is by analysing relationships within large sets of data. An international team has shown that quantum computers can do one such analysis faster than classical computers, for a wider array of data...
A research team from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has found the first evidence that a shaking motion in the structure of an atomically thin (2-D) material possesses a naturally occurring circular rotation.
This rotation...
The end of the silicon age has begun. As computer chips approach the physical limits of miniaturization and power-hungry processors drive up energy costs, scientists are looking to a new crop of exotic materials that could foster a new...
Physicists at the University of Sydney have found a 'quantum hack' that should allow for enormous efficiency gains in quantum computing technologies.
As scientists at IBM, Google, Microsoft and universities across the world seek to scale-up quantum technology to make...
In a 17-mile circular tunnel underneath the border between France and Switzerland, an international collaboration of scientists runs experiments using the world's most advanced scientific instrument, the Large Hadron Collider (LHC). By smashing together protons that travel close to...
In quantum cryptography, the laws of quantum mechanics are exploited to send messages with higher security than is possible in conventional cryptographic schemes based on classical physical phenomena. In principle, quantum communication enables absolute security -- that is, no...
Current computer systems represent bits of information, the 1's and 0's of binary code, with electricity. Circuit elements, such as transistors, operate on these electric signals, producing outputs that are dependent on their inputs.
As fast and powerful as computers...
